Preparation of fruits and vegetables before seeding
Before sowing, carefully pick seed removal, seed, and drying in the sun for (summer not on cement ground to bask in, to prevent high temperature scald disinfected seeds). And then washed with water several times to wash away the seed seed, further impurities on the surface and adsorbed on the surface of the bacteria seed. Finally, to different time according to the different seed soaking work. Soaking time must be appropriate, too long or too short is not conducive to seed germination.
Tomato seeds, chilli seeds, eggplant seeds in normal temperature with 10 ~ 12h. Specific soaking time also according to actual circumstances, such as tomato seed when hair removal treatment, the soaking time can be less than no hair removal of Seed Soaking with 1 ~ 2h. Some seeds have dormancy period, such as the new production of cucumber, celery, pumpkin seeds for other, more soaking for several hours, and cleaning a few times, or with gibberellin hormone treatment, in order to facilitate the germination. Different water temperature required by the soaking time is not the same. After seed soaking seeds in general to rinse with clean water, some of the seed also scrub, to clear the seed surface mucus, such as eggplant, black seed pumpkin and watermelon species. After seed soaking seeds in the best indoor clothes 10 ~ 20min, the seed surface slightly dry, Eli seed coat permeability. For seedless watermelon seed and seed coat of thick watermelon seeds, adopt a new black seed pumpkin seeds, watermelon rootstock 90A, 90B seeds, such as cracking the shell after soaking, can significantly improve the seed germination rate and germination.
