Paris polyphylla var yunnanensis and paris polyphylla var chinensis seedling three-phase breeding technology

Abstract

The invention discloses a Paris polyphylla var yunnanensis and paris polyphylla var chinensis seedling three-phase breeding technology comprising the following steps: 1, seed selection; 2, seed pretreatment: selecting cleaned rude river sand to rub the seeds until a seed outer red aril falls off, the rubbing process cannot be too long to cause the inner layer seed surface to damage, and carrying out low temperature treatment, changing temperature treatment, normal temperature treatment and constant temperature water immersion treatment for the seeds removing arils, and reserving the seeds for usage; 3, embedding and accelerating germination: uniformly sowing the immersed Rhizoma Paridis seeds, watering the seeds for moisture, and carrying out embedding accelerating germination treatment for a watered sowing basket; 4, transplanting the emerged seedling. The novel technology can effectively reduce Rhizoma Paridis seed seeding formation time; after seed pretreatment, embedding accelerating germination and transplanting seedling, the emergence rate of the Paris polyphylla var yunnanensis and paris polyphylla var chinensis can respectively reach 70% and 80%, thus greatly reducing time cost for production and resource large scale utilization, and improving efficiency.

Description

technical field [0001] The invention relates to the field of biotechnology, in particular to a three-stage propagation technique of Dianchonglou and Huachonglou seedlings. Background technique [0002] Papyrus is a general term for plants of the genus Paris in the family Trilliaceae. There are 24 species of Pachyphylla plants in the world, mainly distributed in the tropical and cold temperate regions of the European continent abroad, and 19 species in my country, mainly distributed in Yunnan, Guizhou, Sichuan and other places. As a precious medicinal plant, the steroidal compounds contained in its rhizomes have hemostatic, anti-inflammatory, and analgesic effects. It is one of the main raw materials of famous Chinese patent medicines such as "Yunnan Baiyao" and "Gongxuening". Yunnan Province is rich in climate resources, including various climate types such as tropical, subtropical, temperate, and frigid; the terrain is complex, including valleys, basins, hills, mountains, ...

AI Technical Summary

Problems solved by technology

The germination and dormancy period of the seeds of the plant of the genus Chonglou is long, it is difficult to break the dormancy, and the germination rate is low. The conventional planting method usually takes about seven years from sowing to the harvest of medicinal materials, and other invention patents for seed germination also often need more than 4 months, which is extremely large. To a certain extent, the development and utilization of heavy building resources are limited, and wild digging has become the main channel to obtain this resource.
