Method for increasing germination rate of sophora davidii seeds

Abstract

The invention belongs to the technical field of plant cultivation, and discloses a method for increasing a germination rate of sophora davidii seeds, which comprises the following steps: placing the sophora davidii seeds in a stirring barrel, pouring enough water into the stirring barrel, and stirring; fishing out the seeds precipitated at the bottom of the stirring barrel through a filter screen,and filtering out water; spreading the seeds on absorbent paper, and airing and drying the seeds; soaking the dried seeds in warm water, then soaking the seeds in a salt water solution, taking out the seeds, and washing the seeds with water; selecting a dry area without accumulated water, deeply digging a soil pit, digging drainage ditches around the pit, mixing humus soil with the sophora davidii seeds, putting the mixed seeds into the pit, covering the seeds with soil, and performing sand storage; keeping the soil moist, and sowing the seeds after the seeds crack after 10-15 days. Accordingto the method, the seeds are treated before sowing, growth hormone is not used in a whole process, seed vitality can be promoted, and the germination rate can be improved.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation, and in particular relates to a method for increasing the germination rate of Nitraria japonica seeds. Background technique [0002] White thorn flower is a perennial evergreen shrub of the genus Sophora genus Fabaceae, distributed in North China, Shaanxi, Gansu, Henan, Jiangsu, Zhejiang, Hubei, Hunan, Guangxi, Sichuan, Guizhou, Yunnan, Tibet and other places. It germinates twice a year, has good palatability, and is rich in nutrition. It can be used for grazing all year round. In addition to direct grazing or cutting green fodder, it can also be processed and used as silage alone or mixed with other pastures. High-quality and safe medicine-feeding dual-purpose high-protein forage grass; at the same time, the flowers are rich in honey, and it is a high-quality nectar source plant and a pioneer plant for landscaping and ecology. The flowers and seeds have the effects of clearing heat, de...

AI Technical Summary

Problems solved by technology

[0005] (1) The existing Nitraria japonica seeds have the problem of low germination rate, and the germination rate is about 15% under natural conditions

[0006] (2) Nitraria japonica seeds whose germination rate has been improved after being soaked in growth hormone develop slowly or wither quickly in the later stage, which does not meet the needs of grassland establishment, landscaping and ecological construction
