Problems solved by technology

[0008] As a precious tree species, Taxus Mandia is mainly propagated by cuttings at present, and there are few seedlings. The main problem is that the seeds of Taxus Mandia are difficult to break dormancy and the germination rate is low. In the traditional seedling method, red bean Mandia Fir seeds need to be stored in sand for more than 18 months before they can germinate and be used for sowing. The cycle is long, and the seeds are lost due to mildew and rot. Manual regular inspection, picking, and sand replacement also increase labor costs, and the actual application effect is poor.

Embodiment 1

[0024] This method of early germination of yew seeds is carried out as follows:

[0025] The first step is to select the seeds. Pick the mature fruits of Taxus chinensis in September of that year, wash the arils and place them in a cool and ventilated place to dry in the shade. The Chinese fir seeds were soaked in 30% hydrogen peroxide for 5 hours. After the soaking, the seeds were taken out and cleaned with pure water to remove the hydrogen peroxide on the surface of the yew seeds. After cleaning, the yew seeds were placed in a cool and ventilated place to dry to obtain dried yew seeds;

[0026] In the second step, mixing, the obtained dry Taxus chinensis seeds are mixed with perlite to obtain a mixture, the ratio of the volume of Taxus chinensis seeds and the volume of perlite in the mixture is 1:3, and then the obtained The mixture is placed in an incubator for 30 days, and the constant temperature of the incubator is 4°C;

[0027] The third step, the preparation of germi...

Embodiment 3

[0040] This method of early germination of yew seeds is carried out as follows:

[0041] The first step is to select the seeds. Pick the ripe fruits of Taxus chinensis in October of that year, wash the arils and place them in a cool and ventilated place to dry in the shade. The Chinese fir seeds were soaked in 30% hydrogen peroxide for 5 hours. After the soaking, the seeds were taken out and cleaned with pure water to remove the hydrogen peroxide on the surface of the yew seeds. After cleaning, the yew seeds were placed in a cool and ventilated place to dry to obtain dried yew seeds;

[0042] In the second step, mixing, the obtained dry Taxus chinensis seeds are mixed with perlite to obtain a mixture, the ratio of the volume of Taxus chinensis seeds and the volume of perlite in the mixture is 1:3, and then the obtained The mixture is placed in an incubator for 30 days, and the constant temperature of the incubator is 4°C;

Abstract

The invention discloses a method for promoting germination of taxus media seeds in advance. The method comprises the following steps of selecting seeds, mixing with perlite, treating an accelerating germination liquid and sowing seeds so as to enable taxus media seeds to germinate in advance. The method has the beneficial effects that the taxus media seed germination by adopting the method can be earlier than that by adopting a conventional sand storage method by more than 12 months; the taxus media seeds can be sown one year in advance; in the seed storage process, the mildew and rot rate of the taxus media seeds can be reduced; the taxus media seeds can be saved; the germination rate of the taxus media seeds reaches 75%-77%, the germination efficiency of the taxus media seeds is improved.

Description

technical field [0001] The invention relates to the field of planting technology, in particular to a method for early germination of yew yew seeds. Background technique [0002] Taxus media Rehd (Taxus media Rehd) is a hybrid of Northeast Taxus and European Taxus. It is an evergreen shrub. The content of paclitaxel is 4 to 10 times that of domestic varieties, and all parts of the plant contain paclitaxel, which has a high extraction utilization rate. , plus the advantages of strong vitality and strong resistance to diseases and insect pests, it is a tree species with high utilization value. [0003] Like other plants of the genus Taxus, under natural conditions, the seeds of Taxus Mandiae need to go through two winters and one summer before they can germinate in the spring of the third year. The dormancy period is longer. There are three main reasons for the dormancy of Taxus seeds: [0004] 1. Seed coat disorder. The testa is composed of three layers: the outer testa, the ...
