Embodiment 1

[0015] A method for accelerating germination of southern yew seeds, comprising the steps of:

[0016] (1) Harvest the fresh fruits of Taxus chinensis from November 1st to November 15th every year, wash the outer testa in time within 2 days, and then dry the seeds;

[0017] (2) Mix the dried seeds and fine sand evenly at a volume ratio of 1:2, put them into a storage pit with a depth of 70cm, and set drainage ditches around the storage pit; control the moisture content to 10% during the initial three months of storage , control the moisture content to 6% in the later stage of storage;

[0018] (3) Store in fine sand until April 15th to April 30th of the next year, remove impurities from the seeds, put them in plastic containers, and soak them in warm water at 30°C for 30 hours;

[0019] (4) Take out the soaked seeds, put them in the basket, and pour them with warm water at 28°C every morning and evening, and repeat for 4 days;

Abstract

The invention relates to a pregermination method of taxus mairei seeds. The method comprises the following steps: adopting fresh fruits in November of each year; mixing the aired seeds with silver sand evenly according to the volume ratio of 1 to (2-3), and then storing in a storage pit to April 15 to 30th April in the following year; removing impurities from the seeds, putting into a plastic utensil, and soaking in warm water at 30-37 DEG C for 30-40 hours; continuously spraying warm water at 28-30 DEG C on the soaked seeds for 4-5 days; and storing the processed seeds with the silver sand again until a crack appears on a seed-case. The pregermination method disclosed by the invention is simple in steps, relatively strong in operability and relatively low in cost, and is capable of shortening the sleep time of the taxus mairei seeds, significantly promoting the germination rate of the taxus mairei seeds, and promoting the taxus mairei to grow and breed on a large area.

Description

technical field [0001] The invention relates to a method for accelerating germination of southern yew seeds, belonging to the technical field of yew artificial cultivation. Background technique [0002] Southern yew is an evergreen species of Taxaceae. It belongs to the first-class national key protected plants. Its resources are scarce and its natural reproduction and renewal ability is low. However, the social demand for it is relatively large, and it can only be carried out through large-scale artificial planting. The southern yew usually adopts seeds to raise seedlings, but its seeds are typical forms-physiologically dormant seeds. More than one year (two winters and one summer) of stratified germination treatment can relieve dormancy, and its overall germination rate can only reach 50-60%, which seriously affects the planting of southern yew species. Contents of the invention [0003] The purpose of the present invention is to solve the shortcoming of long dormancy t...
