Water-fertilizer integrated irrigation system control method and water-fertilizer integrated irrigation system

Abstract

The invention relates to the technical field of agricultural production and provides a water-fertilizer integrated irrigation system control method and a water-fertilizer integrated irrigation system.The control method includes steps: S1, acquiring crop image information, soil information of a crop growth area and meteorological environment information of the crop growth area, and analyzing moisture supply conditions, fertilizer supply conditions and growth and development stages of crops on the basis of a ResNet-101 deep network model; step S2, controlling operation of a water-fertilizer integrated irrigation device on the basis of the moisture supply conditions, the fertilizer supply conditions and the growth and development stages. The control method has advantages that automatic, accurate and real-time determination of the moisture supply conditions, the fertilizer supply conditions and the growth and development stages of the crops can be realized aiming at different crops, and accordingly irrigation and fertilization as needed can be realized aiming at different crops, the problem of traditional experience based irrigation and fertilization decision making is effectively avoided, and real-time irrigation and fertilization as required can be realized.

Description

technical field [0001] The invention relates to the technical field of agricultural production, in particular to a control method for an integrated water and fertilizer irrigation system and an integrated water and fertilizer irrigation system. Background technique [0002] With the development of modern agriculture, high-level automation equipment has played an increasingly important role in promoting the improvement of planting industry. At present, the rapid development of my country's agriculture relies on the extensive use of water, fertilizers, and medicines. This method has caused an increasing shortage of resources and caused serious environmental pollution problems. my country currently consumes a lot of water for agricultural irrigation, and the amount of chemical fertilizer used far exceeds the internationally recognized safety limit for chemical fertilizer application. The excess chemical fertilizer enters the ecological circle with the water flow, causing eutrop...
