Problems solved by technology

And because its male flower and hermaphroditic flower are dioecious, pollination is comparatively difficult, is not easy to bear fruit, and natural regeneration is poor, adds the impact of human activities (logging or as firewood), makes its population number to decline trend, if not protected, just There is a possibility of further becoming a rare or endangered species
At present, the low natural reproductive efficiency of silver magpie tree makes its species and quantity limited to a certain extent, so it is of great significance to artificially raise seedlings
Judging from the literature records, there are still relatively few studies on the artificial seedling cultivation of the silver magpie tree.

Embodiment 1

[0022] A method for releasing the dormancy of silver magpie tree seeds and improving the survival rate of seedlings, specifically as follows:

[0023] In the fruit ripening season of the silver magpie tree, the fruit with large fruit, bright color and full grain is collected from the mother plant with good fruit performance and no pests and diseases. After a period of drying, the shriveled peel is removed, and the fruit with full grain, Glossy seeds are for subsequent use; Then spread the collected seeds in a ventilated and cool place, dry in the shade for 15 days, wash the collected seeds with warm water 2 times, and then use 7% KH 2 PO 4 Soak the solution for 7 hours, then soak in 0.1% potassium permanganate solution for 4 hours, then soak the seeds in 50% sodium chlorate 50 times solution for 3 hours, and then wash the seeds with sterile water 2 times to obtain disinfection.

Abstract

The invention discloses a cultivation method for releasing dormancy of tapiscia sinensis seeds and improving the survival rate of growing seedlings. The method is achieved mainly through seed selection, seed sterilization, ultrasonic treatment, hormone and varying temperature stratification treatment, seed growing seedling soil management and other steps. With utilization of growth regulator control and the varying temperature treatment and other seed dormancy breaking technologies and with use of a suitable-concentration growth regulator and an appropriate varying temperature treatment matrix, the germination time of the tapiscia sinensis seeds is greatly shortened. Moreover, by employing an appropriate temperature, illumination treatment, the appropriate growing seedling matrix and a scientific soil management mode, the survival rate of the growing seedlings is allowed to be quite high.

Description

technical field [0001] The invention relates to a method for releasing seed dormancy and improving seedling survival rate, in particular to a method for releasing silver magpie seed dormancy and improving seedling survival rate. Background technique [0002] Silver magpie tree, also known as gall pepper tree, is scattered in the Yangtze River Basin of my country. Due to the long interval between fruiting, weak natural regeneration ability, and natural forest trees being cut down, the number of plants is decreasing day by day. Silver magpie tree is a unique ancient tree species in the subtropical flora of China. It is a third-level protected plant in China and has certain scientific value for the study of China. The wood is light and soft, straight in texture, smooth in planing, easy to rework, and can be used as furniture and panels. It has lush branches and leaves, beautiful tree shape, bright-colored fruit, light wood material and beautiful texture. It is not only an exc...
