Problems solved by technology

[0003] In recent years, on the one hand, due to the massive excavation of its underground parts to extract podophyllotoxin, the amount of wild resources has decreased sharply and the ecological environment has been destroyed. On the other hand, the use of its fruits in Tibetan medicine also directly affects the natural renewal of its resources. At present, there is no large-scale cultivation and production. The population of Taoerqi is decreasing sharply, the asexual and sexual reproduction ability is greatly weakened, and the resource is facing endangered situation. Included in the Red Book of Plants, it is a third-level protected plant

Embodiment 1

[0023] A kind of method for raising seedlings of Taoerqi is completed according to the following steps:

[0024] (1) Seed harvesting: generally from mid-August to the end of September, when the fruit of Taoerqi is fully ripe and red, it is harvested. After the fruit is harvested, the skin is peeled, and the pulp on the seeds is washed with clean water to remove the unfulfilled the seeds, dry the moisture on the surface of the seeds for subsequent use;

[0025] (2) Seed treatment: Soak Taoerqi seeds of the moisture on the surface of the seeds with 0.5% potassium permanganate solution for 2 hours, clean them with clear water, mix the seeds and river sand in a ratio of 1:3, and The water content of the sand is about 30%. Put the mixed mixture into a mesh bag. The mesh size of the mesh bag should be filled with river sand without leakage. Choose a well-permeable plot to dig a hole and bury the mesh bag in the soil. Fill the mesh bag with soil, and cover it with a layer of 20 cm t...

Abstract

The invention relates to the technical field of plant planting, in particular to a method for cultivating seedlings of podophyllum hexandrum. The technical scheme comprises seed collection and harvest, seed treatment, seedling cultivating field selection, field preparation, sowing, field management and transplanting. According to the method for cultivating the seedlings of podophyllum hexandrum, seeds of podophyllum hexandrum are stored in low temperature sand so as to break the dormancy of the seeds of podophyllum hexandrum, and the germination rate of the seeds is improved. The germination rate of the seeds of podophyllum hexandrum treated by the method for cultivating the seedlings of podophyllum hexandrum is up to 95% or above, and the survival rate of the seedlings of podophyllum hexandrum reaches 90% or above.

Description

technical field [0001] The invention relates to the technical field of plant planting, in particular to a method for raising seedlings of Pteris chinensis. Background technique [0002] Sinopodophyllum hexandrum is a perennial herb of the genus Sinopodophyllum hexandrum in the family Berberidaceae, distributed in Yunnan, Sichuan, Shaanxi, Gansu, Tibet, Hubei in my country, India, Nepal and other places abroad. There are also distributions. Its roots, rhizomes, leaves and fruits are all folk herbal medicines, and are medicinal plants with a long history of application. Recent studies have shown that the roots and rhizomes of Taoerqi have a high content of podophyllotoxin (Podophyllotoxin), which is a synthetic VP16 (Etoposide) and VM26 (Teniposide) and other anti-cancer drug precursors, but also the drug of choice for the treatment of skin cancer and venereal warts. At present, the medicinal use of Taoerqi is that the underground part (podophyllum) is used to extract podophy...
