Hydro-priming method for Chinese pine seeds

Abstract

The invention discloses a hydro-priming method for Chinese pine seeds. In the method, the Chinese pine seeds are put in a plastic plate for priming seeds, and under dark conditions, the temperature of a working room is controlled to 10 DEG C; during the seed priming period, after 0h, 8h, 16h, 40h, 64h and 88h, based on the total water absorption amount, 53.6 percent, 14.5 percent, 14.5 percent, 8.3 percent, 5.7 percent and 3.4 percent of water are added into the plastic plate respectively, wherein the total addition amount of water is 30 percent based on the original mass of the seeds, and the priming period is 10 days; during the priming period, the plastic plate is periodically and fully stirred to guarantee the uniform water absorption of the seeds; and the treated seeds can be directly used for sowing, or re-dried for storage. The method has the advantages of obviously improving activity and resistance of the Chinese pine seeds and the seedlings burgeoned by the Chinese pine seeds, solving the problem that the seed quality is low, the problem that the burgeoned seedlings are weak in activity and resistance, the problem that the seeds cannot be stored again, and the problem that the seedling survival rate of the seeds is low when the seeds are used for direct seeding forestation or air seeding forestation in the Chinese pine seeds treated by the conventional seed-soaking sprouting, along with simple method, easy mastering of the technique, low seedling-growing cost and easy popularization.

Description

technical field [0001] The invention belongs to the technical field of pre-sowing treatment of plant seeds, and relates to an initiation method for afforestation and greening tree species, in particular to a method for water initiation of pine seeds. Background technique [0002] At present, the global desertification area has reached 36 million square kilometers, accounting for 1 / 4 of the entire earth's land area, which seriously threatens the survival and development of human beings. Live afforestation has the advantages of fast speed, labor saving, low cost, wide range, and is suitable for remote mountainous areas with sparsely populated areas and difficult artificial afforestation. It has become an important way for the world to control desertification. [0003] Pinus tabulaeformis is an evergreen tree in the warm temperate zone. It has beautiful tree appearance, evergreen seasons, excellent material, drought resistance, cold resistance, and barren resistance. It has hig...
