Abstract

The invention relates to the technical field of germplasm identification. The invention provides a field plot planting identification method for winter wheat seed purity. The field plot planting identification method comprises the following steps that (1), soil moisture water is watered on a selected land, and 35-45kg of compound fertilizer is applied per mu; (2), each seed sample is sown in the same small area, observation areas are arranged around the small area, each group of seed samples are sown in the same identification planting area, and protection rows are arranged around the identification planting area; (3), sowing is carried out in the small areas and the protection rows according to the standard that the row spacing is 23-27 cm and the plant spacing is 8-12 cm; and (4), the purity of the wheat seeds is identified. According to the field plot planting identification method for the winter wheat seed purity, sowing grain number and sowing mode are reasonable, manpower and material resources can be saved, the purity of the wheat seeds can be accurately identified, the elimination value or the purity percentage value of different varieties can be reasonably applied, and the accepted or eliminated seed batch can be accurately judged. The identification result is accurate, and reliable guidance is provided for wheat planting.

Description

technical field [0001] The invention relates to the technical field of germplasm identification, in particular to a field planting identification method for the purity of winter wheat seeds. Background technique [0002] Winter wheat is the main ration in northern my country. The quality of wheat seeds is related to the safety of wheat production. Seed purity and authenticity are the most important indicators of seeds, which are crucial to wheat production. Planting identification in field plots is one of the most accurate and reliable methods for testing wheat seed quality, but there is no scientific method for planting identification of wheat seed quality. Various seed inspection agencies conduct planting identification according to their own design methods, and the specific methods are different. . Especially in the period of rejuvenation, jointing and booting stage of seedlings and wax ripening stage, the traits and standards identified are missing, and the two methods ...
