Device and method for regulating and controlling growth of sand culture tomatoes through water and fertilizer coupling

Abstract

The invention discloses a device and method for regulating and controlling growth of sand culture tomatoes through water and fertilizer coupling, and relates to the technical field of agricultural irrigation. The fertilizer barrel is fixed on the wall body, is positioned on one side of the water pump and is used for containing liquid fertilizer; one end of the water inlet pipe is installed at an input port of the water pump, the other end of the water inlet pipe is installed on a water supply system, the side wall of the water inlet pipe is communicated with a fertilizer barrel through a fertilizer pipe, and a control valve is fixed to the fertilizer pipe and used for controlling the inflow amount of the liquid fertilizer; one end of the water outlet is mounted at an output port of the water pump, and an irrigation dropper is fixed at the other end; the filtering assembly is mounted at the position, close to the water pump, of the water outlet and used for filtering the irrigation water and the liquid fertilizer.

Description

technical field [0001] The invention relates to the technical field of agricultural irrigation, in particular to a device and method for controlling the growth of sand-cultivated tomatoes by coupling water and fertilizer. Background technique [0002] Water-fertilizer coupling is to promote rational coordination of irrigation and fertilization in terms of time, quantity and method according to different water conditions, so as to increase crop yield and improve quality. [0003] After filtering irrigation water and liquid fertilizer, the existing water-fertilizer coupling control device cannot discharge the filtered particulate impurities in time, causing them to accumulate on the filter plate, which affects the flow of irrigation water and liquid fertilizer, resulting in failure Sufficient supplementation of water and fertilizer to cultivated crops in time affects the growth of crops. [0004] In view of the above problems, the present invention provides a device and metho...

AI Technical Summary

Problems solved by technology

[0003] After filtering irrigation water and liquid fertilizer, the existing water and fertilizer coupling control device cannot discharge the filtered particles and impurities in time, causing them to accumulate in the filter plate On the other hand, it affects the flow of irrigation water and liquid fertilizer, which leads to the inability to replenish water and fertilizer to the cultivated crops in time, and affects the growth of crops.
