Problems solved by technology

[0003] However, the dormancy period of yew seeds is longer, and it needs two winters and one summer to germinate under natural conditions, and a large number of seeds will lose their vitality during the dormancy period, so they are directly sown with yew seeds, and the germination rate is very low, which limits Artificial cultivation of yew

example 1

[0030] A method for accelerating germination of yew seeds, comprising the following steps:

[0031] Step 1, put the yew seeds into 0.1% mercury solution and soak for 20 seconds, then wash with water for 3 times, then soak the yew seeds in 0.1% potassium permanganate solution for 10 minutes, Then wash with water 4 times;

[0032] Step 2, soaking the yew seeds obtained in step 1 with a 0.3% gibberellin solution for 24 hours;

[0033] Step 3: Mix 50 parts by weight of rice bran with 50 parts by weight of sawdust, then mix in 1 part by weight of fermenting agent, pile them up into stacks for fermentation, and after 5 days of fermentation, bury the yew seeds obtained in step 2 into the stacks In, take out after 5 days; Wherein, fermented bacterial agent is mixed with the weight ratio of 1:1:10 by Bacillus subtilis, brown sugar and water;

[0034] Step 4, get the vermiculite, wet it with a 0.05% gibberellin solution with a mass fraction, then pack it into a plastic bag, and polish...

example 2

[0042] A method for accelerating germination of yew seeds, comprising the following steps:

[0043] Step 1, put the yew seeds into 0.1% mercuric chloride solution and soak for 40 seconds, then wash with water for 5 times, then soak the yew seeds in 0.1% potassium permanganate solution for 15 minutes, Then wash with water 6 times;

[0044] Step 2, soaking the yew seeds obtained in step 1 with a 0.3% gibberellin solution for 48 hours;

[0045]Step 3: Mix 50 parts by weight of rice bran with 50 parts by weight of sawdust, then mix in 2 parts by weight of fermenting agent, and pile them up into strips for fermentation. After 7 days of fermentation, bury the yew seeds obtained in step 2 into strips In, take out after 7 days; Wherein, fermented bacteria agent is mixed with the weight ratio of 1:1.5:15 by Bacillus subtilis, brown sugar and water;

[0046] Step 4, get the vermiculite, moisten it with a 0.05% gibberellin solution with a mass fraction, then pack it into a plastic bag,...

[0054] A method for accelerating germination of yew seeds, comprising the following steps:

[0055] Step 1, putting the yew seeds into 0.1% mercury chloride solution and soaking for 30 seconds, then washing with water for 4 times, then soaking the yew seeds in 0.1% potassium permanganate solution for 12 minutes, Then wash with water 5 times;

[0056] Step 2, soaking the yew seeds obtained in step 1 with a 0.3% gibberellin solution for 36 hours;

[0057] Step 3: Mix 50 parts by weight of rice bran with 50 parts by weight of sawdust, then mix in 1.2 parts by weight of fermenting agent, and pile them up into stacks for fermentation. After 6 days of fermentation, bury the yew seeds obtained in step 2 into the stacks In, take out after 6 days; Wherein, fermented bacterial agent is formed by mixing Bacillus subtilis, brown sugar and water with the weight ratio of 1:1.2:12;

[0058] Step 4, take the vermiculite, wet it with a 0.05% gibberellin solution with a mass fraction, then pa...

Abstract

The invention provides a Chinese yew seed pregermination method. The method comprises carrying out disinfection treatment on Chinese yew seeds, immersing the Chinese yew seeds in a gibberellin solution, mixing 50 parts by weight of rice bran and 50 parts by weight of sawdust, mixing zymophyte into the mixture, carrying out windrow composting fermentation for 5-7 days, burying the Chinese yew seeds in windrow, wetting vermiculite by a gibberellin solution, putting the wet vermiculite into a plastic bag, polishing the surfaces of the Chinese yew seeds by an emery cloth, putting the Chinese yew seeds into the plastic bag, sealing the plastic bag, rubbing the plastic bag once each 2-3h, wrapping the Chinese yew seeds with sponge, wetting the sponge with an indoleacetic acid solution, putting the wrapped Chinese yew seeds into a pressure tank, carrying out maintenance at a temperature of 20 DEG C under pressure of 8MPa for 15-20min, then carrying out maintenance at a temperature of 30 DEG C under pressure of 5MPa for 10-15min and then carrying out maintenance at a temperature of 40 DEG C under pressure of 1MPa for 10-15min. The Chinese yew seed pregermination method can end Chinese yew dormancy and improve a germination capacity.

Description

technical field [0001] The invention relates to the field of yew artificial cultivation. More specifically, the present invention relates to a method for accelerating the germination of yew seeds. Background technique [0002] The branches, leaves and bark of Taxus chinensis contain paclitaxel and other anticancer active substances, which have good medicinal development value and economic value. In order to ensure the sufficient and stable supply of paclitaxel and reduce the damage to wild yew, artificial cultivation of yew must be carried out. [0003] However, the dormancy period of yew seeds is longer, and it needs two winters and one summer to germinate under natural conditions, and a large number of seeds will lose their vitality during the dormancy period, so they are directly sown with yew seeds, and the germination rate is very low, which limits Artificial cultivation of yew. Therefore, it is urgent to design a method for breaking the dormancy of yew seeds, impell...
