AI Technical Summary
The sheep grass in the Northeast region has undergone varying degrees of degradation due to excessive grazing, mowing grass, and large-scale land reclamation, resulting in a low rate of sheep grass, which limits the development of animal husbandry and damages the ecological environment.
A plant growth regulator is provided, including 2,4-dichlorophenoxyacetic acid, indole-3-acetic acid, gibberellin and 6-benzyl aminopurine, to increase the fruiting rate of olfactory grass by spraying. Specific methods include preparing four different concentrations of plant growth regulator combinations and spraying for the first and re-spray during the flowering period of the wool.
By using the plant growth regulator and spraying method, the fruiting rate of sheep grass can be improved and its growth performance can be enhanced, thereby improving the grassland ecological environment and animal husbandry development.

[0002] Leymus chinensis, also known as alkali grass, is a typical perennial rhizome grass. In Northeast my country, whether it is natural grassland or artificial grassland, Leymus chinensis plays an important role as a community species. It not only has excellent characteristics such as strong salt-alkali resistance and drought resistance, but is also a high-quality feed with high nutritional value and good palatability, and has important ecological and economic value. In recent years, due to excessive grazing, mowing, and large-scale land reclamation by humans, more than 70% of the Leymus chinensis grasslands in Northeast China have undergone varying degrees of degradation, which not only restricts the development of animal husbandry, but also damages the ecological environment and endangers human survival.
[0003] Currently, there are few methods for improving the fruit set rate of Leymus chinensis.
[0004] Therefore, it is necessary to provide a new plant growth regulator for improving the fruit setting rate of Leymus chinensis and a spraying method thereof to solve the above technical problems. Summary of the invention
