Sowing date and sowing methods listed Yunnan garlic bolt most at the end of July to the October batch sowing. Early sowing garlic during high temperature hot weather, is not easy to germinate, because hot easily sharper, and do not germinate, to low temperature treatment. The garlic with the gauze dipped in the deep well lifting a day, or after the release of cold water immersion in the cold cave, two weeks after the discovery of garlic root when the mouth has been sown immediately. The other time, the wet seed is earlier than the dry seed.
When sowing should leave by garlic with seed dormancy. Garlic mark dormancy period are: garlic root bud bud protrusions appear, elongation, appear cavity between the coleoptile and new leaves. Garlic should be strictly selected, retained a large head and small, neat flap flap garlic; elimination of disability, rotten flap, dry, weak, and no bud clove moth, garlic root. The selected kinds of garlic should be broken up, remove stems, stems, heels (trays) and broken valves. Stems and heels must be removed, otherwise it will affect the water absorption, rooting and young growth.
According to the experiment, a garlic stripped of the foreskin, seedling fast and uniformly, but the amount of labor is too large and easy to pull the injured mother flap, it is generally with prepuce seeding.
In the seed to be graded, where a hundred grams of weight, about 500 grams for a level, 100 grams of weight, about 400 grams of two, and 300 grams of about three. Production as far as possible with one or two species, eliminated three species. This is due to garlic in the germination period and seedling period need nutrition mainly from the mother valve, only the mother of large, storage nutrition more, grow seedlings just healthy. So the selection to choose the big head, big flap can choose, robust early emergence, emergence, seedling, strong growth potential, high yield of garlic and garlic. After the experiment, three kinds of garlic than a garlic cut 70% garlic, garlic 12.3%. More heavy hundred petals garlic, the garlic and garlic yield still increased, but the yield increasing effect and increase the amount of nearly offset, it is generally not used. These grades refer to the large petal type of garlic, and the smaller petal type garlic is still the bigger the better. When sowing, should be planted according to level separately, one kind of garlic should be slightly diluted, two should be a little thick. This is conducive to rational close planting and unified management. After the same break, respiration was enhanced, the accumulation of too thick easy to heat injury, should pay attention to stand in the shade. The aerial bulbs of garlic can also be used as seed. After harvest should be heat, moisture. Before sowing seed, the first year can form the head of garlic, can be used in general.
