Soil moisture, one of the main resources of agriculture, has a very serious limitation on the development of agriculture and directly affects the growth of crops. In order to maximize the water use efficiency of the farmland and ensure the crop yield, it is necessary to take the appropriate agricultural technical measures without losing time. This premise is to be able to grasp the laws of soil moisture changes. For the assessment of soil moisture resources required for the growth of moving wheat, a soil moisture monitoring system can be established to determine the future changes in soil moisture.
Farmland soil moisture is influenced by meteorology, crops, and soil factors, and has obvious temporal and spatial distribution patterns. We have selected ten-day mean air temperature, precipitation, sunshine hours, average wind speed, evaporation, and surface temperature to measure and analyze In addition to the positive correlation of precipitation, the rest is negatively correlated, indicating that the greater the precipitation, the greater the soil moisture, and the higher the temperature, the more abundant the sunshine, the greater the average wind speed, the greater the evaporation, the higher the surface temperature. The soil moisture is smaller. This monitoring method is cumbersome and error-prone. Therefore, the application of soil moisture monitoring system is very convenient and effective.
After the completion of the soil moisture monitoring system, it is no longer subject to the date of measurement, and it can provide timely timely soil moisture for the leaders at all levels. According to this, it can be determined when the winter wheat needs to be irrigated during growth, and under the condition of ensuring normal water consumption of winter wheat, To optimize irrigation to save water resources and increase water use efficiency. At the same time, we can have a more detailed understanding of the water supply during the whole growing period of winter wheat. Especially in recent years, the drought in Liaocheng City has been aggravating, and understanding the supply and demand of winter wheat soil moisture can provide a reliable reference for drought resistance. In the local agricultural production and service work, there will be obvious economic and social benefits. At the same time, it will also play an important role in the usual business work, especially during the winter when the survey is stopped, because there is no public information, it often affects services. Quality, using this system can generally understand the changes in winter soil moisture.
In addition to predicting changes in soil moisture content, the soil moisture monitoring system model can also combine the requirements of winter wheat for moisture and give a qualitative review of appropriate, drought, and over-wetness as a monitoring system for crop moisture conditions. This has a very important guiding role in improving the yield of winter wheat and improving the utilization of soil moisture, and it is bound to be the necessary system for the development of precision agriculture in the future.
