What are the management techniques of garlic in spring?

After the sting, garlic turns green, so water and fertilize it in time. Combined with water topdressing, 25 kg ternary compound fertilizer. Subsequently, shallow hoeing was carried out to loosen the soil to raise the temperature and keep moisture. Yellow shoots appear in the leaves before and after Tomb-Sweeping Day, so it is necessary to topdressing twice in time and increase the watering times, generally once every 10- 15 days to promote plant growth.

Second, the management of young garlic shoot growth period.

At the beginning of May, garlic shoots began to differentiate. After a long summer, garlic shoots entered a vigorous growth period, during which the management of fertilizer and water should be strengthened. When the young garlic shoots do not extend out of the leaf opening, the third topdressing is carried out, and 25 kilograms of ternary compound fertilizer is applied per mu. After the young garlic shoots stick out of the leaf mouth, they should be watered continuously to promote the young garlic shoots with water. The young garlic shoots should be bent back and forth in the awn seeds and lifted in time.

Third, the management of bulb expansion period.

After bolting, garlic cloves begin to swell, and the water demand increases, so it is necessary to water them in time to keep the soil moist and prevent premature aging. Stop watering garlic 5-7 days before harvest to prevent excessive soil moisture, garlic cloves rotting and garlic loosening.

Fourth, pest control.

Purple spot and leaf blight often occur in garlic in spring. 500 times solution of 64% antiviral alum wettable powder or 600 times solution of 50% chlorothalonil wettable powder can control purple spot. 600 times solution of 70% mancozeb wettable powder or 500 times solution of 90% ethyl phosphate can control leaf blight. The main pest is thrips, and 800 times dimethoate EC can be sprayed.

Garlic planting time:

Garlic is a crop that likes cold environment, so according to the climate and varieties of each region. It can be divided into spring sowing and autumn sowing. The temperature in autumn and winter in northern China is low and relatively cold, so the seedlings can't overwinter safely and are not suitable for autumn sowing. We can plant seedlings in greenhouse, sowing in early spring and harvesting in summer.

The temperature in the south is low, and it is warm enough in autumn and winter. When sowing in autumn, seedlings can safely overwinter in the open air, so autumn sowing is the main method.
