Abstract

The invention provides an integrated automatic control system for underground dripping irrigation water, fertilizer and medicine and a method thereof, which belongs to the water saving irrigation field, wherein, the system comprises a data input system, a sensor device, a master control device and an output device; the method comprises the following steps: A. initialization data of crops is set; B. a plurality of parameters related to cropland irrigation are acquired; C. a plurality of acquired parameters related to cropland irrigation are combined with the initialization data, and irrigation decision-making software is used for analysis and calculation; D. instructions are executed according to analysis and calculation results. The invention utilizes modern information technologies to grasp mutation of cropland environmental parameters, and has the advantages of high automatic control degree of scientific irrigation and drip irrigation and effective lightening of labor intensity.

Description

technical field [0001] The invention relates to the field of water-saving irrigation, in particular to an automatic control system and method for the integration of underground drip irrigation water, fertilizer and medicine. Background technique [0002] Water, fertilizers and pesticides are the three most important factors indispensable in agricultural production, and they are closely related to the growth, development and final yield of crops. Especially in modern agriculture, as people's requirements for crop yield and quality continue to increase, it is far from enough to only consider a single factor in water, fertilizer, and medicine. The relationship between the three must be fully considered to achieve water quality. The joint scheduling and integrated control of fertilizer, fertilizer and medicine can achieve high and stable crop yield. [0003] Underground drip irrigation is currently recognized as one of the most efficient water-saving irrigation technologies in ...
