Selection of early-maturing small valve species, such as Ershui early, Caozhou early 薹 1 and so on. Before cultivation, the seed plate should be removed, divided into three grades according to large, medium and small; the garlic seeds are soaked in the well water for 12 hours, and the condition can be treated at low temperature of 0 °C ~ 4 °C for 14 days to break the garlic. Sleep. Before planting and sowing, apply sufficient base fertilizer. Generally, apply moderately fertile manure 5,000 kg, urea 20 kg, phosphate fertilizer 50 kg, potassium sulfate 15 kg or ternary compound fertilizer 50 kg; in the case of applying the base fertilizer and leveling the land Sowing from late July to late August; general spacing is 2 to 3 cm square, and garlic is used for 600 to 750 kg; when sowing and planting, garlic cloves can be sprinkled into the clams, according to the spacing, hands are used together, Cover the soil and prevent the garlic cloves from falling over. Field management immediately after sowing, watering, small water slow pouring, watering after covering the soil 1 time; after 3 to 4 days, watering the second water, and applying 20 kg of potassium sulfate with water, pouring water every two days after fertilization, even Pour 3 water; cover the soil again when the seedling height is 20 cm. In the early stage of cultivation, the garlic seedlings are in the high temperature season. They can be used for a one-meter-high flat shed. The shed is covered with a sunshade net. It is covered every day before 8:00 am, and after 5 pm, the weather is cooled and it is no longer covered. Harvesting can be harvested once at harvest, or every 10 to 15 days at a height of 15 cm. Each time a knife is used to chase urea and water.
