Cutting nursery test method for Taxus media

Abstract

The invention discloses a cutting nursery test method for Taxus media. The method comprises the following steps: selecting branches of proper cutting seedlings for carrying out cuttage test by taking the branches as cuttings; partitioning a test group into a slow soaking group and a quick soaking group for soaking; researching the actions of growth regulating substances on the rooting of the cuttings and the growth of seedlings respectively to obtain a most proper growth regulating substance; researching different concentrations of the growth regulating substances on the rooting of the cuttings and the growth of seedlings respectively to obtain a most proper concentration; researching the treatment time of the growth regulating substances on the rooting of the cuttings and the growth of seedlings respectively to obtain most proper treatment time; comparing the influences of two soaking treatment methods on the rooting of the cuttings and the growth of seedlings, and selecting a most proper treatment method; researching the relations between the types of the cuttings and the rooting of the cuttings to obtain a most proper cutting type. By adopting a scientific culture technology for cutting nursery for the Taxus media, the breeding and development of the Taxus media are facilitated.

Description

technical field [0001] The invention belongs to the field of plants, and in particular relates to a cutting seedling raising technique of Taxus chinensis and research on its resistance physiology. Background technique [0002] Mandia yew is one of the yews. The yew is a relict plant of the Quaternary Glacial Age. It is a rare and endangered species in the world. There are eleven species in the world. At present, there are four species and one variety in my country, namely Yunnan red bean Chinese yew, Tibetan yew, Northeast yew, Chinese yew and southern yew. Distributed in my country's southwest, northeast, central, southern and other regions. Mandia yew was introduced from Canada in the mid-1990s in my country. It is now cultivated in Sichuan, Guangxi, Shandong and other places. [0003] At present, the research on cutting seedling raising technology and resistance physiology of Taxus Mandia in our country is not in-depth, and there is a lack of specific instructions for t...
