Embodiment 1

[0024] The best time to pick yew seeds is in mid-October, and the seeds are collected when the fruits are dark red. After screening, mix the seeds and plant ash in a ratio of 1:10, put them in a nylon bag and seal them for 1 day, then soak the bag in water, wear rain boots and step on it, pour the seed ash mixture into a sieve and wash it with clean water to remove the outer skin of the seeds and plant ash.

[0025] Soak the above-mentioned seed-removed seeds in warm water at 45°C for one day, put them into a dustpan, and pour them with warm water at 40°C every morning and evening. After 3 days, they should be shaded and stored in a pit with sand, and turned up and down once a day at noon. And pour a small amount of water to make it evenly heated, which is conducive to germination.

[0026] Take it out in March of the next year, soak the seeds in a mixture of alcohol and 45°C warm water (volume ratio 1:2) for half an hour, and then soak the seeds in 100mg / L gibberellin for 1 ...

Embodiment 2

[0028] The best time for yew seeding is late October, and the seeds are collected when the fruit is dark red. After screening, mix the seeds and plant ash in a ratio of 1:10, put them in a nylon bag and seal them for 1 day, then soak the bag in water, wear rain boots and step on it, pour the seed ash mixture into a sieve and wash it with clean water to remove the outer skin of the seeds and plant ash.

[0029] Soak the seed-removed seeds in warm water at 40°C for one day, put them in a dustpan, and pour them with warm water at 45°C every morning and evening. After 3 days, they should be shaded from the sun and stored in pits with sand. Turn them up and down once a day at noon. And pour a small amount of water to make it evenly heated, which is conducive to germination.

[0030] Take it out in March of the next year, soak the seeds in a mixture of alcohol and warm water (1:2 volume ratio) at 40°C for half an hour, and soak the seeds in 500mg / L gibberellin for 1 day to break do...

Abstract

The invention discloses a method used for shortening nursery stage of taxus mairei seeds. According to the method, taxus mairei seeds at a certain maturation stage are collected; accelerating germination is realized by subjecting the collected seeds to seed coat artificial delaminating, variable temperature laminated storage and hormone treatment; and when 25% of the collected seeds are sprouted, the collected seeds are sown. Normal germination of the collected taxus mairei seeds can be realized in a next spring, germination of the seeds using the method is one year earlier than that using existing taxus mairei seed germination technology, nursery stage is shortened from 18 months to 6 months, and time period needed by germination of taxus mairei seeds is shortened greatly.

Description

technical field [0001] The invention relates to the technical field of yew artificial cultivation, and more specifically relates to a method for shortening the seedling cultivation period of southern yew seeds. Background technique [0002] Yew is a rare and rare anti-cancer plant recognized in the world, and southern yew is one of the unique tree species in the subtropical to warm temperate zone of my country. It is produced in the south of the Yangtze River Basin in my country and is a first-class protected plant in China. Yew is a high-quality high-grade industrial and carving material, a beautiful tree species for urban and rural landscaping, and an excellent raw material for biological pesticide preparations. The stems, branches, leaves, and roots can be used as medicine. Golden pine biflavonoids, volatile oil, etc., known as the golden tree and plant giant panda. It integrates medicinal value, landscaping value, biological pesticide value, and high-quality material va...
