Facility agriculture intelligent water and fertilizer integrated control system and control method

Abstract

The invention discloses a facility agriculture intelligent water and fertilizer integrated control system and a control method. The control system comprises a four-layer framework of a planting layermodule, a control layer module, a local management layer module and a remote management layer module; and the control layer module, the local management layer module, the remote management layer module and the planting layer module are electrically connected with each other. The control system comprises the following steps: determining a precise fertilizer mixing control algorithm; determining thedynamic correlation between the atmospheric indexes of the soil plants, and establishing an optimal water and fertilizer regulation and control mode mathematical model; and researching and designingthe facility agricultural water and fertilizer integrated system. According to the control system and the control method in the invention, the utilization coefficient of irrigation water and the effective utilization rate of the fertilizer can be improved, wasting of resources, ecological degradation and environmental pollution are reduced, the sustainable development of agriculture is guaranteed,and high-yield, high-quality, efficient, ecological and safe modern agriculture development is realized.

Description

technical field [0001] The invention relates to the technical field of facility agriculture, in particular to an intelligent water and fertilizer integrated control system and control method for facility agriculture. Background technique [0002] The integration of water and fertilizer is a new technology of high-efficiency water-saving and fertilizer-saving agriculture. It mainly uses irrigation equipment to supply water and nutrients to crops in a uniform, accurate, timely and quantitative manner according to soil characteristics and crop growth laws. In the existing technology, there are still problems in the relationship between water and fertilizer and crop yield and quality, water and fertilizer control system equipment, water and fertilizer process control technology, etc., which are not suitable for the development of modern facility agriculture, which has affected the popularization and use of water and fertilizer integration technology. At the same time, my country'...
