A rapid seedling raising method for promoting the high germination rate of Panax notoginseng by using Acremonium acremonium

Abstract

The invention discloses a rapid seedling-raising method capable of promoting high germination rate of pseudo-ginseng by utilizing acremonium strictum. The rapid seedling-raising method comprises the following steps: acremonium strictum strain culturing, seed treatment, sowing, breeding management, and germination and transplanting. According to the invention, compared with traditional irrigation of seeds with water, the germination rate of pseudo-ginseng seeds is increased by 20% or more, and can reach up to 90% or more; the time of seedling raising can be shortened by 10 to 20 days; meanwhile, the cultured seedlings are strong and neat and grow rapidly, and the time of seedling raising can be saved, so great significance on plantation of the pseudo-ginseng is obtained.

Description

technical field [0001] The invention relates to the field of seedling raising methods, in particular to a rapid seedling raising method using acremonium acremonium to promote a high germination rate of Panax notoginseng. Background technique [0002] Panax notoginseng is a perennial herb of Araliaceae ginseng. It is known as "gold does not change" and "sacred grass in the south". Its roots, stems and flowers can be used as medicine. It is a rare and precious Chinese medicinal material unique to Yunnan. Current pharmacological studies have shown that Panax notoginseng has pharmacological activities and unique curative effects in the blood system, cardiovascular system, nervous system, immune system, metabolic system, and anti-inflammatory, anti-aging, and anti-tumor methods. The planting methods of Panax notoginseng are usually seed collection, preservation, seedling raising, transplanting and harvesting. The means of raising seedlings adopted at present is to sow the seeds ...

AI Technical Summary

Problems solved by technology

In the prior art, Panax notoginseng seedlings are generally buried in soil or matrix seedlings after being directly buried in wet substrate seedlings and sterilized and dried in refrigerators. Although compared with natural environment, the germination rate of Panax notoginseng seeds can be improved. However, the germination rate can only reach 50-70%, and the germination time is as long as 45-60 days, which seriously restricts the development of Panax notoginseng planting industry

Moreover, affected by various extreme climate conditions in recent years, the germination rate of Panax notoginseng seeds and the survival rate of seedlings have been greatly reduced under the existing technical conditions. Therefore, it is of great significance to study how to quickly improve the germination of Panax notoginseng seeds.
