First, chase fertilizer in time. In the 6-7 leaf stage, the mu should be mixed with 30-35 kg of 15:15:15 compound fertilizer and 8-10 kg of potassium sulfate. Pay attention to the first fertilization after fertilization, should not be fertilized after the first irrigation.
Second, strengthen water management. After the 7th leaf stage of garlic, the demand for water increases. It is necessary to maintain the supply of physiological water in the middle and later stages of garlic to ensure the normal supply of nutrients and ensure the healthy growth of garlic. Water management requires that the soil be kept moist, the fields should not crack, and the garlic leaves should not wilt. Generally garlic is filled with water for about 10 days.
Third, do a good job of garlic leaf blight prevention and control work. When garlic enters the 7-leaf stage, it is the weakest period of disease resistance. Since the beginning of winter this year, there has been no rainfall and drought for more than 60 days. During this period, we must promptly prevent the occurrence of garlic leaf blight. The incidence of field blocks should be promptly administered 2-3 times to control the spread of garlic leaf blight. Control methods: 30 grams of difenoconazole with 200 grams of potassium dihydrogen phosphate mixed spray. Note: The preventive drugs for garlic leaf blight must be used interchangeably.
