Rapid propagation technique of Paris polyphylla var. yunnanensis, seedling exercising and planting methods

Abstract

The invention relates to a method of Paris genus rapid propagation technique and seedling exercising, planting, comprising filtering a high grade individual system, sterilizing and tissue culture, wherein seedling exercising is the key to increase success ratio of the plant. The invention first performs Paris genus seedling exercising using microelement, causing the seedling exercising success ratio to reach 80%, thereby ensuring planting success ratio to reach 80%. The seedling exercising comprises: putting regeneration young seedlings in a culture medium added with vitamine and phytohormone, then adding microelement for cultivation and transplantation. The planting method comprises: transplanting the young seedlings through seedling exercising in sterilized prescription coil culture bag, when the newly put forth terminal bud develops into the blade, namely transplanted to the outside for insect control. The inventive technology and method ensure coherence of the germchit quality, ensuring high quality seed source of the Paris genus. The success ratio of the seedling exercising reaches 80%. The main root is thick and fibrous roots are increase, adaptability is strong in the field, the success ratio of the field reaches more than 80%, which solves problems of uneasy radication, immature seedling exercising technique, uneasy survival of planting. The invention is characterized by short vegetative cycle, low in production cost, good in quality and has scale production.

Description

technical field [0001] The present invention relates to a rapid propagation technique of Prunus diangi and methods for seedling hardening and planting. Background technique [0002] Chonglou is a species included in the "Chinese Pharmacopoeia". It is an important and scarce Chinese herbal medicine in the compatibility of Yunnan Baiyao and traditional Chinese medicine. , the resources are becoming increasingly exhausted. Although there are plantations in China, they germinate 1-2 years after sowing, and the provenance has not yet been resolved. With the rapid growth of the demand for raw materials of chrysanthemum by Chinese pharmaceutical companies, chrysanthemum has gradually become a rare species that is on the verge of extinction. endangered species. [0003] At present, there is no research report on this related technology in foreign countries. The research on the introduction and domestication of Chonglou and artificial cultivation technology in my country has begun s...

AI Technical Summary

Problems solved by technology

The production of seedlings by tissue culture can shorten the emergence cycle and make the species single, but the bottleneck problem that the tissue culture seedlings are not easy to take root, and the planting is not easy to survive has not been solved. There is no breakthrough in the survival rate of the tissue culture seedlings of D. , but there are no successful and good results reported in the literature

[0012] 5. There are problems in the tissue culture seedlings of Parisia dianthus

[0013] The tissue-cultured seedlings of P. dianthus are not easy to take root, the seedling hardening technology is immature, and the planting is not easy to survive. This is the bottleneck problem that has plagued scientific and technological workers for many years and has not been solved.
