Example Embodiment

[0025] Example 1

[0026] A three-stage propagation technique for seedlings of Dianzhonglou and Huazhonglou, including the following steps:

[0027] (1) Selection:

[0028] Choose healthy seeds from the plant that were harvested that year, free of disease and mildew;

[0029] (2) Seed pretreatment:

[0030] Use washed coarse river sand to dress the seeds, and knead until the outer red aril of the seed peels off. During the kneading process, avoid damage to the inner seed surface due to too long time; then, the seeds after removing the aril are subjected to low temperature Treatment, variable temperature treatment, room temperature treatment, constant temperature water immersion treatment, ready to use;

[0031] (3) Embedding and accelerating germination:

[0032] Choose a plastic basket containing the seeding substrate, mix the soaked seeds of the edible seedlings with the substrate, and evenly sow and water them for moisturizing; embed the watered seeding basket for sprouting treatment,...

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, ...
