Multi-point Soil Moisture Monitoring System for Water Monitoring in Increasing Wheat Yield

Wheat production is a matter of great concern in the process of agricultural planting and development. There are many external factors affecting its yield. The first moisture condition is one of the important factors. In the long-term production process, the status of soil moisture during wheat growth was analyzed, and ways to increase water use efficiency were discussed from the aspect of farmland water regulation. Using multi-point soil moisture monitoring system to monitor soil moisture in wheat field, we can find that the water in the whole growth period mainly depends on the water storage in the soil before the winter, and the difference between the actual water consumption and the water demand is still relatively large, and often suffers from dryness. With early threats, supplemental irrigation is an important measure for the stabilization of yield and yield for the retention of wheat. The implementation of supplementary irrigation measures generally requires the use of a multi-point soil moisture monitoring system to monitor and understand the relevant conditions of soil moisture and make the most suitable irrigation method.

The monitoring of soil moisture using the multi-point soil moisture monitoring system was divided into seven treatments with an estimated amount of 75, 90, 120, 180, 225, and 270 mm. As the amount of irrigation increases, the production yield also increases. However, if the amount of irrigation exceeds a certain amount, the effect of increasing production is not obvious or slightly decreases. From the point of view of the efficiency of water irrigation per millimeter of irrigation, it generally decreases as the amount of irrigation increases. 'But a small amount of irrigation benefits are also low. Under the condition that the upper layer of soil is relatively dry, the depth of water infiltration is shallow, and it is easy to dissipate. With the deeper root system of wheat, the moisture of the supply cannot be fully absorbed by the crop. Therefore, the amount of irrigation is larger, the number of irrigation is relatively less, and the benefits are better. The irrigation time of dryland wheat is better, because the water content of wheat fields has been decreasing. The soil moisture is relatively high in early time, and the moisture can easily penetrate into the deep layer. On the one hand, water loss can be reduced. On the other hand, the deep layer water is more abundant and can be fully Crop absorption.

Through the analysis of monitoring results of soil moisture in wheat fields by multi-point soil moisture monitoring system, it can be found that in the early stage of wheat development, the water conditions are generally better, but the water dispersion is very strong, and it is very necessary to adopt conservation measures. For example, it is very important to cover loose soil. Effective measures. Moreover, using a multi-point soil moisture monitoring system to analyze the combination of soil moisture and yield after irrigation, it can be found that the wheat yield always increases with the increase of irrigation volume, and the early irrigation is more effective than the late irrigation, and the amount of irrigation is large each time. In some cases, the number of irrigations is relatively small, which will increase the moisture in the deep soil and reduce the loss of water.
