A method for high-efficiency raising seedlings of wild Parisia dianthus seeds

Abstract

The invention discloses a high-efficiency seedling breeding method for wild paris polyphylla seeds. Capsules are soaked by means of an ethephon solution, so that the after-ripening of the paris polyphylla seeds in morphology and physiology is completed with acceleration. Seed dormancy is broken and cuticles are removed through burying capsule clusters and washing with plant ash water, so that the paris polyphylla seeds enter the rooting stage from the dormant state. Finally, the duration from picking to one leaf growing of each seed is controlled in 6 to 7 months, the germination rate reaches 90% or above, the emergence rate reaches 85% or above, and the survival rate of transplanting reaches 97% or above. Meanwhile, after transplantation in fields, the plant height can reach 50 cm and the weight of a tuberous root can reach 50 grams or above in the next year, some of plants can come into two rounds of leaves and start to bud and bloom, which far surpass the natural growth rate. The invention belongs to the field of medical material seedling breeding.

Description

technical field [0001] The invention relates to a seed breeding method of wild Chonglou dianthus, and belongs to the field of seedling breeding of medicinal materials. Background technique [0002] Dianzhonglou is a perennial herbaceous plant of Liliaceae, and its main production areas are Guizhou, Yunnan, Sichuan and other provinces. There are wild seed resources in Zunyi and Xingren in Guizhou. Both the roots and stems of Dianzhonglou can be used as medicine, which has the functions of clearing away heat and detoxification, reducing swelling and pain, cooling the liver, calming convulsions, etc. It can be used to treat symptoms such as pain and swelling, poisonous snake bites, bruises, sprains, convulsions and convulsions. It is the main ingredient of Yunnan Baiyao series products. Due to human over-excavation and environmental damage in recent years, wild resources are on the verge of depletion. Artificial introduction and domestication planting is the only way to prote...

AI Technical Summary

Problems solved by technology

Artificial introduction and domestication planting is the only way to protect wild germplasm resources. At present, the seed breeding technology of Chonglou dianthus is mainly the treatment method of growing roots in four months and growing leaves in eight months, and the germination rate and seedling rate are more than 85% (see Patent 201410502503.9), slow growth, low germination rate and seedling rate
