How to grow garlic to get high yield

How to grow garlic to get high yield? What are the steps for growing garlic? Also ask experienced netizens to help introduce that garlic is one of the most common food in table dishes, that is, it can be eaten raw or seasoned, and it is an ideal cash crop, so the farming network has sorted out two garlic planting methods of film mulching and open air. The following detailed lists are listed for netizens' reference. First, the method of planting garlic with plastic film: step one, deep ploughing fine rake, fine soil preparation, and leveling the border surface before sowing garlic. Apply 5000 kg of organic fertilizer, 50 kg of cake fertilizer, 50 kg of diammonium phosphate and 30 kg of potassium sulfate per mu. After finishing the ground, it is made into a sewer and sunny border, which is 20-25 cm narrower than plastic film, and the ditch is 25 cm deep and 25 cm wide. Step 2, because garlic sprouting is carried out before sowing, the sowing time of covered garlic can be 5-7 days later than that of garlic cultivated in the open field, and it can be sown around October 15 with a planting density of 35000-40000 plants per mu. Step 3. Garlic planted with plastic film mulching is generally irrigated with small water, the first water is watered immediately after sowing, the second water is close to emergence, one water is watered at the seedling stage, before overwintering, one water is poured at the green stage, one water is poured at the garlic bolting differentiation stage, 3: 4 water is poured before bolting, and the watering is stopped 5-7 days before bolting to facilitate bolting. Pour 3-4 water after bolting. The bolting of garlic covered with plastic film was 5-7 days earlier than that of garlic in the open field. Garlic can not top out of the film, to artificially buckle seedlings, garlic bolting bud, can remove the plastic film, while weeding. Step 4. The main pests of garlic are onion thrips and garlic maggots. 1200 times of dichlorvos can be used to spray thrips and 1000 times of trichlorfon to kill garlic maggots. The main diseases are leaf blight and soft rot. For prevention and control, 0.5% copper sulfate solution can be used for soil disinfection before sowing; if the disease occurs, 80% chlorothalonil 800 times solution can be sprayed. Second, the method of planting garlic in the open air: step 1, because the root system of garlic is shallow and its absorption is weak, it should be convenient for drainage and irrigation and loose and fertile sandy soil. In general, three ploughs and three harrows make the fields fine and flat, so that they can take root and grow seedlings. On the basis of deep ploughing and fine finishing, the irrigated field is best to start the border, with a width of 1 to 1.5 meters, a width of 30 centimeters and a depth of 25 centimeters, and the middle ditch and perimeter ditch should be properly deepened to facilitate drainage and irrigation. 5-7 rows of garlic should be planted in each border. Step 2, garlic needs to be germinated and mixed with phoxim before sowing. The trench is 10 cm deep and 6 cm wide, and the soil is 3 cm 4 cm after sowing. Sow seeds around October 10th. The density is 35000 to 38000 plants per mu. Step 3. The garlic should be watered immediately after sowing, and then watered 5-6 days later. The seedlings should be watered with the third water, and then ploughed and hoed. Watering water in winter, hoeing and ploughing in time during the return to green period, and topdressing 2000-3000 kg of organic fertilizer and 30kg-40kg of nitrogen fertilizer per mu. During the growing period of garlic bolting, the soil was watered for 3 to 4 times to keep the soil moist. Stop watering 5 days before bolting of garlic to facilitate bolting, watering 4-5 water during the expansion period of garlic, and 5-6 days before garlic harvest. In addition, during the growth of garlic, weeds in the garlic field should be weeded in time, and 1.5% Acetochlor should be sprayed on the surface after sowing. The harvest of garlic is generally 24-28 days after bolting and 14-16 days after bolting of clayey garlic. Garlic in the open field is 5: 10 days later than film-coated garlic. At this time, the garlic harvested does not disperse and holds tightly. Choose sunny days and harvest when the soil is drier. It should be dried in time after harvest to prevent the quality from decreasing. Fertilization and watering methods of garlic Management methods in the later stage of garlic planting
