Problems solved by technology

Taking wheat as an example, both traditional sowing and drilling methods have a large degree of randomness; for example, some seeds will gather in a small area, while other areas are sparsely distributed; or because the plants are too dense, it is impossible to accurately identify individual plants and plant position; or differences in sowing depth due to drill versus broadcast, can also affect post-emergence individual size

Embodiment 1

[0022] like image 3 shown, each 100m 2 10cn 2 After meshing, then, for 10cn 2 Each grid is encoded, that is, horizontal encoding (1, 2, 3, 4, 5, 6, 7, 8, 9...i) and vertical encoding (1, 2, 3, 4, 5, 6, 7, 8, 9...j), wire rope, plastic and iron grids can be used for the grid. The position of the grid is determined by each grid code (i / j). Because the present invention relates to the mixed sowing of two varieties, the grids of Zhongmai 175 and Xiping No. 1 are represented by "Z" and "X" respectively.

[0023] for image 3 a (Zhongmai 175 : Xiping No. 1 = 3 : 0) is the unicasting of Zhongmai 175, with Zhongmai 175 as the target variety, and the four nearest neighbor grids up, down, left, and right are target varieties, all of which are Zhongmai 175 ;

[0024] for image 3 b (Zhongmai 175 : Xiping 1 = 2 : 1), half of the four nearest neighbors of the target variety Zhongmai 175 are the same (two Zhongmai 175 and two Xiping 1); the target variety Xiping 1 No. The four...

Abstract

The invention discloses a uniform grid positioning seed sowing method based on crop ecology experiments. The method comprises the following steps: 1) laying out small cell seedling beds; 2) customizing and laying grids; 3) encoding the grids, and confirming a seed sowing scheme; 4) sowing seeds into the grids; 5) thinning seedlings after seedling emergence; 6) carrying out sampling. By adopting the method, positions of individual plants can be accurately positioned through the grids, seeds can be uniformly sown, distances and seed sowing depths of individual seedlings of wheat can be determined, and advantages of uniform and equal seedling distances, uniform individual sizes and accurate individual plant positions after wheat seedling emergence are achieved. The method disclosed by the invention is easy to operate, provides a scientific basis for studying interactions of individuals in a crop population and relationships of population behaviors and studying interactions of individual plants and ecological study on dense planting plants, and has popularization values.

Description

technical field [0001] The invention belongs to an ecological experiment method and mainly relates to the field of crop ecology. Specifically, it refers to an experimental method for studying the interaction between individuals and group performance (yield) by planting crops in grid cells divided in the field, and through the precise correspondence between crop varieties and the position of the grid cells. Background technique [0002] Crop production is a population process, and the population is composed of several individuals, and there are differences in size. Studying the relationship between individual interactions and group performance in crop populations is the core and hot topic of ecological research. In a dense planting environment, crop individuals gather together, and due to the competition for resource acquisition, they are inevitably affected by neighboring individuals. For the aboveground part, it competes for light resources by adjusting the plant type; wh...
