Crop field water consumption: The amount of water consumed by a crop during the entire growth period from the crop to the harvest. In mm or m3/acre. There are differences in plant water consumption under different water conditions. For areas with low water content, the field water consumption of the crop is not only the water demand of the plant, but the water consumption is the crop water requirement and leakage in areas where the moisture content is relatively abundant. Sum. The lack of water resources is now a common problem among colleagues. Most of the fresh water in the world is used for irrigation of farmland. Therefore, it is necessary to reasonably control the soil moisture content. The detection of soil moisture content can use the regular positioning of soil.

The zucchini has become one of the main cultivated vegetables in the solar greenhouse. The planting area of ​​the summer cucurbit in the greenhouse is second only to the cucumber in the melon vegetables. The control of the soil moisture content during the planting process can effectively increase the yield of the zucchini and use the agricultural environment. Monitoring stations to monitor the soil moisture and yield of summer squash found that when the soil moisture content was controlled within the range of 70% to 80%, the number of melons was the highest, the yield was the highest, and the water use efficiency was also the best. The relationship between soil moisture content and water consumption is also a certain relationship, the use of a regular positioning of soil moisture measuring instrument to control the soil moisture of summer squash, to control it in the following five conditions: 50 ~ 60%, 60 ~70%, 70~80%, 80~90%, and 90~100% were used to understand the water consumption under different soil moisture content. It was found that the water consumption of summer cucurbit in the solar greenhouse increased with the increase of water treatment level. That is, when the soil moisture content is 90~100%, the water consumption of the plant is the highest, and the water consumption of the soil moisture content between 50~60% is the lowest.
There is a difference between the lowest soil moisture content and the highest yield. Therefore, a relatively compromised point can be used during the planting process. In the experiment process, a regular positioning soil moisture meter can be used to conduct real-time measurements. The control and operation for the water-saving and high-yield measures accordingly.
