Leymus chinensis culture method and application thereof in seed production

Abstract

The invention discloses a leymus chinensis culture method and application thereof in seed production. The leymus chinensis culture method comprises the following steps: (1) sowing leymus chinensis seeds in spring; (2) immediately conducting water irrigating once after sowing, conducting water irrigating for multiple times from emergence of leymus chinensis seedlings to the end of the trefoil stage to replenish water, and determining whether irrigation needs to be conducted according to actual situations from the end of the trefoil stage to the time before overwintering; and (3) performing the following operations every year from the second year of sowing: applying a fertilizer once every 10-20 days after leymus chinensis turns green, immediately conducting water irrigating once after fertilizer application, and determining whether irrigation needs to be conducted according to actual situations from the time that the leymus chinensis turns green to the time before overwintering. A Zhongke leymus chinensis field management method provided by the invention is simple and feasible and can greatly improve the yield of leymus chinensis seeds when popularized in a large area in an artificial leymus chinensis land, so that the pressure of demands on high-quality leymus chinensis seeds in China is relieved, and ecological benefits are realized to a great extent while economical benefits are realized.

Description

technical field

[0001] The invention relates to a method for cultivating Leymus chinensis and its application in producing seeds. Background technique

[0002] Leymus chinensis is a perennial high-quality forage grass in the family of Poaceae in northern my country. It has wide adaptability and has the advantages of salt-alkali tolerance, cold tolerance, and drought tolerance. It is widely distributed in the eastern Eurasian steppe region and is one of the most valuable grasses in my country. High-quality Leymus chinensis is not only a favorite food for cattle and sheep, but also can be used for restoration of degraded and desertified grasslands and improvement of salinized land. The new species of Leymus chinensis has been propagated and demonstrated on a large scale in northern my country, but the shortage of seeds has gradually become the main bottleneck of popularization and planting. Using science and technology to increase the yield of Leymus chinensis seeds is a key ...
