Non-irrigation and high-yielding technology [Fully enclosed hardcover planting method] Analysis ◠First of all, it introduces the source of ideas for fully enclosed hardcover planting methods; The site of the 500mm × 500mm × 50mm cement slab was used in the yard of our company. Since the ground before the pavement was not hardened, it was laid directly on the soil surface. The result was a gap between the board and the board. The grass is also not clean five or six times. After unveiling the cement board, the moisture content of the soil under the board is very high, and the grass root system is also very developed. According to this phenomenon, the trial planting was started only for drought resistance, and the output was never expected to be so high. Reinterpret four doubts; ☆ Hard plates cover the surface of the soil. The surface of the soil is completely shielded from sunlight by the hard plate. Can plants not grow? The explanation is that the roots of plants grow in dark soil without direct sunlight. Covers that do not cover hardboards are dark soil environments. The growth and development of roots in the soil requires that sunlight shines on the surface of the soil. temperature. ☆, The hard surface of the soil covering the soil is airtight, and the roots of the soil lacking oxygen cannot grow and develop. As the saying goes, a large needle-nosed hole has a large wind. The molecules of air are much smaller than those of liquid molecules. Under the effect of atmospheric pressure, the air has a very strong penetrating power. It can keep soft for a long time, so that the soft soil always maintains sufficient oxygen. After rainfall, the rainwater can also carry a large amount of dissolved oxygen and permeate into the soil along the gap between the board and the board. The air in the soil is also brewing under the regulation of temperature in the breathing. As the temperature rises during the day, the gas contained in the soil also rises, and the volume expands, resulting in a relatively high air pressure. As the soil is discharged along the gap between the plate and the plate, the temperature gradually decreases during the night. The gas temperature is also reduced, the gas volume is gradually reduced, the gas pressure is relatively reduced, under the pressure of atmospheric pressure, the fresh air is pressed into the soil, the air has a specific tendency, where the pressure is low to go there. So that the oxygen in the soil greatly exceeds the need for plant root growth. Looking at the surface of the soil by opening the hard plate, we can see that the surface of the soil has tiny unevenness. The tiny unevenness is due to the unsatisfactory flatness of the soil surface before planking and the fact that the soil has different sizes of clods and makes it hard. The contact surface between the plate and the soil surface can only reach about 60%. This poor contact surface naturally forms a lateral ventilation and water passage between the soil and the hard plate, and increases the ventilation of the soil under the hard plate. ☆, hard board covering the soil surface, because the quality of the hard plate absorbs more sunlight and more heat, the surface temperature of the hard plate is very high, when the temperature is 20 degrees, the surface temperature of the board can reach 25 degrees up and down, the temperature is 25 degrees, the board surface The temperature can reach 35 degrees. When the temperature is 30 degrees, the surface temperature can reach 50 degrees. When the temperature is 35 degrees, the surface temperature can reach 60 degrees. How does this high temperature protect the growth and development of plants? Most of the farmland sowing is in the spring. The soil temperature is about 10 degrees, the temperature is about 20 degrees, and the surface temperature is about 25 degrees, which is very conducive to the growth and development of young seedlings. In the early summer season, the temperature rises, and the surface temperature of the hard board is also When it rises, the ground part of the plant has grown taller. The lush stems and leaves, the lush stems and leaves begin to block, 70% of the sun's rays are blocked, 70% of the sun's rays cannot directly hit the surface of the hard plate, and the temperature of the hard plate surface is luxuriant. Stems and leaves are controlled within 30 degrees. When the temperature is as high as 35 degrees, the stems and leaves are more luxuriant, the sun's rays are blocked up and down by 80%, the temperature of the surface of the hard plate is also controlled within 40 degrees, and the plants themselves are temperature-controlled and self-protected. . In the fall, the leaves of plants shrink day by day, the effect of blocking the sunlight is getting smaller and smaller, the direct sunlight rate is getting larger, the surface temperature of the hard plate increases randomly, and the soil temperature also increases randomly, ensuring that the grains of autumn plants are more full . It should be noted that, in transplanting plants in spring, the roots of the seedlings must be carried by the soil, and they can survive once. The seedlings without soil should be shaded. ☆ How does the hard-covered soil maintain long-lasting porosity and permeability? The area of ​​the hard board is more than 1 square meter, which has a compressive effect on the gravity of the upper machinery and manpower, and the effect of protecting the soil from inflexion. The plant roots in the soil under the hard board are particularly developed. The root system produces a large number of capillary pores of various sizes. By the following years, these developed root systems naturally form many capillary pores, which increases the porosity and air permeability of the soil. . Because of the high moisture content of the soil below the hard board, after winter freezing, the water in the soil forms ice crystals, the volume of ice crystals expands, and the soil forms countless small spaces, increasing the looseness and permeability of the soil. 1, on the advantages of this method: ★ The traditional method of cultivation is that the ridge and ditch terraces are wavy and the ridge tables are trapezoidal. Its advantage is that the exposed area is about 1.5 times larger than the flat planting area. Its role is to expand the area of ​​sunlight that receives sunlight. It can greatly increase the temperature of the ground, which is conducive to the growth and development of the plant roots, but it has negative aspects. ☆ Artificially stipulate a certain narrow soil space for the growth and development of plant roots. ☆The root system must develop downwards for a certain distance before it begins to develop around, so that the distance and time of development along the long root system. The shape of the root growth is narrow and long in the upper part and slightly wider in the lower part, similar to the shape of a trapezoidal ridge. ☆ The soil surface area of ​​the trapezoidal ridge table is about 1.5 times larger than the surface area of ​​the soil planted by the hard board, and the evaporation of soil moisture and fertilizer is large. ☆, The soil surface of the trapezoidal ridge table has a dry soil layer of nearly 20mm thick. Although the function of the dry soil layer is the thermal insulation of the water, the effective use of trapezoidal ridged soil is more narrow, with light rain and showers, and the rainfall is 10mm. The following invalid rains cannot be fully utilized and function effectively. They evaporate in one or two days and their ability to fight drought is very weak. ☆ The bottom of the furrows compacts the soil due to the movement of the machine and the human. The roots of the plants grow to the bottom of the furrows and it is difficult to develop around them. ☆Insufficient period of plant growth, traditional planting methods have weak resistance to natural disasters, basically rely on the weather to eat, can cause low ground temperature in the early spring, soil drought, seed can not grow buds, reduce the number of days of growth, 2. The method of planting with hard board covers, the structure of the soil surface is flat, the soil under the hard board is integral, and has the following functions and characteristics under the cover of the hard board; ☆, the gap between the board and the board [the gap between the seedlings], it is to plant planting, germination, rooting, growth, leaving a place, play a role in air permeability, water seepage and plant growth and development. ☆The rigid plate can raise the maximum heat obtained by solar radiation up to 50 degrees, [this is the temperature of the early summer season], and timely conducts the temperature to the soil under the board, so that the soil temperature is higher than that of the traditional planting method. The temperature can reach up to 10 degrees, and the heat preservation effect is 2 degrees lower than the soil temperature of the traditional planting method. The high temperature of the soil increases the plant growth period. ☆ The soil space under the hard plate is more than double that of the traditional planting method. The ground temperature is high and the humidity is high. The seeds germinate and take root quickly. The root roots begin to grow less than 10 mm of the main root lateral roots, with the growth of the main lateral roots. The developmental fibrous roots also grow quickly, and most of the lateral roots and fibrous roots develop parallel to the surroundings. The overall development can be especially superior to the volume and root system of the main lateral roots of traditional planting methods. The volume of the main lateral roots is higher than traditional The planting method is 2-5 times larger, the total number of root systems is 5-10 times more, and the root system is like a cylinder as a whole. This particularly developed root system will inevitably send a large amount of soil fertilizer and moisture to the stems of the ground. Leaves and fruits. ☆The surface of the hard board is smooth, and it can concentrate the rainfall of less than 10mm rainfall and rain showers to form runoff, seep into the soil along the gap between seedlings and eyes, use the invalid rain as much as possible, and change the invalid rain. For effective rainfall, the moisture content of the soil is always kept at a high degree of moisture, and in the case of light drought, moderate drought, and severe drought, the plants are always provided with high water and fertilizer, so that the plants always maintain the momentum of rapid growth. Plant growth grabbed the time, 10 days of drought to grab 10 days of growth time, 20 days of drought to grab 20 days of growth time, increase the growth period of plants, and improve the ability of the soil to resist drought. ☆The hard plates cover the surface of the soil for many years, and all the rainfall during the non-growth season [early spring or late fall] of the plant is also incorporated into the soil under the slab to further increase the water storage capacity of the soil under the action of an impermeable hard plate. More than 90% of soil moisture cannot form water vapor, and more than 90% of fertilizers do not form biogas. They are completely stored in the liquid state and can completely control soil moisture and fertilizer evaporation by more than 90%, making the soil throughout the year. Maintain the best moist state, and maximize the use of water and nutrients for plant growth season, and further improve the drought resistance and fertility of the soil. ☆ The hard plate closely covers the surface of the soil, so that the grass seeds remaining in the soil will germinate quickly. However, under the seal of the rigid plate, it cannot grow upwards and forth, and all of them are suffocated. Only the gap between the plate and the plate is visible. With some weeds, weeds can be removed by hand. There is not much weed, and we can't use much working hours. Eggs left in the soil under the board can be converted into larvae. However, it is difficult to climb out of the ground under the pressure of the hard plate, and all of them are suffocated. . There is no weed in the field, eliminating the phenomenon of weeds competing with crops to compete for water, so that the growth of crops can be given more water and fertilizer. There are no pests in the field, which prevents the pests from causing a significant reduction in agricultural production. Without grass and pests, and without pests, the use of herbicides and pesticides in farm fields will be eliminated, and pesticide contamination from agricultural products will be controlled from the source of production. In addition, it also provides convenience for changing crops in agricultural cultivation. It can be changed every year without using herbicides. It is more convenient to change herbicides and use herbicides to cause residue of herbicides in soil. In order to change crops, at least three years after manual weeding, we can change rakes. For example, farmland with broadleaf herbicides is a kind of broad-leaved plant year after year. Coniferous plants cannot be replaced. If you change the coniferous plants, To cause a large number of production cuts, or even to result in an outbreak of production, the same plants are always planted without changing crops. Annual output does not decrease year-on-year, and the quality of agricultural products is worse than a year. Soybean quality in Heilongjiang is the problem. ☆ The surface of the soil is covered with a hard plate. The growth of some plants on the surface of the hard plate surface is; the seed is sown in the gap between the plate and the plate. Because the ground temperature is high, the seeds will germinate, take root, and sprout. The unearthed soil is very robust, with thick stems and large and thick leaves. With the gradual development of the underground root system, various nutrients and moisture are provided to the seedlings. The thick and large leaves of the seedlings are exposed to sunlight. For rapid photosynthesis and chlorophyll production, numerous micro-holes are opened during the day to inhale carbon dioxide, remove oxygen, and inhale oxygen at night to remove carbon dioxide, while also absorbing nitrogen from the air to enrich the nutrients of the plant while also excluding water from the body. With the prolongation of time, the stems of the plants grow quickly, grow taller and thicker, and the leaves are longer, longer, wider, longer and thicker. Under the effect of hard plates, the plant grows at a rate that is one-third faster than traditional planting methods. The height is three molecules higher than the traditional planting method. The blades are wide, long and thick. They are about twice as large as the traditional planting method. Because the plants grow Also the number of blades than the conventional cultivation methods, thus greatly improving the ability of plant photosynthesis, greatly increased plant uptake of nitrogen in the air. The growth of the plants, the increase of the fruits, and the fullness of the grains increased the nutrition. ☆ Water or rainwater carries fertilizers. Different terrains can easily penetrate and spread to the surrounding soil along uneven and uneven surfaces. When the temperature of sunlight reaches a certain level, the water molecules and various nutrients and trace elements move vertically upwards in the form of a liquid until they reach the surface of the soil. As the temperature continues to rise, they change from a liquid to a gaseous state and escape from the soil surface. Evaporate, go to the atmosphere, and take away a lot of heat from the soil. This is the way that our ancestors used traditional methods of cultivation for soil use. ☆ The function of fully enclosed hardcover planting technology is to control rising moisture, various microorganisms, trace elements, various nutrients and soil heat, permanently block them below the soil surface, and always exist in the form of hot, so that The soil will always maintain sufficient moisture, nutrients and temperatures. The plant is supplied with the greatest energy, so that the plant germinates, roots, grows, blooms, and results as quickly as possible. Without being affected by any natural factors, it can gradually infiltrate the extra rainwater all year round to the depths of the ground. It can also gradually make up for the over-exploitation of groundwater in previous years, raise the groundwater level, and change the groundwater level caused by over-exploitation of groundwater. The subsidence formed a funnel, which changed the unpleasant way of extracting groundwater from agricultural cultivation, especially because it could increase the temperature of the ground and increase the temperature of the moisture in the deep soil and moved upwards. During the daytime, it rose to the bottom of the board and was not gas-filled and accumulated. At night, as the temperature drops, the soil below the hard plate and the temperature of the water contained in the soil also drop at random and become heavy. Under the action of the earth's gravity, the water under the plate becomes heavier and will infiltrate the warmth of the next day. The water in the depths of the soil rises again, becomes lighter, rises, and starts again and again. Even a severely droughty soil can lift the deeper soil moisture to the surface of the soil, which is sufficient for the water content of seedlings planted in spring. ☆ Fully enclosed hard cover planting technology The vertical pressure of the hard board on the soil is 20 grams per square centimeter. The pressure on the soil is 1 square centimeter 500 grams, the soil pressure is 1 square centimeter 600 grams, and the pressure of the human through a hard plate more than 20 times the foot area to the ground is 1 square centimeter only 20 grams, almost Slightly speaking, the soil never settles and it relieves the traditional land deep-turning, deep loosening, seasonal ridging, and ploughing. The hard cover technology hard plate covers the surface of the soil forever. He can control the rain all year round in the soil, keeping the content of soil water permanently high. ☆ Hard plates cover more than 90% of the surface of the soil. They also effectively control the loss of high-quality soil on the soil surface. The rainwater does not take the topsoil. The wind does not blow the topsoil, and basically controls the land that is caused by water and soil loss. The thin phenomenon has protected the loss of soil. Desert governance, grassland degradation and desertification control, treatment of middle and low-yielding fields, treatment of saline-alkali land, and treatment of the Loess Plateau can all play their best role. This further expanded the utilization of land resources. ☆ In summary, not only has not wasted land resources, it has also more than doubled the rate of land use. It has not violated the law of biological growth, and has also increased all factors of biological growth to levels that are currently beyond the reach of agricultural methods. To ensure a substantial increase in the yield of crops, production can increase 1-2 times, the current world has no such method. ☆ Whether it is a cement board, a stone board, or a glass board, it has a certain service life. Initially, it is a small-area damage update. When a piece of damage becomes three small pieces, it cannot be used. It must be updated. At this time, the update is very easy. You can replace it with new ones, like to take the damaged ones home and praise them. After a lot of damage and updates, you can use the debris in the basic materials of the house building. Larger plates can be used as materials in the masonry walls, due to the elimination of hard plates. A large number can also be used in the construction of the basic fill of the highway, the construction of large and medium-sized reservoirs, river dams, fish ponds and other basic filler. Because the hard board is laid on the surface of the soil, the soil is always kept soft, and there is no need for site preparation during the planting process. The ground and the broken plate are large and must not be mixed with the soil. It is easy to clean up after being broken. There will be no waste of land resources. ☆ After the hardboard is covered, it will not only protect the land resources and increase the utilization of land resources, but also save the country a lot of water resources, pesticide resources, fertilizers, fertilizer resources, labor resources and fuel resources. 3, the influence of the method environment: ☆ Once this method is implemented, it will be a huge project that will have a huge impact on the environment, but it will not necessarily damage the environment. The country will guide it properly. The production of cement is a major pollution problem, but the country is forcing it. There are restrictions on the emission of dust and the emission of dust. At present, the dust and dust treatment technologies are also mature. The treatment technology will be more advanced in the future. In the future, with the economic prosperity of the growers, the country can guide the farmers toward the use of slate, the service life of the slate can reach 1,000 years, or the development of cheaper and more environmentally friendly hard board materials. ☆ Manufacture of cement hard plates requires a large amount of river sand, which will affect the river course. However, the correct and orderly guidance of the country will benefit the dredging of the river. In recent years, many rivers have dried up due to drought, and the riverbed has been exposed to wind and wind to cause sandstorms. It is a barren land, and it is also a shelved sand resource. After mining, a large sand pit can be formed for fish farming and water storage. ☆ The soil surface is closed, no insects and no grasses are used, and pesticides and herbicides are not used permanently to better protect the soil environment. More than 90% of the soil is closed, effectively controlling the evaporation of fertilizers and chemical fertilizers. Greatly reduce the emission of harmful gases to the atmosphere and protect the atmospheric pollution. After the rain, the flowing water does not carry harmful chemicals such as pesticides, chemical fertilizers, and fertilizers. It does not cause pollution of pesticides and chemical fertilizers to downstream rivers, reservoirs, and lakes, and causes downstream water bodies. Has been effectively protected, the maximum protection of the environment. 4, the practicality of the method: Practicality must focus on profitability and focus on sustainability. We must look at the present and focus on the future. ☆ With regard to the current slow development of the agricultural economy, farmers' income is also slow, and they are planted by hard board. The annual investment per mu can be reduced by more than 100 yuan, and the income can be increased by more than three times, which can greatly increase the farmers' economic income. ☆, 6mm thick corrugated tile can be used for 20 years, 1 square meter 3.0 yuan, mu cost nearly 2,000 yuan, average annual 10 mu. 30mm thick cement board can be used for 100 years, 1 square meter 5 yuan, the cost of nearly 3500 yuan per mu, average annual average of 35 yuan per mu. Both sides are not polished rough slate, 10mm thick, 1 square meter 15 yuan, mu cost 10000 yuan, can use the millennium, mu average of 10 yuan per year. All have very good sustainability. ☆ The economic conditions of ordinary farmer households are difficult to bear. They can only be promoted to richer, wealthier, and large grain producers, promoted to urban greening, ecological parks, and picking gardens, and promoted to special growers and improved breeders. Supported desert governance, severe land degradation and desertification control, land salinization treatment, severe soil erosion control, grassland desertification degradation treatment, treatment of severely afflicted areas, promotion of arid and semi-arid treatment areas, can also be sent to the front of ordinary farmers Garden planting promotion. Gradually develop with a small increase. The degree of universal development is about 50 to 100 years. Due to the current economic constraints, growers have insufficient understanding of hardboard coverage methods. The promotion in the early stage is very difficult and slow. The economic benefits to the growers can be obtained. The economic benefits can be obtained by using the cover method. The income, or loss of money, growers have further understanding of the cover method, start the mid-term promotion, later it will be faster, hard board resources in short supply, people will want to develop other materials hard board, as a substitute for hard board Materials, new cheaper and more durable alternatives have been developed, and the sustainability of agricultural planting has increased. ☆ On the current lack of fresh water resources in China, lack of food growth, increased soil erosion, land desertification, degradation, salinization, grassland desertification, degeneration, rodent pests, continuous reduction of land resources, agricultural pesticide residues, downstream aquatic pesticides With serious pollution and huge population pressure, we urgently need to come up with ways to control the land environment deterioration, water shortage, slow grain growth, and serious pesticide pollution. The closed-enclosed rigid planting methods are highly practical in these fields. . 5, completely closed hardcover planting method is a very simple method, but it solves many problems that countries can not solve so far, it is related to the future of the country, people, and even human survival.
