First, after a long period of growth and field management, the Qinggu Village has experienced a serious decline in drainage and irrigation functions in most trenches in the garlic field. With the arrival of the rainy season, especially during the late growth period of garlic, there is an increase in rainwater. Blocks are prone to waterlogging and affect garlic growth. 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.
Second, to strengthen the water management With the garlic into the water demand critical period, coupled with the increase in temperature and windy weather increased, the garlic's demand for water increased, all localities should pay attention to garlic water management, general irrigation garlic head 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.
Third, supplement fertilizers The key period for garlic to absorb fertilizer is garlic sprout elongation to garlic inflating period. 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.
Fourth, prevention and treatment of pests and garlic in the late growth of prone to soft rot, leaf blight, rust and other leaf diseases. 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.
V. timely harvesting one is timely harvest 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.
