The soil moisture of farmland also has a certain improvement effect on the adjustment of the conflict between the increasing water demand and the scarcity of water resources. It is of great significance to develop and utilize water resources, to bring into play the benefits of irrigation projects, and to achieve water saving goals. Therefore, the monitoring of soil moisture content has a very important guiding role in the development of China's agriculture and can promote the sustainable development of China's agriculture. Strategy implementation. The monitoring effect of wireless moisture and drought management systems on soil moisture content is obvious to all.
The commonly used soil moisture forecasting methods include: a simple measurement method for soil water consumption rate, a statistical correlation method for influencing factors such as soil moisture, temperature, and precipitation, and a water balance method. Because these methods do not solve the long-term, day-to-day continuous calculation of soil moisture, and they also depart from the degree of soil water deficit, ie, the drought index, they are not ideal in practical applications. Through the analysis of the law of public opinion index of farmland irrigation and drainage experiment stations through the wireless public opinion and drought management system, the drought indices of different soils can be obtained. Once drought occurs, the calculation model can be used to predict the soil of the future date of the forecast. The situation of water receding and the trend of forecasting the increase of drought when drought conditions are eased or lifted can be monitored at any time if the soil moisture is continuously calculated. When drawing a large number of observation points at the same time, the public opinion index is plotted on the floor plan, and the distribution and trends of the public opinion or drought situation on the surface can be grasped at any time.
Through the monitoring and analysis of wireless public opinion and drought management systems, the public opinion forecasting and drought indicators integrated/practical public opinion forecasting method 0 is effective in solving single station and regional public opinion forecasting and irrigation forecasting in the current public opinion forecasting method, so as to formulate drought prevention in time. Disaster reduction countermeasures provide a better method for scientific basis. The use of existing precipitation observation point data to calculate the soil moisture changes in the root development layer not only solves the problem that the traditional public opinion forecasting method cannot continuously calculate the grievance over a long period of time, but also makes up for the direct interassay method. The lack of influence of soil variability and spatial distribution of precipitation on soil moisture was reflected.
