Description
Technical Field
The invention belongs to the technical field of plant seedling culture, and particularly relates to a method for large-area large-scale planting of taxus chinensis.
Background
The yew is Taxaceae, also known as a yew, and the traditional plant breeding (seedling) methods include the following:
seed seedling culture: most of plant seeds with hard shells need to be dormant for hundreds of days or even longer to germinate, otherwise, the seeds can only germinate in the bamboo hat year after direct seeding in the same year, and the method for breaking the dormant period generally adopts sand storage treatment in autumn and winter, soaking before seeding and sowing in spring, but for rare plants such as taxus chinensis, the method still needs sand storage treatment in 27 months after repeated experiments, and only a few of the seeds germinate.
Cutting and seedling raising: and after the plant stops growing in dormancy, cutting annual branches into cutting slips with required length, storing the slips in sand, and cutting after the air temperature of the bamboo hat rises again in spring in the next year. However, the plants such as the taxus chinensis which are difficult to root have little possibility of survival, and the rooting rate can only reach about 5 percent even if the plants are treated by rooting powder before cuttage.
Grafting and seedling raising: the method can be used for completing the propagation of plants by carrying out sand storage treatment on plant species cut in autumn and winter, adopting a 'grafting' or 'grafting' method before the germination of the bamboo stock of the bamboo hat plants in the bamboo hat years, or carrying out 'grafting' by using leaf buds after the summer plants enter a secondary short dormancy stage. But the unique drug content of the root of the taxus chinensis, the breeding mode is only suitable for breeding ornamental varieties or collected branch and leaf varieties.
