After a long period of growth and field management, the gully dredging system has severely reduced irrigation and drainage functions in most trenches in the garlic field. With the advent of the rainy season, especially during the late and late stages of garlic growth, the rainwater has increased in some areas where the gullies are not matched. Waterlogging hazards occur easily and affect the growth of garlic. In the near future, we must do a good job in clearing and digging the garlic fields to ensure that the "three ditch" facilities will be used to ensure that irrigation and flooding can be done in drought and drought, and drought will be stopped to prevent rain and waterlogging. Strengthen water management With the critical period for garlic to enter the demand for water, coupled with the increase in temperature and windy weather, the demand for garlic for water increases. Local governments must pay attention to the management of garlic water and generally use garlic to inflate water once. For some of the highland plots, appropriate amounts of water should be provided by using wells or other means to ensure the moisture requirement of garlic bulbs. Supplementary fertilizers The critical period for garlic to absorb fertilizers is the growth of garlic sprouts until the expansion of garlic bulbs. Due to the different fertilization levels, the differences in plant growth between the plots were significant, and some plots had appeared yellowing and thinning and other defertilization, and measures should be taken to supplement fertilizers. First, combined with irrigation fertilization, urea 15 ~ 20 kg per mu; the second is sprayed 0.5% urea solution, 0.3% potassium dihydrogen phosphate solution or other organic fertilizer; third is the garlic expansion in the early spraying garlic swelling agent, each Mu with 200 ml of water spray 40 ~ 50 kg. Prevention and control of pests and garlic in the middle and late growth period are prone to various leaf diseases such as soft rot, leaf blight, and rust. Among them, soft rot is a bacterial disease, and it should be sprayed with copper hydroxide, copper carboxylate and other drugs at the early stage of the disease. Leaf blight frequently occurs at the tip of the leaf to prevent the disease from being drained in time after the rain. In the early stage of the disease, fungicides such as chlorothalonil and metalaxyl manganese zinc are sprayed in time. Prevention and treatment of rust should pay attention to prevent flood irrigation, in the early onset of timely spraying drugs such as triadimefon. One timely harvest is the timely harvest of garlic sprouts. Garlic, garlic-based garlic, grows 15 to 18 centimeters in length, bends like a scale hook, and maggots expand significantly. When the color changes from green to white, it is harvested. The second is timely harvest of garlic. The dried garlic bulbs are sold at the base of the plant where the leaves are dry and the pseudo-stems are soft, and they are harvested when they are forced to one side and overwhelmed with toughness. Generally, they are harvested about 20 days after picking. Marketed Fresh Garlic, generally harvested 5 to 7 days earlier than dry garlic harvest to maintain crisp quality.
