Comprehensive water, fertilizer and pesticide control system for facility agriculture and operation method of system

Abstract

The invention relates to the technical field of agricultural planting, in particular to a comprehensive water, fertilizer and pesticide control system for facility agriculture and an operation methodof the system. A field, a material mixing device, a filtering device and a spraying device are involved, the material mixing device is arranged on the top left side of the field, the left end of the material mixing device is communicated with the filtering device, and the right end of the filtering device is communicated with the spraying device; according to the system, by arranging a water pump,a sealing plate, a filtering box, a fixed ring, a filtering screen, a water-proof ring and the like, undissolved solid fertilizer particles can be filtered under the effect of the filtering screen, it is avoided that solid particles block a water dripping port, so that the irrigation and fertilizer application efficiency is influenced, and by arranging a spraying pipe, a connecting plate, an adjusting shell, an adjusting rod, a limit rod, a first spring and the like, crops can be sprayed with pesticide through a mist sprayer; the problem that a traditional water and fertilizer spraying devicecannot spray pesticide is solved, and the spraying height of the mist sprayer can be adjusted according to the height of crops.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, in particular to an integrated control system for water, fertilizer and medicine in facility agriculture and an implementation method thereof. Background technique [0002] Water and fertilizer integration technology refers to the new agricultural technology that integrates irrigation and fertilization. Water and fertilizer integration is to use the pressure system (or the natural drop of the terrain) to apply soluble solid or liquid fertilizers according to the soil nutrient content and the law and characteristics of crop types. , the blended fertilizer solution and irrigation water are supplied with water and fertilizer through the pipeline system, and are evenly and accurately transported to the root area of ​​​​the crops. At present, with the rapid development of agriculture, the requirements for fertilization, irrigation and spraying are gradually increasing. Therefore, for The...

AI Technical Summary

Problems solved by technology

[0003] Most of the agricultural water and fertilizer integrated control systems currently on the market are simple in structure and single in function. General field fertilization needs to apply fixed fertilizer or liquid fertilizer to the field according to different field needs. The existing fertilizer mixing device does not have the ability to fix It is a device for stirring fertilizer, and the stirring rod of the general stirring device is not easy to disassemble and maintain, and the solid waste is easy to be mixed with non-melting particles, and the fixed particles are easy to cause blockage of the liquid outlet, and the general fertilization and irrigation device does not have the function of spraying pesticides , it is not convenient for growers to use, therefore, in view of the above problems, a comprehensive control system of water, fertilizer and medicine in facility agriculture and its implementation method are proposed
