Abstract

The invention provides an irrigation decision-making system and method based on an agricultural system model, and belongs to the technical field of agricultural irrigation decision-making. The system comprises a meteorological data interface, a meteorological database, the calibrated agricultural system model, a calibrated agricultural system model base, an irrigation decision-making algorithm, an irrigation decision-making algorithm base and an irrigation control system, wherein the meteorological data interface is used for providing meteorological data needed for calculation for the calibrated agricultural system model, the calibrated agricultural system model is used for conducting calculation according to meteorological conditions to obtain crop growth information and soil and crop moisture conditions, the irrigation decision-making algorithm is used for judging whether irrigation is conducted or not and calculating the irrigation amount according to the model calculation result, and the irrigation control system is used for conducting irrigation according to the irrigation amount calculated by the irrigation decision-making algorithm. The irrigation decision-making system and method based on the agricultural system model overcome the defects of an existing irrigation decision-making system and method, an accurate irrigation plan is made without installing field sensors, and a future irrigation plan and the corresponding irrigation effect can be predicted.

Description

technical field [0001] The invention belongs to the technical field of agricultural irrigation decision-making, and in particular relates to an irrigation decision-making system and method based on an agricultural system model. Background technique [0002] At present, my country's agricultural irrigation mode is relatively backward, and the traditional irrigation mode based on experience is still widely used. Under this irrigation mode, not only the utilization efficiency of water resources is low, but water resources are wasted and the problem of water shortage in agricultural irrigation is exacerbated. Moreover, Excessive irrigation water will cause deep seepage and loss of nitrogen and phosphorus, causing secondary salinization of soil and other problems, which not only affects the normal growth of crops and reduces crop yield, but also pollutes groundwater and causes environmental and ecological problems. On the other hand, crop growth requires a certain amount of water,...
