Method for growing seedlings of cephalotaxus oliveri seeds

Abstract

The invention relates to a method for growing seedlings of cephalotaxus oliveri seeds. The method specifically comprises the following steps: selecting mature cephalotaxus oliveri seeds of which the episperm is grey and slightly claret-colored; accumulating the seeds for 5 days, turning and accumulating for 5 days again, kneading to remove the episperm, cleaning by using clear water, and drying; removing moldy seeds; arranging the selected seeds on an electric field treatment rack, starting an electric field generator with the voltage of 10 kilovolt, and treating 8 minutes; accumulating and storing the seeds according to a ratio 3:1 of the sand to the seeds by using the sterilized clear water sand for 6 months; screening the seeds after beginning of spring, soaking the seeds for 2 hours by using a Guoguang rooting agent and a carbendazim mixing solution, taking the seeds out and drying for later use; laying a black plastic film on the finished seed bed, seeding the seeds in soil, arching through bamboo skin and covering the film; and checking the damage caused by rats and emergence conditions in the period of waiting for emergence. By adoption of the method for growing seedlings of the seeds, the emergence rate of the seeds is about 40 percent higher than the emergence rate of seeds which are not subjected to electromagnetic field treatment, the survival rate of the seedlings is extremely high, and the method is suitable for large-scale planting needs.

Description

technical field [0001] The invention relates to a method for growing seedlings of twig spruce seeds. Background technique [0002] Twisted clover is a species under the genus Cerniciaceae, and it is an endangered species under the national second-class protection. Because its leaves are arranged like Chinese scorpions, it is named as scorpion clover. Four alkaloids can be obtained from clover clover, one is high ketone alkaloid, No special activity; the other three are crude torretinoids, of which harringtonine and homoharringtonine have the activity of engaging in leukemia, while harringtonine itself has no significant biological activity. Therefore, the medicinal value of castor birch cloverleaf is quite high. [0003] However, under natural conditions, the germination and growth rate of the seeds of Castoria chinensis is very low, and the seedlings formed by the seeds are very few, so it is difficult to regenerate naturally. In addition, the human-made logging and the ...
