Strengthen the management of garlic in the middle and late stages of growth
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 The precipitation in Xuzhou City is still relatively low this spring. With the critical period for garlic to enter water demand, coupled with the increase in temperature and the increase of windy weather, the demand of garlic for water is increasing. Local governments must pay attention to the management of garlic moisture, and the garlic should be widely irrigated once. water. 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, yellow-white streaks can penetrate the entire leaf, and when the humidity is high, the diseased part is yellow-brown and soft rot. For the prevention and treatment of the disease, copper hydroxide and copper citrate must be sprayed as early as possible. Leaf blight frequently occurs at the tip of the leaf, showing a small white dot at the beginning, and an irregular or oval gray to grayish-brown lesion after expansion, with a black mould on top. Prevent and treat the disease. Pay attention to the timely drainage after the rain. In the early stage of the disease, timely spray fungicide such as chlorothalonil and metalaxyl manganese zinc. The rust disease department often has raised brown spots, and the orange peel is dispersed after the epidermis ruptures. Prevention and treatment of the disease should be paid attention to in order to prevent flooding and flooding. In the early stages of the disease, drugs such as triadimefon should be promptly sprayed.
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.
