Method and device for intelligently controlling precision irrigation and fertilization

Abstract

The invention relates to a method and a device for intelligently controlling precision irrigation and fertilization. The method and the device have the advantages that intelligent control is applied to the field of water-saving irrigation by the aid of the method and the device, so that the problem of high labor and material consumption required by manual operation on water-saving irrigation systems can be solved; fertilizers are applied to crops by the aid of an intelligent control system according to soil types, species of the crops and growing periods of the crops, and accordingly the method and the device are favorable for improving the fertilization precision and saving fertilizers; the fertilizers flow to locations near root systems of the crops along with water, accordingly, the method and the device are favorable for preventing deep-layer loss of the fertilizers, the fertilizer efficiency can be improved, the yield of the crops can be increased, underground water can be prevented from being polluted by the fertilizers and chemical agents, and the problem of agricultural non-point source pollution can be solved.

Description

technical field [0001] The invention relates to an intelligent control method and device for precise irrigation and fertilization. Background technique [0002] As a key factor of modern intensive irrigated agriculture, integrated irrigation and fertilization technology originated from the development of soilless cultivation, and mainly progressed with the development of irrigation technology. Irrigation and fertigation is an organic combination of irrigation and fertilization. With the help of a new irrigation system, fertilizers are formulated into fertilizer solution and input to the root soil of crops at the same time as irrigation, so as to achieve precise control of irrigation water, fertilization amount and time, and significantly improve irrigation water resources and Fertilizer utilization efficiency simultaneously increases crop yields. [0003] my country's irrigation and fertilization integration technology began with the introduction of drip irrigation technolo...

AI Technical Summary

Problems solved by technology

From the perspective of field application, the management level of my country's irrigation and fertigation technology system is relatively low, lacking a more intelligent and precise irrigation and fertigation control system; Insufficient; the research and development of special fertilizers for irrigation and fertilization has just started, and the equipment cannot be adapted to ordinary fertilizers, which is prone to problems such as pipeline blockage; the quality of some micro-irrigation equipment products, especially the first supporting equipment, is still comparable to that of similar foreign advanced products. There is a large gap, and the normal service life is short
