Paris polyphylla low elevation and high altitude seedling cultivation method

Abstract

The invention discloses a Paris polyphylla low elevation and high altitude seedling cultivation method. The method comprises the steps of the selection of low elevation seedling soil, the seedling sowing and rearing, the selection of high altitude cultivated soil, the seedling transplanting and the management of water and fertilizer. The seedling cultivation method takes full advantage of the differences in natural environmental conditions under different altitudes, does not require a dedicated variable temperature device, in comparison with other methods, the seedling out-planting time is at least shortened by 180 days, the germination rate is improved, and the seedling root weight is increased by 2-2.5 times, the annual growth of the rhizome of Paris polyphylla is increased, the growth cycle of Paris polyphylla is significantly shortened, the growth cycle is shortened by 40%, the production cost is low, and the method is easy to master and extend.

Description

technical field [0001] The invention relates to a low-altitude seedling raising and high-altitude planting technology of Chonglou dianthus. Background technique [0002] Pairs polyphylla var.yunnanensis belongs to Trilliaceae (Trilliaceae) Pairs polyphylla (Paris L.) perennial herb, which is recorded in "Pharmacopoeia of the People's Republic of China". The main chemical composition of its rhizome is steroidal saponins. With strong physiological and pharmacological activities, it is the main component of some important Chinese patent medicines and new medicines such as Yunnan Baiyao, Sichuan Baiyao, Gongxuening, Duoming Dan, and Total Saponin Tablets. Due to the high medicinal value of Dianzhonglou, the demand has increased year by year in recent years. According to statistics, the current demand for Dianzhonglou in pharmaceutical factories and traditional Chinese medicine prescriptions across the country can reach about 16,000 tons. Relying on wild resources alone can no l...

Problems solved by technology

[0004] The purpose of the present invention is to utilize the differences in temperature and humidity under different altitude conditions to provide a method for cultivating and planting of Prunus diangi with strong operability and low production cost, so as to solve the problem of late emergence, low emergence rate and long growth cycle of Prunus diangi The problem

The present invention aims at the problems of complicated temperature-changing germination process and slow growth of rhizomes in the seedling stage in the prior art, uses low altitude, high temperature and air humidity to raise seedlings, shortens the emergence time of Dianzhonglou, increases the weight of rhizomes in seedling stage, and then Transplanted to high-altitude areas for planting, increasing the annual growth of the rhizomes of Prunus edulis and shortening the planting cycle of P.
