Problems solved by technology

However, the long-term asexual reproduction leads to the mixed breeding and aging of Polygonatum plants, resulting in planting degradation, poor resistance, and serious plant virusization, which leads to the phenomenon of yield reduction.
The current seed propagation is mainly to select mature and plump seeds for sand storage immediately after the seeds mature in August, and to sift out the seeds for seedling cultivation in the second year. This kind of seed breeding method, in the process of sand storage, although it will be in advance. End the dormancy of Polygonatum seeds, but in the process of sand storage, a large amount of nutrient

Example Embodiment

[0018] Example 1:

[0019] A method for breeding Polygonatum, including the following steps:

[0020] 1) Put the Polygonatum seeds in a bucket filled with water for soaking fermentation. The fermentation time is 25 days and the water temperature is 25℃. The Polygonatum seeds used are the newly picked Polygonatum seeds that are naturally mature and dried. The start time is the 10th of October in the Gregorian calendar;

[0021] 2) Wash the Polygonatum seeds after fermentation with clean water. The cleaning process is manual elutriation. After washing, the water must be drained before refrigeration. Lay the cleaned Polygonatum seeds on the culture medium. The culture medium is fermented. Rice bran, and then the culture medium is refrigerated in a refrigerating room in an aerobic environment. The refrigerating time is 25 days, the temperature of the refrigerating room is 2℃, the air moisture content of the refrigerating room is 11%, and the oxygen concentration of the refrigerating roo...

Abstract

Provided is a method for breeding seeds of polygonatum cyrtonema Hua. The method comprises the following steps of: (1) putting the seeds of polygonatum cyrtonema Hua in a water-containing bucket for immersion and fermentation, wherein the fermentation time is 25-35 days, and the water temperature is 25-29 DEG C; (2) cleaning the fermented seeds of polygonatum cyrtonema Hua with clear water, layingthe cleaned seeds of polygonatum cyrtonema Hua on a culture medium, and then performing cold storage on the culture medium in an aerobic-environment refrigerating room, wherein the time of cold storage is 25-35 days, the temperature of the refrigerating room is 2-6 DEG C, the moisture content of the air in the refrigerating room is 11-18%, and the refrigerating room is internally provided with acold-light lamp; and (3) sowing the refrigerated seeds obtained in the cold environment to loose soil for seedling cultivation. According to the method for breeding the seeds of polygonatum cyrtonemaHua, not only can a high germination rate of the seeds of polygonatum cyrtonema Hua be ensured, but also the hibernation period of the seeds of polygonatum cyrtonema Hua is shortened, so that the seedbreeding process is shortened, the breeding process is simple, and the method for breeding the seeds of polygonatum cyrtonema Hua is easy to popularize and apply.

Description

technical field [0001] The invention relates to a breeding method, in particular to a breeding method of Polygonatum. Background technique [0002] Polygonatum is a perennial herb of the genus Polygonatum in the family Liliaceae. It is an important traditional Chinese medicinal material with a long history of medicine. Polygonatum contains polysaccharides, steroidal saponins, lignans and other chemical components, which have a wide range of pharmacological effects such as cardiovascular protection, hypoglycemic and lipid-lowering, neuroprotective, immune regulation, anti-tumor, antibacterial and antiviral. Our country is rich in sealwort resources, because of its medicinal, edible, ornamental and cosmetic value, the market demand is increasing day by day, it has good economic benefits, and the market prospect is very broad, thus promoting the development of sealwort planting technology. [0003] At present, in the planting process of sealwort, its propagation method mainly ...
