Embodiment 1

[0020] A method for constructing a spike nursery of southern yew, the steps are as follows:

[0021] (1) Selection of nursery land: Choose the site for nursery construction in dry land or farmland with deep, loose soil, rich organic matter, humidity, good drainage, and no serious pests and diseases;

[0022] (2) Soil preparation and bed making: from the winter of the first year to the middle of January of the following year, three plows and three harrows are completed on the land, the broken soil is leveled, weeds, sundries, and stones are removed, and enough base fertilizer is applied. The base fertilizer is NPK content of 1:1:1 compound fertilizer, the application rate of base fertilizer per mu is 20kg, and then 1000kg of organic fertilizer is applied per mu. The organic fertilizer is completely made from the fermentation of yew branches and leaves. Bed height 20cm, bed width l00cm;

[0023] (3) Selection of seedlings: select biennial seedlings bred from seeds of southern y...

Abstract

The invention relates to a taxus chinensis cutting orchard construction method. According to the method, a nursery land is selected at a moist dryland or farmland with deep and loose soil, high organic matter amount, good drainage, and no serious pest and disease; the land is prepared and fertilized, and is ditched for preparing beds; biennial seedlings bred from taxus chinensis seeds from high-quality provenance are selected, wherein robustly and vigorously growing seedlings with full buds an with an average seedling height of 50-55cm and an average base diameter of 0.8-1cm are selected for field planting; and managements such as shading, weeding and fertilizing are carried out in the cutting orchard. With the construction method provided by the invention, cutting orchard construction period is short, operation is simple, and cost is relatively low. A taxus chinensis large-area propagation and cultivation technical problem is well solved. With the method, taxus chinensis fine breed propagation level can be improved.

Description

technical field [0001] The invention relates to a construction method of a southern yew ear picking nursery, and belongs to the technical field of yew propagation. Background technique [0002] Southern yew is a plant of the genus Taxus in the Taxaceae family. It is mainly produced in the south of the Yangtze River Basin and is a first-class protected plant in my country. Southern yew plants are dioecious, and the pollination rate of female plants is affected by factors such as weather, temperature, humidity, and wind direction. The female plant can bear fruit, but the seed quantity per plant is very low, and the seed dormancy period is as long as 1-2 years, and the seedlings grow very slowly, which brings great difficulties to large-scale propagation and cultivation. At present, large southern yew trees are very rare. In order to preserve and continuously utilize this precious tree species, the cultivation range of southern yew will be expanded and the quality of southern ...
