Culturing method for sorrel

Abstract

The invention discloses a culturing method for sorrel and belongs to the technical field of high mountain medicinal plants. The method comprises steps of selecting a land, processing seeds, nursing seedlings, managing seedling nursing and transplanting. A seedling nursing land and a fixed-plantation field are selected; and seedlings are nursed in seedling nursing discs and transplanted in the near places. The culturing method for sorrel is advantaged by small seed use amount, high seed vigor, high planting percent, fast growth speed and uniformed seedlings; plenty of excellent seeds can be achieved in short period; and strong seedling adaptability and high transplantation survival rate can be achieved.

Description

technical field [0001] The invention belongs to the technical field of cultivation of alpine medicinal plants, and in particular relates to a cultivation method of rhubarb palmatum. Background technique [0002] Rhubarb palmatum is a plant of the genus Rhubarb in the family Polygonaceae. It is a commonly used bulk medicinal material, and its dried roots and rhizomes are used as medicine. Rhubarb palmatum is one of the world-renowned specialties and important medicinal materials in my country. It has a medicinal history of more than 2,000 years at home and abroad. Rhubarb is still a good medicine for venting excess heat, defecation, stagnant stagnation, and blood stasis. It is an important raw material of dozens of Chinese patent medicines such as Qingwan and Huanglian Qingwei Pills. At present, low-alcohol rhubarb wine, rhubarb drinks, and rhubarb diet pills are very popular in the market. For a long time, in addition to domestic use, rhubarb has been an important export ...

AI Technical Summary

Problems solved by technology

For a long time, medicinal rhubarb has been a kind of wild plant. Although some people have planted it sporadically in recent years, they are all extensive. First, the output is low; second, the quality of finished products is uneven; Artificial planting is less effective

[0003] At present, rhubarb is planted by direct seeding and transplanting seedlings. The amount of direct seeding seeds is large, the emergence of seedlings is poor, the growth is slow in the first year, and management is difficult such as intertillage and weeding. Raising seedlings in the original place can only be sown in the middle and late April after thawing. Due to the high altitude and temperature difference Large changes, low seed germination rate, large amount of seeds used, inconvenient field management, affecting the quality of rhubarb seedlings, and transplanting in April of the second year, affecting the promotion of wild varieties of rhubarb and other alpine medicinal materials

Invention patent CN103385087B improves the method. Taking advantage of the high temperature in autumn and winter in low-altitude areas, it is suitable for the growth and safe wintering of rhubarb seedlings. The low-altitude seedlings are raised in autumn and winter. The seedlings will be transported to high mountains for planting in the next year, which will accelerate the growth process of rhubarb. The harvest that can only be harvested after planting for four years can be harvested in the third year. This method needs to be transported, transplanted and planted rhubarb in different places. There is a possibility that the newly introduced rhubarb seedlings in different places will wither if they are not suitable for the local soil, and they will not adapt to the local water, soil and climate conditions. Will die and other problems, and this method does not treat the seeds to increase the germination rate, germination potential to shorten the germination time and enhance seed vigor
