Abstract

The invention belongs to the technical field of planting industry informatization and provides a site layout method and a system for testing the corn planting environment. The method comprises the steps of acquiring the region data of a to-be-layout region; according to the region data, subjecting the planting environment of the to-be-layout region to grid division and clustering division so as to obtain a division result; based on a preset space stratified sampling model and a sampling precision, obtaining test sites of a required minimum number for each region in the division result; based on a preset space balance sampling algorithm, conducting the layout for test sites of the minimum number. In combination with planting environment indexes for the to-be-layout region, the analysis is conducted. Based on the spatial clustering and space stratified sampling theory, the layout of corn multi-environment test sites can be determined. Therefore, the test site layout reasonability is improved.

Description

technical field [0001] The invention belongs to the technical field of planting industry informatization, and in particular relates to a method and system for the layout of a corn planting environment test site. Background technique [0002] my country has a vast territory, and the planting range of corn is extremely wide, but it is mainly distributed in the northeast, north and southwest mountainous areas, roughly forming an obliquely long zone from northeast to southwest. The sown area of ​​corn planting in this zone accounts for It occupies more than 80% of the area and plays a pivotal role in food safety and national economic development. Therefore, with the continuous development of planting technology and the implementation of the green channel for variety approval, more and more breeding units have established a large number of corn variety experiment bases across the country to test corn varieties. [0003] The multi-environmental testing of crop varieties is one of ...
