Problems solved by technology

Female plants 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

Embodiment Construction

[0016] A method for constructing a southern yew ear nursery for producing upright spikes, comprising the following steps:

[0017] Ⅰ. Cultivate southern yew seeds into southern yew saplings with a seedling height of 50cm to 80cm. Above-mentioned seed seedling cultivation is seed graded seedling cultivation, and this seed graded seedling cultivation comprises the following steps:

[0018] (1) Remove the sand and wash the seeds of Taxus chinensis after being stored for one year, and then classify and screen the washed seeds with grading sieves of different diameters. Preferably, the southern yew seeds are classified into three types of a1, a2, and a3 through grading sieves with two apertures of 4mm and 5mm, the seed diameter of the southern yew seeds of the a1 type is greater than 5mm, and the southern yew seeds of the a2 type are 4mm in diameter ~5mm, and the seed diameter of a3 species of Taxus chinensis is less than 4mm.

[0019] The seed diameter intervals of the southern ...

Abstract

The invention relates to a building method of a taxus chinensis var mairei cutting orchard for producing erect panicle. The method comprises the steps of removing top tips, adjusting crown bodies, bending main trunks, conducting exposure to promote germination, picking scions and conducting management after picking the scions. By means of the building method, the cutting orchard is short in development cycle, easy to operate and low in cost and well solves the technical problem of common taxus chinensis var mairei cutting seedlings that crowns easily deflect due to a position effect; meanwhile, the yield of the scions of the cutting orchard is greatly increased, the quality of the scions is greatly improved, the method has the advantages of being easy to operate, easy to popularize and thelike, meets large-area breeding and cultivation requirements and can increase the good variety breeding level of taxus chinensis var mairei.

Description

technical field [0001] The invention relates to the field of arbor cultivation, in particular to a method for constructing a southern yew ear picking nursery for producing upright spikes. Background technique [0002] Taxus was first recorded in "Northeast Medicine Plant Records", also known as Chinese cypress pine, yew, and yew pine, belonging to the genus Taxus yew. There are 11 species of yew in the world, distributed in the temperate to tropical regions of the northern hemisphere. There are 4 species and 1 variety in China, namely Chinese yew, northeast yew, Yunnan yew, southern yew, Tibetan yew, etc., distributed in northeast China , South China and Southwest China. 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 seedlin...
