Garlic management technology
Management of the turning green period After the garlic turns green, it should be watered and fertilized in time. Combined with watering and topdressing, 20 kg of diammonium phosphate per mu or 25 kg of ternary compound fertilizer is applied, followed by shallow hoeing to loosen the soil to increase the temperature and protect the moisture. Before and after the Qingming Festival, the leaves have yellow tips, and the second topdressing should be carried out in time, and the watering frequency should be increased. Generally, it should be watered every 10-15 days to promote plant growth.
Management of the growth period of garlic sprouts In early May, garlic sprouts begin to differentiate. After the beginning of summer, garlic sprouts will enter a vigorous growth period. This period requires more fertilizer and water management. When the garlic sprouts do not stick out of the leaf mouth, the third top dressing should be carried out, and 25 kilograms of ternary compound fertilizer should be applied per mu. After the garlic sprouts extend out of the leaf mouth, they should be watered continuously to promote the sprouts, and the garlic sprouts should be bent before and after the mango seeds are planted, and the sprouts should be lifted in time.
Management of the bulb swelling period After harvesting, the garlic cloves begin to swell, and the water demand increases. It is necessary to water in time to keep the soil moist and prevent premature aging; stop watering 5-7 days before the garlic harvest to prevent excessive soil moisture and the garlic cloves from rot. The garlic is loose.
