Step 1, Because the root system of garlic is shallow and its absorption is weak, it should be convenient for irrigation and drainage, and loose sandy soil is appropriate. Generally, three plows and three rakes are used to make the land finely divided and leveled, so as to facilitate rooting and emergence. On the basis of deep ploughing and fine-tuning, it is best to start a paddy field with a width of 1-1.5 meters, a ditch width of 30 cm, a ditch depth of 25 cm, and the middle ditch and the surrounding ditch are appropriately deepened to facilitate drainage and irrigation, and 5-7 Line garlic.

Step 2. Garlic needs to be germinated and phoxim seed dressing before sowing. The trench is 10 cm deep, 6-7 cm wide, and covered with soil 3-4 cm after sowing. Sow seeds around October 10. Density of 50-55 plants per square meter.

Step 3. Garlic should be watered immediately after sowing, and then watered again after 5-6 days. After the seedlings emerge, water the third time, and then cultivating. Water in winter, hoe in time during the greening period, plough, and topdress with 3-4.5 kg of organic fertilizer and 0.05-0.06 kg of nitrogen fertilizer per square meter. During the growth period of garlic sprouts, water 3-4 times to keep the soil moist.

Stop watering five days before garlic bolting to facilitate bolting, during the period of garlic expansion, water 4-5 times, and stop watering 5-6 days before harvesting garlic to facilitate harvesting. In addition, during the growth period of garlic, the weeds on the garlic field should be removed in time, and 1.5% acetochlor should be sprayed on the ground after the garlic is sown.
The harvest of garlic is generally 24-28 days after garlic bolting, and 14-16 days after garlic bolting on clay soil. Garlic in open field is delayed by 5-10 days compared to covered garlic. At this time, the harvested garlic is not scattered and tightly held. Choose sunny days and harvest when the soil is dry. It should be dried in time after harvest to prevent the quality from being reduced.
In the selection of garlic species, try to choose varieties with strong disease resistance. If you choose high-yield varieties with weak disease resistance, in order to prevent the mother species from carrying germs, the garlic seeds must be detoxified.
Avoid continuous cropping, and avoid continuous cropping with onions, ginger, leeks and other crops. A reasonable way is to plant a season of grass crops such as corn after harvesting garlic, and implement a crop rotation pattern such as garlic-corn-garlic-corn. Severely diseased areas can be left fallow for one year.
