1, species selection. In order to achieve the goal of early maturity, high yield, and long duration of supply, it is better to select early-maturing, second-fruited buds with early roots, leaves that are tender and have less wax powder. For example, Gentingo in Chengdu, Ershui early, Chongming garlic in Shanghai, and Quanzhou meat and garlic in Guangxi. 2, sowing. Whether in open or protected areas, they are made of 1.5 to 1.7 meters wide flats. The internal organic fertilizer, 3,000 kilograms per acre, is shallowly turned 10 cm. In order to advance and prolong the time for the market of garlic sprouts to be continuously supplied to the market, localities must take advantage of the characteristics of early sprouting and early rooting of buds, take early treatment, try to sow early, and harvest early. The Yangtze River valley is in hot weather from June to August, so garlic cloves have to be soaked and treated with low temperature to promote the early sprouting of garlic. Treatment methods are: 1 soak the garlic cloves in well water for 1 day and night, but soaking time can not be too long, so as not to cause species flap rot. 2 After soaking, peeling garlic peels can be harvested about half a month earlier. 3 Peel the peeled garlic clove with water, remove it and place it in the cellar immediately. Maintain a temperature of 15°C and a certain humidity to make it root in a more confined environment. After about 10 days, most of the clove will be made Root can be sown. 4 Soak in clean water or urine for 1 day and night and spread evenly on the wet ground or wet grass. Cover the wet grass with a thin cover; promote early budding and hair rooting. 5 After the garlic flaps are wetted, they can be stored in a refrigerator or freezer under conditions, and treated at a low temperature of 2 to 4°C for 2 to 4 weeks to promote the activity of the enzymes in the valve flap so that budding and hair rooting can occur early. Seedlings emerged early and neatly after sowing and can be harvested 15 to 20 days earlier. The sowing density should be based on the characteristics of the variety and the sowing time. For example, the variety is selected as Yunding Zaoju, summer solstice to great summer sow, the density is 4 to 5 cm dense planting, 2 months after sowing selection; the species selection of the second water is early, the beginning of autumn to the summer heat cultivation, plant spacing of 6 to 7 cm or dislocation plant, 70 Harvested around days. When sowing, close the garlic seeds vertically in the pods. After sowing, cover the soil 3 cm above the ground, then spread the soil 1 to 2 cm after irrigating the water, cover the seed with straw better. (3) fertilizer and water management. If the soil is too much after sowing, it must be immediately irrigated to moisten the soil to ensure that the garlic sprouts emerge early and are neat. After the seedlings are thin, the quick-acting fertilizer is applied once to raise the seedlings, and the second time the fertilizer is applied within 40 days after sowing. If the soil is dry, the topdressing fertilizer is then re-irrigated once for seedling promotion. Slope can not be irrigated, top-dressing should be diligent, to be light, to more, in order to maintain the soil moist, conducive to the growth of garlic sprouts. (4) Harvesting. After garlic grows to 20 centimeters or more, it can be collected in batches in batches, or harvested in septa, and then topdressed for growth. The method of harvesting is generally one-time uprooting and washing the mud and debris. It can also be picked on a sunny day with a knife cutting at 3 cm from the ground. After harvesting, the fertilizer and water management will be strengthened. In this way, two harvests can increase the yield per mu from 2000 kg to 3500-4000 kg. China Agricultural Network Editor
