System for automatically preparing irrigation and cyclic recycling type nutrient solution

Abstract

The invention relates to a system for automatically preparing an irrigation and cyclic recycling type nutrient solution. The system comprises a nutrient solution preparation groove, a detection pipeline, a pesticide adding pipeline, an irrigation pipeline, a reflowing pipeline and a water supplementing pipeline, wherein the detection pipeline is led out from the nutrient solution preparation groove and reflows to the nutrient solution preparation groove, and is used for detecting a nutrient solution in the nutrient solution preparation groove; the pesticide adding pipeline is used for enabling a fertilizer storage tank for storing a fertilizer and a pesticide storage tank for storing pesticide to be added in the nutrient solution preparation groove respectively, so that the addition of the fertilizer and the pesticide is realized; a venturi fertilizer injection device is arranged on the pesticide adding pipeline, and the irrigation pipeline is led out from the nutrient solution preparation groove and is connected to an irrigation region; the reflowing pipeline reflows into the nutrient solution preparation groove from the irrigation region; the water supplementing pipeline is connected with the nutrient solution preparation groove, and is used for supplementing water into the nutrient solution preparation groove. Compared with the prior art, the system is simple in structure and easy to control; the surplus nutrient solution can be cyclically utilized, water is saved, and the dosage of a chemical fertilizer is saved.

Description

technical field [0001] The invention relates to an irrigation system, in particular to a system for automatically preparing irrigation and recycling nutrient solution. Background technique [0002] With the rapid growth of population, agriculture plays an increasingly important role in social development. However, my country's basic national conditions are a large population and very little arable land per capita. Therefore, according to the current agricultural situation, the output of food crops can no longer meet the needs of population growth. Therefore, increasing the output of food crops per unit of arable land and reducing the The water resources, fertilizer resources, and pesticide resources required per unit of arable land are particularly urgent. There are many ways to increase the yield of food crops per unit area of ​​arable land and reduce the required water resources, fertilizer resources, and pesticide resources per unit area of ​​arable land, such as genetica...
