Taxus chinensis vegetative propagation rapidly rooting method

Abstract

The invention relates to the technical field of plant vegetative propagation, in particular to a taxus chinensis vegetative propagation rapidly rooting method. The method comprises the steps of building a seedbed, collecting taxus chinensis detached materials, manufacturing and processing; selecting a number one ABT rooting powder as rooting agent, manufacturing solid rooting liquid by using water-retaining agent, inserting the taxus chinensis into the seedbed, distributing the solid rooting liquid on the seedbed and managing the seedbed during growing seeding. By using a function of absorbing a hundred times of water of the water-retaining agent, the used rooting liquid is diluted into the rooting liquid with a low density, and is absorbed again to form the solid rooting liquid; and the solid rooting liquid provides the detached materials with medicine liquid in a slow and uniform mode in a whole, middle and later period in a substrate,, carries out omnibearing induced root treatment so as to promote the detached materials to grow root in a short period. The water-retaining agent absorbs and stores rich water on leaf surfaces according to the function of the water-retaining agent, and provides the rich water to the detached materials in a slow and uniform mode. The detached materials can grow in a healthy and strong way and grow up to seeding as quickly as possible.

Description

technical field [0001] The invention relates to the technical field of plant vegetative propagation, in particular to a method for rapid rooting of yew vegetative propagation. technical background [0002] Yew, an evergreen tree, is an ancient and rare tree species left over from Quaternary glaciers. It has a history of 2.5 million years on the earth. Due to the slow growth rate and poor regeneration ability of yew under natural conditions, there has not been a large-scale yew raw material forest base in the world for a long time. Therefore, yew is recognized as an endangered natural and rare anti-cancer plant in the world. China has listed it as a first-class rare and endangered plant, and the United Nations has also banned its logging. [0003] Taxus is a rare and endangered plant, and it is also an important medicinal plant. Paclitaxel extracted from yew is an internationally recognized anti-cancer and anti-cancer drug. High-purity paclitaxel is expensive, as high as 2 ...
