Fertilization device with liquid fertilizer slow release function

Abstract

The invention relates to the technical field of agricultural fertilization, in particular to a fertilization device with a liquid fertilizer slow release function, which comprises a liquid storage tank, the bottom of the liquid storage tank is fixedly connected with an opening and closing mechanism, the bottom of the opening and closing mechanism is fixedly provided with a flow adjusting mechanism, a base is fixedly mounted at the bottom of the flow adjusting mechanism, and pesticide spraying mechanisms are connected to the left side and the right side of the base through rotating mechanisms. The bottom of the liquid storage tank is fixedly communicated with the opening and closing mechanism, a temperature regulation and control mechanism is connected with the opening and closing mechanism, and a stop plate is controlled to move by means of volume expansion or shrinkage of safe gas in a metal gas tank due to temperature change in cooperation with elastic support of a first spring, therefore, liquid fertilizer can be conveniently applied according to the external environment, the absorption efficiency of the liquid fertilizer can be prevented from being influenced by the application of the liquid fertilizer in high-temperature weather, the comprehensiveness of absorption of the released liquid fertilizer can be conveniently guaranteed, and the liquid fertilizer can be effectively prevented from being wasted without reasons.

Description

technical field [0001] The invention relates to the technical field of agricultural fertilization, in particular to a fertilization device with a slow-release function of liquid fertilizer. Background technique [0002] In the existing agricultural planting, in order to increase the production value of agricultural planting, the most direct way is to increase the production output of crops. In today's technology, the method of applying chemical fertilizers is usually used to increase the nutrients absorbed by crops, thereby improving crops. The production yield; in the prior art, according to the solid-liquid state of the fertilizer, it can be roughly divided into solid granular fertilizer and liquid fertilizer, wherein the liquid fertilizer can penetrate the soil and directly contact the roots of the crops, which greatly enhances the crops to the fertilizer. Absorption efficiency, so it is gradually promoted and used in today's agricultural planting; when liquid fertilizer ...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a fertilization device with a slow-release function of liquid fertilizer, to solve the problem that the existing equipment proposed in the above-mentioned background technology is difficult to slowly release the liquid fertilizer according to the external temperature conditions, which is not conducive to the full absorption of the liquid fertilizer. Easy to cause waste of liquid fertilizer
