Water, fertilizer and pesticide integrated system based on drip irrigation head and control method of system

Abstract

The invention discloses a water, fertilizer and pesticide integrated system based on a drip irrigation head and a control method of the system. The water, fertilizer and pesticide integrated system based on the drip irrigation head comprises a drip irrigation head system, a solid dissolution injection system and a liquid injection system, wherein the drip irrigation head system comprises a main irrigation pipeline provided with a first connecting part and a second connecting part sequentially in the water outlet direction, the solid dissolution injection system comprises a spraying, washing and dissolving tank with an opening at the upper part, a spray head is correspondingly arranged above the opening of the spraying, washing and dissolving tank and connected with the main irrigation pipeline at the second connecting part through a water spraying and supplying pipeline, and a spraying tank filtering net is paved in the spraying, washing and dissolving tank; a dissolving solution collecting tank is arranged below the spraying, washing and dissolving tank and connected with the main irrigation pipeline in the first connecting part through a dissolution liquid injection pipeline. Fertilizer application, pesticide application and drip irrigation are really integrated, so that the drip irrigation head becomes a part of the water, fertilizer and pesticide integrated system.

Description

technical field

[0001] The invention belongs to the technical field of agricultural fertilization, pesticide application and irrigation, and in particular relates to an integrated system of water, fertilizer and medicine based on a drip irrigation head and a control method thereof. Background technique

[0002] With the development of agricultural modernization, the water-fertilizer (pesticide) integration technology based on drip irrigation has been recognized in the vast rural areas. The water-fertilizer (pesticide) integration technology can realize water-saving irrigation and realize the comprehensive coordination and integrated management of water and nutrients. , has the advantages of improving crop yield and quality, strong adaptability to terrain and geology, and being able to maintain water and soil, and has become an important symbol of modern agriculture. However, the organic integration of water and fertilizer (pesticide) integration is not perfect at present, an...
