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
