Embodiment Construction

[0033] A kind of cutting propagation method of Chinese yew, the method is as follows:

[0034] (1) Selection of branches for cuttings

[0035] When choosing branches for cuttings, you must choose 1-year-old branches, which are easy to take root and have a high survival rate. On the contrary, without rooting, the survival rate is low. The length of the branches is not limited, generally more than 10cm.

[0036] (2) Branch preservation and transportation methods for cuttings

[0037] 1) The cut branches must be hidden in a cool place, and the humidity of the branches and leaves must be kept, and they must not be exposed to the sun or air-dried;

[0038] 2) Soak the branches in clean water before packaging, pick them up immediately, and shake the water droplets on the branches lightly; the purpose is to ensure the humidity and freshness of the branches during transportation.

[0039] 3) The branches are packaged in plastic bags, usually plastic bags that can hold 10-15 kg, an...

Abstract

The invention relates to a cuttage breeding method of taxus chinensis in northeast, comprising the following steps: selecting a one-year-old branch as a branch for cuttage; concealing the branch at ashade place, and carrying the branch to a destination after the branch is packaged by a plastic bag; retaining 1-2 leaves on the upper end of each nursery stock stalk when shearing a seedling, shearing the parts longer than 3cm of the retained leaves, and also shearing leaves inserted into the stalk positioned in the middle of a seedling bed; disinfecting a land before the cuttage so as to reducerhizoctonia solani kuhn, and carrying out the cuttage from the middle ten days of October to the first ten days of November or from February to March; using a light shielding net of 80 percent to shield light without directly shining with the sun during the daily management of the seedling; controlling the soil water content at 35-45 percent; and paying attention to the water drainage of the seedling in rainy days and intertillage weed control in ordinary days, and preventing and curing diseases of the seedling in time by chemical agents. By adopting the cuttage breeding method, the taxus chinensis in northeast has high survival rate, fast breeding cultivation and high disease resistance.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation, and in particular relates to an artificial cutting propagation method of Chinese yew. Background technique [0002] Taxus chinensis, also known as Taxus chinensis, can extract paclitaxel from Taxus chinensis plants. Taxol has a unique mechanism and significant anticancer activity, which has attracted the attention of scholars at home and abroad. Chinese scholars have extracted 9 compounds including taxol from Taxus chinensis, which shows that Taxus chinensis has good development prospects. [0003] At present, judging from the distribution area of ​​Northeast yew, its pure forests are rare, mostly scattered dry Korean pine and broad-leaved mixed forests, and the distribution range is getting smaller and smaller, and it is currently on the verge of extinction. The main reasons for the endangerment of yew resources in Northeast China are as follows: First, human-induced destructive facto...
