Problems solved by technology

[0003] Due to the small amount of the existing special fertilizer liquid, it is easy to have residual pipes. Therefore, in most cases, the fertilizer liquid is mixed with clean water in advance, and then added. This method still has some losses

Abstract

The invention discloses a precision agricultural greenhouse fertilizer proportioning device. The precision agricultural greenhouse fertilizer proportioning device comprises a purified water metering hopper and a fertilizer liquid metering hopper. In the actual mixing process, a metering pump is used for achieving the amount control, and a three-way electrometric valve sends water into the purifiedwater metering hopper and a subordinate water tank in an adjusting manner; clean water sent into the purified water metering hopper first is mixed with an external agent and is sent to a stirring box, while water in the subordinate water tank is sprayed out from a spray head under the pressurized conveying effect of a booster pump, and at the moment, the inner wall of the purified water meteringhopper is washed, so that the conditions of adhesion and waste of the external agent can be avoided; overall, through adoption of single water injection, effective waste prevention can be achieved, the effect is excellent and the operation is easy; then, compressed air is ejected from the spray head, and a high-speed flowing airflow can quickly blow off mixed liquid accumulated on the inner surface of the purified water metering hopper, so that rapid treatment to the accumulated water can be performed, thus the residual condition of the mixed liquid on the inner wall is avoided and the overallspeed efficiency is higher.

Description

technical field [0001] The invention relates to the field of agriculture, in particular to a device for accurately proportioning fertilizers in agricultural greenhouses. Background technique [0002] Fertilization refers to the agricultural technical measures of applying fertilizers to the soil or spraying them on plants to provide the nutrients needed by plants and maintain and improve soil fertility. The main purpose of fertilization is to increase crop yield, improve crop quality, fertilize soil and improve economic benefits. Therefore, rational and scientific fertilization is one of the main means to ensure food security and maintain sustainable agricultural development. The main basis for fertilization is soil fertility level, crop type, target yield, climate environment and fertilizer characteristics, so as to select the appropriate fertilizer, estimate the amount of fertilizer required, and determine the time and mode of fertilization. According to different fertiliz...
