Problems solved by technology

[0004] 1. When the water and fertilizer integration technology of micro-sprinkler irrigation is applied to field crops, it is necessary to lay the micro-spray belt after the crops are sown, and roll up the micro-spray belt before harvesting. The labor cost is high, the efficiency is low, and it is difficult to promote in a large area;
[0005] 2. The working pressure and flow of the micro-spray irrigation water source are easy to fluctuate and unstable, resulting in unstable irrigation uniformity and irrigation volume;
[0006] 3. Although the micro-sprinkler irrigation system is equipped with fertilization equipment such as Venturi fertilizer injector or proportional fertilizer suction device, it is difficult to achieve precise control of fertilization when the water pressure is unstable, and there are many operating procedures, farmers are generally unwilling to use it;
[0007] 4. The granular fertilizers used by farmers are prone to incomplete dissolution, which can easily cause clogging of the filter of the micro-sprinkler irrigation system. Water-soluble fertilizers are expensive and difficult for farmers to accept
[0008] In summary, according to the characteristics of decentralized management of field production plots, in view of the problems of time-consuming and labor-intensive laying of micro-spray belts, inaccurate fertilizer ratios, high input costs of water and fertilizer integration systems, low use efficiency, and inability to flexibly apply to different fields, etc., There is an urgent need to invent a mobile micro-sprinkler irrigation water and fertilizer integrated management system and its control method, which is used for the placement and rewinding of micro-spray belts for wheat, corn and other field crops, the online precision distribution of multi-fertilizers, and the integration of micro-spray irrigation water and fertilizer. operation, which has important practical significance for improving the efficiency of water and fertilizer integration and increasing grain production
