Forest seed collection and treatment
2019-06-04 03:03:32
The appearance of timely harvested seeds with darker color, fuller kernels, and toughness and luster are mature performances. Seeds should be harvested on sunny days. If harvesting is too early, the germination rate of under-mature seeds is low.
Selecting the mother tree to be picked depends on the species. For timber forests such as cedar, Pinus massoniana, and acacia, the medium- and early-year trees with rapid growth, straight trunks, and high quality timber should be selected as the mother trees for the seed collection; the economic forest should be selected with good results, good quality, and early maturing for the seed collection trees. Damage the trunk and shoots.
Seed processing after harvesting Seeds or fruits after harvesting should be promptly dried and shelled to remove debris and grading. Cone is harvested and exposed to sunlight or dried in a ventilated place. Remove the scales from the shell and remove the seeds. Fruit flesh, berries, etc., thick meat and water, easy to mold deterioration, immediately after harvest, smashed, washed, that is, remove the seeds, spread on the mat and dry.
Seed storage method Sealed storage Put completely dry seeds in cans, barrels, cylinders, etc., and seal them with wax. Place them in a cool place to maintain seed germination power for a long time.
The dry storage method puts fully dried tree seeds into bags, casks or tanks and is placed in a ventilated and dry room to prevent insects and rodents.
