Garlic pest control technology

First, the common pests of garlic pests are root mites, onion horses, stalks, scorpions and so on. Control method: Apply fully decomposed organic fertilizer as base fertilizer, and the garlic and fertilizer should be properly separated. Do not stick the garlic on the fertilizer. In places where the root damage is serious, it can be dissolved in 50 kg of water with 90% crystal trichlorfon 750 g, and then sprinkled on 750 kg of soil, and mixed after application. At the same time, when suffering from root mites and cockroaches, the base can be sprayed with 90% crystal trichlorfon 1000 times. If onion horses and stalks are used, it can be sprayed with insecticides. 2. Garlic diseases 1. Leaf blight The disease is a fungal disease, and the bacteria mainly overwinter on the diseased body. Rainy and high temperature, excessive nitrogen fertilizer, too luxuriant, long and weak seedlings are very easy to develop. Pathogens infect leaves and pedicels, usually starting from the tip of the leaf and gradually expanding downward. The newborn is a white round spot, which is enlarged to a dense black powdery mildew layer. The last leaf and the stem become yellow and die, and are broken from the diseased part. When the disease is serious, garlic is not easy to convulsion. Control methods: (1) Strengthen field management and improve disease resistance of plants. (2) Remove the diseased body after harvest and concentrate on treatment. (3) Spraying 75% chlorothalonil wettable powder 600 times night, or 70% mancozeb wettable powder 500 times.
2, gray mold disease is a fungal disease, mainly harmful to the leaves, mostly occurs in the late growth stage of the plant, the lesion is initially watery, followed by white or taupe, after the lesion is expanded into a fusiform or elliptical Gray-white large spots, half-leaf or even whole leaf surface auburn-like villi-like mold layer, tissue dry and easy to pull up. The bacteria overwinter in the mycelium state on the soil or sick body. After garlic infects the disease, it often causes the petiole and underground garlic to rot. Control methods: (1) Strengthen field management, rational close planting, and timely remove waterlogging after rain. (2) Increase the application of phosphorus and potassium fertilizer to improve the disease resistance of plants. (3) In the early stage of the disease, spray 70% mancozeb WP 500 times, or 50% keering WP 1500-2000 times.

Flexible Grinding Wheel T27

The excellent softness and sharpness of the flexible grinding wheel make it particularly suitable for curved surface processing. While it has sufficient grinding capacity, it also has the same finishing and polishing capabilities as sandpaper discs. This type of grinding wheel has good durability and cost-effectiveness. The flexible substrate and rubber can prevent vibration from being transmitted to the hands of the operator, thereby reducing fatigue. Because rubber is used between the grinding wheel and the base, the absorption capacity is higher than that of traditional paper flaps or flexible grinding wheels, and dust, dust, noise and vibration are extremely low. In addition, the flexible grinding wheel has high structural strength and hardness, good wear resistance, and can grind and polish the workpiece according to the deformation of the workpiece, ensuring the surface quality and contour accuracy and consistency of the workpiece‌12.
Compared with traditional grinding wheel grinding, flexible belt grinding also has the advantages of simple equipment, easy operation, large grinding ratio and good surface quality.
