According to the soil nitrogen, phosphorus and potassium detector test, under the same fertilizing amount, the salt content of plough layer soil produced by greenhouses is 4 times that of open field production. The fertilizer applied in greenhouses is not leached by rainwater. In addition to the loss of a small portion of the crop that was absorbed by the crop in the season, all unused nutrients were trapped in the soil, so the soil solution concentration was much higher than in the open field under the same fertilization amount, and due to the capillary As a result, soil moisture moves upwards, causing salt to concentrate in the cultivating layer, which results in salinization of the soil produced in the shed, and in cultivating vegetables and other horticultural crops in soils with high salinity content, due to the high osmotic pressure of the soil solution, the roots of the crop Absorption of soil moisture and nutrients is difficult, affecting the normal growth of crops, and severe rooting of seedlings.
According to the survey results of soil NPK indicator, there is a trend of increasing acidity in the soil produced in greenhouses. In particular, continuous production of greenhouses for many years, the residual nitrogen in the soil under the action of microorganisms, accumulated in a large amount of nitric acid, causing changes in the soil reaction. Practice shows that, after many years of continuous application of sulfuric acid, chlorination, and other physiological acidic fertilizers, the soil acidification is rapid, and the pH value drops significantly, which constitutes a soil obstacle for the cultivation of horticultural crops such as vegetables.
After detailed analysis of the soil nutrient in the greenhouse by soil NPK indicator, it also has some understanding of the measures for fertilization. The organic fertilizer produced in the greenhouse is preferably organic cellulose with a high cellulose and nitrogen ratio. The deep application of basal fertilizer and the limitation of topdressing shall be implemented. When chemical fertilizer is used as the base fertilizer, it is necessary to carry out deep application. It is better to apply chemical fertilizer and organic fertilizer on the surface and then plow till the most of the fertilizer is applied to the topsoil so as not to increase too much of the topsoil. Salt content. Composting is generally difficult to implement deeply, so it is necessary to strictly control the amount of use, rather use the method of increasing the number of top dressings, try to “eat less meals†to meet the vegetable's demand for nutrients.
Analysis of soil nutrient in horticulture greenhouse by soil NPK analyzer
In recent years, the development of greenhouses in various suburbs, especially in the outskirts of cities, has been very rapid. This is mainly because the production method is an intensive cultivation method with high input, high output, and high efficiency. However, during the greenhouse production process, the soil was covered with long-term membranes, direct sunlight and rainwater leaching were not obtained, and the plant structure was single. This led to the imbalance of nutrients in the soil and affected the yield and quality of horticultural plants. This is a problem that the greenhouse horticultural production is facing and needs to solve. Soil nutrient analysis in greenhouses can be analyzed using soil NPK detectors.
