Embodiment 1

[0062] Embodiments of the present invention provide a method for predicting production based on water level buried depth values, such as figure 1 As shown, the processing flow of the method may include the following steps:

[0063]Step 101, obtaining the effective root zone buried depth value of the current crop.

[0064] In the process of agricultural production, the root zone of crops is an important part of nutrient uptake, and the root zone burial depth is different at different stages of the crop growth period. The root zone depth value refers to the height of the root zone end from the ground during the crop growth process. The water level depth value in the area where the crop is located has a great impact on the root zone of the crop, that is, the difference in the water level depth value will affect the growth environment of the crop. For example, if the water level is shallower, it will be flooded, and if the water level is deeper, it will be drought. Since crop wa...

Embodiment 2

[0112] An embodiment of the present invention provides a device for predicting production based on a water level buried depth value, the device comprising:

[0113] processor;

[0114] memory for storing at least one computer-executable instruction;

[0115] Wherein, the processor is configured as:

[0116] When executing the at least one computer-executable instruction, it is achieved that:

[0117] Obtain the effective root zone buried depth value of the crop at the current stage;

[0118] The waterlogging stress value and the drought stress value are obtained based on the burial depth of the effective root zone. The waterlogging stress value is the maximum water level burial depth value for crops free from waterlogging stress, and the drought stress value is the minimum water level for crops without drought stress during the growth period. Burial depth value;

[0119] Obtain the water level buried depth value for crops in the crop growing area;

[0120] Obtain the comp...

Embodiment 3

[0160] A computer-readable storage medium, wherein computer instructions are stored in the storage medium, and when the computer instructions are executed by a processor, the method described in Embodiment 1 is implemented.

Abstract

The embodiment of the invention discloses a method, a device and a computer storage medium for predicting yield based on a water level buried depth value, which belong to the technical field of agricultural production. The method includes: obtaining the effective root zone burial depth value of the crop at the current stage; obtaining the waterlogging stress value and the drought stress value based on the effective root zone burial depth value; coefficient and drought stress coefficient; the comprehensive stress index is obtained based on the water level buried depth value, drought stress value, waterlogging stress value, waterlogging stress coefficient and drought stress coefficient; the relative yield of crops is obtained based on the comprehensive stress index. By adopting the invention, the relative yield of the crop can be predicted more accurately based on the water level buried depth value of the area where the crop is located, while considering the influence of drought and waterlogging on the yield.

Description

technical field [0001] The invention relates to the technical field of agricultural production, in particular to a method, device and computer storage medium for predicting yield based on water level depth values. Background technique [0002] Agricultural waterlogging disasters and drought hazards are important factors restricting my country's grain production. With the intensification of climate extreme changes and the development of farmland drainage engineering technology, the new forms of drought-flood abrupt change and coexistence of drought and flood have further aggravated the loss of crop yield. Water production function is an effective tool to describe the effect of water surplus and deficit on crop yield. [0003] At present, the water production function that describes the profit and loss of water is to establish the functional relationship between waterlogging and yield through groundwater level and yield, and to establish the functional relationship between dr...
