Intelligent irrigation and fertilization control method and system based on Internet of Things

Abstract

The invention belongs to the technical field of water and fertilizer integration, and particularly relates to an intelligent irrigation and fertilization control method and system based on the Internet of Things. The controller is fixedly connected to the top of the fixed seat; the water pump is fixedly connected to the top of the fixed seat, and the water pump is used for conveying irrigation water; the mixing pipe is fixedly connected to the top of the fixed seat, the mixing pipe is fixedly communicated with the water pump and the fertilizer liquid pump respectively, the mixing pipe is used for mixing irrigation water and fertilizer liquid, and the grinding mechanism is arranged, so that the fertilizer can be ground when being caked, and the granular fertilizer can also be ground; when the fertilizer is diluted and dissolved, the dissolution rate of the fertilizer is increased, the fertilizer is dissolved uniformly, the fertilization quality of crops is improved, and meanwhile, the situation that the fertilizer which is not completely dissolved enters a pipe network and blocks the pipe network can be prevented.

Description

technical field [0001] The invention relates to the technical field of irrigation and fertilization integration, in particular to an intelligent irrigation and fertilization control method and system based on the Internet of Things. Background technique [0002] The irrigation and fertilization system uses the pressure system to mix the soluble solid or liquid fertilizer, according to the soil nutrient content and the fertilizer requirements and characteristics of the crop type, and the mixed fertilizer solution together with the irrigation water to supply water and fertilizer through a controllable pipeline system. After the water and fertilizer are mixed together, drip irrigation is formed through pipes and drippers, which evenly, regularly and quantitatively infiltrate the crop root development and growth area, so that the main root soil always maintains loose and suitable water content. [0003] Irrigation and fertilization system can be designed according to the fertili...

AI Technical Summary

Problems solved by technology

[0003] The irrigation and fertilization system can be designed according to the characteristics of different crops' fertilizer needs, soil environment and nutrient content, crops' water needs in different growth periods, and the law of fertilizer needs in different growth periods, and the water and nutrients are regularly and quantitatively provided directly in proportion For crops, the existing irrigation and fertilization system needs to add granular fertilizer to the fertilizer tank for dilution and dissolution before the irrigation and fertilization work. If there is agglomeration of fertilizer, it will affect the dissolution rate, and it is easy to mix the fertilizer unevenly, and It is not convenient to control the amount of fertilizer used, which makes it easy to have too much fertilizer or overwatering, which will affect the fertilization effect of crops
