Crop water fertilizer integrated control system and control method thereof

Abstract

The invention relates to a crop water fertilizer integrated control system. The crop water fertilizer integrated control system comprises a main controller, a water pump and a fertilizer pump which are controlled by the main controller to be opened, a plurality of node controllers which are controlled by the main controller and are distributed in crop planting regions, and an electric control valve which controlled by the node controllers and is arranged on a conveying pipeline, and further comprises a water fertilizer mixing device, a water tank and a storage module. With the adoption of the technical scheme, the storage module is arranged so that optimal water fertilizer rules for different crops (such as vegetables, tomatoes, cucumbers and strawberries) under different growth periods are constructed in the whole system; the main controller is used for controlling timing, quantification and fixed frequencies of the water pump and the fertilizer pump according to the rules; different modes of a fertilizer and water mixing device are set so that the crops have relatively excellent water supplying amount and fertilization amount at different growth phases; and the water and fertilizers can be conveyed to roots of the crops, and the synchronization of space apposition and time intensity of roots, the water and the fertilizers is realized.

Description

technical field [0001] The invention relates to the technical field of irrigation automation control, in particular to a crop water and fertilizer integrated control system; at the same time, the invention also relates to a control method of the crop water and fertilizer integrated control system. Background technique [0002] With the development of the new agricultural management system, how to reduce the use of water resources and increase the yield of crops in crop cultivation has become a new topic for agricultural development. At present, with the rapid development of modern information technology, it is possible to use modern information technology and intelligent equipment technology to realize agricultural water saving. For example, in the existing technology, foreign automatic control systems are mostly introduced, but these systems are expensive and not suitable for our country. production actually.

Problems solved by technology

At present, with the rapid development of modern information technology, it is possible to use modern information technology and intelligent equipment technology to realize agricultural water saving. For example, in the existing technology, foreign automatic control systems are mostly introduced, but these systems are expensive and not suitable for our country. actual production

In the 1970s, my country began to introduce irrigation and fertilization technology and carry out related experiments, but most of the research focused on academic or technology introduction, and insufficient consideration was given to the actual needs of crop water and fertilizer, which would still lead to waste of water resources and fertilizers, which could not meet the needs of crops. growth needs
