Abstract

The invention relates to the technical field of agriculture, and provides a salinized soil water and fertilizer strategy acquisition method and system, a storage medium and electronic equipment, and the method comprises the steps: obtaining a preset value of soil conductivity used for representing the soil salinization degree at a preset time point, and determining a target value of each parameter associated with soil salinization at the preset time point; and inputting the preset value and all the target values into a trained reverse residual neural network to obtain a salinized soil water and fertilizer strategy corresponding to the soil with the soil conductivity being the preset value. The constructed reverse residual neural network can better fit an actual application scene of irrigation and water conservancy, the reverse residual neural network can directly simulate and optimize according to the target soil salinity corresponding to the preset value of the soil conductivity to obtain a salinized soil water and fertilizer strategy, the model precision is high, the simulation requirement can be met, a powerful technical means is provided for optimizing a field irrigation and fertilization strategy, and the analysis efficiency is improved.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a method, system, storage medium and electronic equipment for obtaining a water and fertilizer strategy for saline soil. Background technique [0002] Saline soil is one of the main low-yielding soil types in my country, and its productivity level is closely related to soil quality. Improper use will quickly lead to soil degradation and productivity reduction. In salinized irrigation areas where fresh water resources are scarce, the use of brackish water is inevitable, but excessive use will aggravate soil salinization. It has become an urgent task in the field to seek an irrigation system for safe use of brackish water. Drip irrigation with brackish water is a widely used irrigation method with high water-saving efficiency. The irrigation method of "drip irrigation" can reduce the influence range of brackish water on soil salinity distribution. In addition, a reasonable a...

Problems solved by technology

These traditional data analysis methods have been widely used for a long time. Unfortunately, such methods assume a linear relationship between indicators, and this assumption is difficult to hold in real situations.

This kind of method cannot analyze the nonlinear relationship between indicators, which will lead to the artificial loss of some unknown features, which limits the comprehensiveness of the analysis to a certain extent, especially the mechanism of action of brackish water and fertilizers on saline soil is more complicated, The linear analysis method cannot obtain the complex characteristics of water, fertilizer and salt; in addition, the traditional model simulation method takes irrigation and fertilization as the input terminal, simulates and predicts the dynamics of soil water and salt, and combines the dynamics of soil water and salt with further multiple screening analysis to obtain the optimal water and fertilizer. Analysis efficiency is low
