Crop yield prediction method and system, storage medium and electronic equipment

Abstract

The invention relates to the technical field of agriculture, and provides a crop yield prediction method and system, a storage medium and electronic equipment. The method comprises the following steps: acquiring a specific value of each parameter related to the growth of a preset crop; and inputting the specific values of all the parameters into a progressive water-salt embedded neural network model to obtain a predicted value of the yield of the preset crop, wherein the progressive water-salt embedded neural network model comprises two layers of progressive causal relationships. According to the invention, the predicted value of the yield of the preset crop is obtained; the influence of different irrigation amounts and other climate and growth factors under a field straw deep burying condition on water-salt migration of soil and production benefits of the crop can be simulated; and tests show that the progressive water-salt embedded neural network model has relatively high precision, can effectively represent the comprehensive conditions of preset crop growth, namely the double-layer progressive causal relationship among each associated parameter, water and salt content migration in the soil and the yield of the preset crop, captures the internal dependency relationship of each parameter, and can be used for simulating the water and salt migration rule of an irrigated area.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a crop yield prediction method, system, storage medium and electronic equipment. Background technique [0002] Hetao irrigation area is an important grain production base in my country. Due to the sharp decrease in the amount of water diverted from the Yellow River and the imperfect management and utilization of water resources, problems such as secondary soil salinization in irrigated areas and agricultural non-point source pollution have become increasingly serious, restricting the sustainable and healthy development of agriculture in irrigated areas. How to improve saline land, improve efficiency and increase production is the main problem faced by irrigation districts. The distribution of water and salt in saline soil in irrigation areas affects the growth of crops. The study of water and salt migration can provide a theoretical basis for improving efficiency and yield...

Problems solved by technology

However, the solution of soil water movement and solute transport equations is often limited in the application of soil water and salt movement due to complex boundary conditions and numerous calculation parameters, and cannot simulate different irrigation amounts and other climate and growth factors under deep burial of field straw Effects on soil water and salt migration and crop production benefits
