Accurate fertilizing device for soilless culture

Abstract

The invention discloses an accurate fertilizing device for soilless culture. The device comprises a fertilizer storage drum and a water storage tank, wherein the fertilizer storage drum is used for storing high-concentration fertilizer stock solution; the water storage tank is used for storing clean water; a discharging port is embedded on the right side of the bottom of the fertilizer storage drum; a filtering mesh screen is embedded in the discharging port; a fertilizing tank is connected with the tail end of the discharging port through a rubber pipe; a water suction pump is fixed at the top on the left side of the water storage tank; a water outlet of the water suction pump is connected with a water inlet of the fertilizing tank through a rubber water pipe; a protecting cover is covered on the top of the fertilizing tank; circular guide pipes served as the water inlet and a fertilizer inlet are respectively embedded on left and right sides of the upper surface of the protecting cover; a stirrer is penetrated through the middle of the protecting cover; a pump flow rating pipe is arranged at the bottom on the front side of the fertilizing tank; a head valve is arranged at the water outlet of the pump flow rating pipe; a fertilizing pump is arranged at an output port of the head valve; an injection nozzle is connected with the output port of the fertilizing pump. The accurate fertilizing device for soilless culture is capable of realizing the quantitative accurate fertilizing operation and increasing the fertilizing uniformity and is simple and convenient in operation.

Description

technical field [0001] The invention relates to the field of agricultural equipment, in particular to a precise fertilization device for soilless cultivation. Background technique [0002] Soilless cultivation uses light materials such as peat or forest leaf humus and expanded vermiculite as the seedling substrate to fix the plants, allowing the plant roots to directly contact the nutrient solution, and adopts the modern seedling technology of mechanized precision seeding for one-time seedling formation. The selected seedling tray is divided into compartments, sow one seed in one compartment, and one plant in one room for seedlings. The root system of the seedlings and the substrate are intertwined with each other. nursery. In soilless culture, fertilization operation is very critical. However, the existing fertilization devices generally use high-pressure cleaners, plant protection pesticide application equipment, pipeline centrifugal pumps, etc., and their performance pa...

AI Technical Summary

Problems solved by technology

However, the existing fertilization devices generally use high-pressure cleaners, plant protection pesticide application equipment, pipeline centrifugal pumps, etc., and their performance parameters cannot meet the requirements of precise fertilization, resulting in poor fertilization uniformity and low water and fertilizer utilization, which affects crop yield and quality.
