Due to the influence of geography and climatic factors, the irrigation depth of Hetao irrigation district in Yinshan Mountain in the north is different from that of groundwater, and the spatial and temporal distribution of soil moisture content is also more complicated. The deployment of wireless public opinion and drought management systems in irrigation areas is an important means of accurately grasping information on soil moisture in irrigation areas and is also a necessary measure for the long-term accumulation of basic data for irrigation areas.
The establishment of wireless public opinion and drought management system in irrigation areas is one of the important contents of modern large-scale water conservancy informatization construction. It is also an important indicator to measure irrigation management level in irrigation areas. According to the analysis of soil moisture and drought data, the law of temperature, ground temperature, soil moisture content and other agricultural factors in the irrigation area can be timely reflected, and the Irrigation District Public Bulletin can be issued regularly to determine the crop sowing time, forecasting water diversion time, and water diversion amount. The important guiding value will also produce good economic and social benefits.
The main technical indicators include meteorological conditions, soil physical properties, soil moisture status, crop types and growth and development status, and groundwater level. Meteorological observation elements include precipitation, air temperature, atmospheric pressure, humidity, wind speed, surface evaporation, ground temperature, and sunshine. The physical characteristics of the soil are expressed by the texture of the soil, the structure of the soil, the specific gravity of the soil, the dry weight of the soil, and the porosity of the soil. The soil moisture constant is an important indicator of soil moisture characteristics. It mainly includes saturated water content, field water holding capacity, withered water content, and appropriate water content in different crop growth periods. While observing the soil water content, the sowing date of the crop, the growth period of the crop, and the growth and development of the crop were observed. The moisture status of the crop is represented by the grading of pupa, soil, normal, water shortage, and drought. The change of shallow groundwater level and groundwater depth is one of the important factors affecting the soil moisture content change. Groundwater observation elements include groundwater level, groundwater depth, groundwater temperature, and groundwater quality.
Through the monitoring and management of wireless public opinion and drought management systems, scientific irrigation systems can be formulated according to the appropriate soil moisture content at various growth stages of various crops to guide local agricultural production and adjust farmers according to local meteorological, groundwater, and inflow conditions. Planting structure, reasonable planting, reasonable irrigation, to achieve the purpose of water conservation and efficiency. Its economic and social benefits are obvious.
