Embodiment 1

[0025] An artificial propagation technique of southern yew, comprising the following steps: A: Seed collection and germination acceleration, the best time for seed collection is mid-to-late October, when the fruit is dark red, the seeds are collected, and after harvesting, the seeds and plant ash are mixed at a ratio of 1:10. Mix them in proportion, put them into a nylon bag and seal them for 1 day. The next day, soak the bag in water and step on it with rain boots. After stepping on it, pour the seed ash mixture into a sieve and wash it with clean water to remove the seed skin and plant ash. Choose a dry place in the shade without water accumulation. Pit, spread a layer of plain sand in the pit, sterilize the seeds mixed with carbendazim, mix them with plain sand at a ratio of 1:2 and put them into the pit, cover with plastic film to keep warm, the seeds are physiologically post-ripening and need to go through two winters One summer's wet sand storage can germinate; B: arrange...

Embodiment 2

[0027]An artificial propagation technique of southern yew, comprising the following steps: A: collecting seeds to accelerate germination, the best time for collecting seeds is in the middle and late October, when the fruit is dark red, the seeds are collected, and after harvesting, the collected seeds are soaked in a temperature of 45°C. After soaking in warm water for one day, put it in a dustpan, and then pour it with warm water at 40°C every morning and evening, take it out after 3 days, choose a dry place with no water in the shade to dig a pit, sprinkle a layer of plain sand in the pit, and mix the seeds with more After germination, mix it with plain sand at a ratio of 1:2 and put it into the pit, cover it with a plastic film to keep it warm, turn it 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. Take it out in March of the next year , Soak the seeds in alcohol and 45°C warm water (1:2) for half...

Abstract

The invention discloses a taxus chinensis var mairei artificial propagation technology, and belongs to the scientific and technological field of rare plant protection. The taxus chinensis var mairei artificial propagation technology aims to solve the problems that taxus chinensis var mairei is complicated in growth characteristic, low in growth speed under natural conditions and poor in regeneration capacity. Through countless tests for many years, taxus chinensis var mairei artificial propagation key indicators are captured, the survival rate, the propagation speed and the growth speed of taxus chinensis var mairei seedlings are improved, and the taxus chinensis var mairei artificial propagation technology is made to reach the domestic advanced level, wherein a hard-branch mass production type cutting technology fills up a provincial blank.

Description

technical field [0001] The invention relates to an artificial propagation technique of the southern yew. 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. Biflavone, volatile oil, etc., known as the golden tree, plant giant panda. It integrates medicinal value, landscaping value, biological pesticide value, and high-quality material value, and has extremely high development and utilization value. In recent years, with the increasing scarcity of yew resourc...
