Cutting propagation method for Chinese yew by seedling pots

Abstract

The invention relates to a cutting propagation method for Chinese yew by seedling pots. The method includes the steps of preparation of nutrient substrate, preparation of seedling pots, selection of shoots, pre-cuttage treatment, cuttage in fields, post-cuttage sterilization, temperature and humidity holding, subsequent management and the like. The cutting propagation method for Chinese yew by seedling pots facilitates post-cuttage transplanting or pot replacement for Chinese yew, is convenient and enables survival rate of Chinese yew to be higher.

Description

technical field [0001] The invention relates to a yew nutrition pot cutting seedling raising method. Background technique [0002] Taxus, also known as yew, has eleven varieties in the world. In my country, there are five varieties of yew in Yunnan, yew in Tibet, yew in Northeast China, yew in China and yew in the south, among which the yew in the south is a variant. [0003] Wild yew reproduces naturally, relying on birds to peck the yew fruit, the yew seeds are excreted through feces, and it takes two years of dormancy to germinate after landing. During this period, it is easy to be eaten by small animals such as mice and squirrels on the mountain Yes, if the yew seeds are not pecked by the birds, they cannot germinate, so the wild yew reproduces slowly, and the emergence rate is not high. Therefore, the country has listed the yew as a national first-class protected plant. [0004] In the 1990s, the artificial seed-seeding and breeding of the southern yew was successful, ...

AI Technical Summary

Problems solved by technology

[0005] One is that yew seeds must go through a dormancy and wake-up period, which is longer;

[0006] The second is that the yew must be manually ground the protective layer outside the seeds, otherwise it is not easy to germinate, which is time-consuming and increases the cost;

[0008] Fourth, seed sowing or other methods of propagating yew are not convenient for transplanting

Because the yew grows to a certain height, it must be transplanted or repotted, and the seedlings of the yew that are seeded or other cuttings must be transplanted or repotted from the soil. If the method is not appropriate, the root system of the yew will be damaged and the survival will be affected. Rate;

[0009] Fifth, the survival rate of yew by seed sowing is not high, so it cannot be popularized quickly
