Embodiment Construction

[0013] Below the embodiment of the present invention is described further:

[0014] A method for growing seedlings of Chinese torreya, the steps are as follows:

[0015] (1) Seed collection: choose a torreya tree with thin shells and full seeds, which will grow robustly. Generally, the fruit arils turn from green to yellow-green in early and mid-September, when most of the arils crack and a small amount of seeds fall off. After collection, stack them in a cool and ventilated place (the pile thickness is 10-15 cm to prevent heat and rot), so as to facilitate the separation of seeds and arils. After about 7-10 days, when the aril is slightly purple, the seeds are taken out, and the pre-sowing treatment can be carried out. (2) Pregermination: Store in wet sand to complete physiological post-ripening and achieve the purpose of pregermination. Because the greater the temperature difference between day and night in the storage of torreya, the stronger the germination potential an...

Abstract

The invention relates to a Chinese torreya seedling raising method. The method mainly solves the problems of difficulty in Chinese torreya reproduction, low afforestation survival rate and low seedling growth speed in the prior art. The method is characterized in that the method comprises the following steps of collecting seeds (1), accelerating germination (2), raising seedlings (3) and grafting (4). As the technical scheme is adopted, Chinese torreya seed accelerating germination technology is improved, improved variety, rapid propagation, fast growing and early fructification are realized, and the Chinese torreya afforestation survival rate is effectively improved.

Description

technical field [0001] The invention relates to a technique for raising seedlings, in particular to a method for raising seedlings of Chinese torreya. Background technique [0002] Torreya torreya is an excellent species of Torreya grandis in the genus Torreya (Taxaceac). It is a rare dried fruit unique to my country and has been cultivated for more than 1000 years. Its main producing area is in Zhejiang, where there are about 21,000 mu of forests in Zhejiang Province, with an annual output of 1,200-1,500 tons. For a long time, due to the difficulty in the propagation of Torreya torreya, the low survival rate of afforestation, the slow growth of seedlings, and the delay in putting into production have not been resolved, which have seriously affected the development of Torreya torreya, resulting in the phenomenon of scarce resources, high prices, and short supply in the market. Contents of the invention [0003] In order to overcome the deficiencies in the background techn...
