Greenhouse water and fertilizer integrated intelligent irrigation management and control device

Abstract

The invention discloses a greenhouse water and fertilizer integrated intelligent irrigation management and control device, and belongs to the technical field of agricultural automation equipment. Thegreenhouse water and fertilizer integrated intelligent irrigation management and control device is formed by connecting a blending box, a PLC control system, a water pump, a microcomputer system, an irrigation nozzle and a sensor group, information of an environment in a greenhouse is acquired through the sensor group, relevant information is input into the microcomputer system, the microcomputersystem analyzes data, according to a complex and interlaced database formed by combining soil and facility fruit and vegetable varieties in various regions, an optimal water and fertilizer proportionirrigation solution is decided, water and fertilizer are evenly mixed in the blending box according to the provided water and fertilizer liquid preparation solution, the proportioned water and fertilizer are conveyed to an irrigation spray head through a water pump, therefore the purpose of crop fertilization is achieved, in an implementation process, the microcomputer system displays informationsuch as a crop growth state, the temperature, the liquid level, the PH value and the EC value in real time according to the environment in a greenhouse plant factory, the proportion irrigation strategy is changed, and therefore the purposes of optimized regulation and control and fertilizer saving and efficiency improvement of greenhouse plant intelligent control water and fertilizer implementation operation are achieved.

Description

technical field [0001] The invention belongs to the technical field of agricultural automation equipment, and relates to an intelligent irrigation control device, in particular to an intelligent irrigation control device integrating water and fertilizer in a greenhouse. Background technique [0002] Water and fertilizer integration technology is an agricultural technology that integrates irrigation and fertilization. According to the soil nutrient content and the characteristics of the fertilizer requirements of the crop species, the water and fertilizer are irrigated in proportion to achieve the purpose of high nutrient utilization. However, in the actual application process, multiple factors such as soil structure, facility environment, seasonal season, and climate in greenhouses in different regions have an impact on the water and fertilizer required for crop growth, and it is difficult to determine the water and fertilizer ratio required by crops based on experience.

However, in the actual application process, multiple factors such as soil structure, facility environment, seasonal season, and climate in greenhouses in different regions have an impact on the water and fertilizer required for crop growth, and it is difficult to determine the water and fertilizer ratio required by crops based on experience.

In addition, artificial ratio irrigation will lead to precipitation of water and fertilizer, which will affect the effect of fertilization, and there is also the problem of excessive fertilization
