Embodiment Construction

[0006] The present invention will be described in further detail below in conjunction with the examples, but it does not constitute any limitation to the present invention.

[0007] First, carry out seed germination. The seeds are harvested when the fruit is dark red. The seeds are post-physiologically mature and need to be stored in wet sand for one year before they can germinate. The outdoor natural wet sand storage and stratification method is adopted to process the seeds to increase the germination rate. Second, select the nursery for sowing. It is better to grow seedlings and transplant under pine forests according to local conditions. Choose slash pine or masson pine with a canopy density of 0.6-0.7 and no pests and diseases as nursery land. It requires gentle slope, deep upper layer and good drainage. Remove weeds and shrubs in the forest from August to September, organize them into horizontal terraces, dig 20-30 cm deep, and rake them shallowly in November. When pre...

Abstract

The invention discloses a high-survival-rate seed seedling method for taxus chinensis trees. The high-survival-rate seed seedling method comprises seed collection germination acceleration and nursery garden selection seeding and is characterized in that in the seed collection germination acceleration process, seeds are collected when fruits are in dark red, and the seeds are stored for one year by an outdoor natural wet sand layer composition method; and in the nursery garden selection seeding process, the seeds are sieved when 30 percent of seeds stored for one year have the crack phenomenon, the seeds are placed into 0.2 percent potassium permanganate solution to be sterilized for ten minutes, then, the seeds are cleaned through being flushed by clean water and are dried, and the seeding is carried out in early spring. The seed collection germination acceleration and nursery garden selection seeding methods are adopted in the invention, the optimum seed breeding natural conditions of the taxus chinensis under the natural condition are possibly met, the sprout growth is promoted, and the survival rate is improved.

Description

technical field [0001] The invention relates to a method for raising seedlings, in particular to a method for raising seedlings of yew trees. Background technique [0002] Taxus is an endangered tree species in the world, with high ornamental and medicinal value, especially the paclitaxel extracted from it has won worldwide recognition for its unique anti-cancer mechanism and remarkable curative effect, and has gradually become an anti-cancer First-line drugs with huge market potential. But at present, the professional planting of yew trees is still in its infancy, and it faces many problems such as seedling cultivation and unsuitable climate. The survival rate of the traditional method for raising seedlings by seeds is relatively low, and there is no report on a mature method for raising seedlings of Taxus chinensis at present. Contents of the invention [0003] The purpose of the invention is to provide a method for raising yew seeds with higher survival rate. [0004...
