Abstract

The invention provides a water and fertilizer control method and system. The method comprises, according to the environment information and soil information of the area where a crop is planted as wellas the current growth stage of the crop, acquiring the amount of water demanded; according to the soil nutrition information of the area and the nutrient absorption characteristics of the crop, acquiring the amount of nutrition demanded of the crop in the current growth stage on the basis of a soil nutrient balance method; according to the amount of water demanded and the amount of nutrition demanded of the crop, irrigating and applying fertilizer to the crop. By analyzing and processing irrigation and fertilizer application data, the water and fertilizer control method can help automaticallymake irrigation and fertilizer application decisions with higher precision and scientific performance.

Description

technical field [0001] The invention belongs to the technical field of agricultural informatization, and in particular relates to a water and fertilizer management and control method and system. Background technique [0002] The development of modern agriculture requires high-level automation equipment to improve the level of planting. However, due to the increasing shortage of water resources, the increasingly serious problems of soil, chemical fertilizers, and environmental pollution, the increasing labor costs, and the increasing energy consumption, the solution to these problems requires scientific water and fertilizer regulation technology. [0003] At present, there are various forms of irrigation and fertilization for field crops in large parks, most of which use simple automatic irrigation and fertilization equipment. The amount of irrigation and fertilization is still determined based on extensive experience or regular quantitative irrigation, lacking scientific bas...
