Soil-borne diseases and insect pests such as Phytophthora capsici root rot, Pythium root rot, eggplant verticillium wilt, melon root-knot nematode are aggravated in some areas, which often leads to severe yield reduction. In addition, the perennial heavy sputum caused the deterioration of the soil environment, and the self-toxic effect was obvious, which seriously inhibited the growth of the sorghum vegetables. Soil disinfection is an important method to control these soil-borne pests and diseases. Reasonable choice of soil disinfectant With the increasing emphasis on soil disinfection by vegetable farmers, various forms of soil disinfectants have appeared on the market, such as methyl bromide in gaseous form, cotton granules in granular form, lime nitrogen, Weibaimu in liquid dosage form, and chloropicrin. 1. There is a difference between the arch shed and the greenhouse. The arch shed has a large area, and the planting efficiency per unit area is relatively low, and a relatively inexpensive soil disinfectant can be selected. The arch shed has a relatively short rest period, and it should be considered to select a disinfectant with a short disinfection time. The greenhouses have a long period of rest, and should be selected according to the key points of pest control and soil quality. 2. Select soil disinfectants according to the focus of pest control. Planting greenhouses such as peppers and eggplants and plots for planting ginger. The main purpose of soil disinfection is to kill soil-borne bacteria that cause pepper root rot, eggplant verticillium wilt, ginger mites, etc. planting loofah and bitter gourd. In the greenhouse of cucumber, the main purpose of soil disinfection is to kill root-knot nematodes in the soil. Although chloropicrin has excellent killing effect on pathogens, it has a poor killing effect on root-knot nematodes; while 1,3-dichloropropene has a good killing effect on root-knot nematodes, and the two can be applied together. Scientific use of soil disinfectants 1. Fine soil preparation before applying soil disinfectant. Before applying the soil disinfectant, deep-turn it and then use a rotary tiller to swirl the ground to make the soil particles small and uniform. This will give full play to the effect of soil disinfectants to a certain extent. 2. Maintain a suitable soil moisture. The soil moisture should be kept at 60%~70% during disinfection. 3. Cover the plastic film correctly. The plastic film covered with the soil disinfectant should not be too thin, and it is preferable to use a non-permeable film (airtight) or a plastic film having a thickness of 0.04 mm or more. 4. Maintain a certain filming time. The length of filming after application is determined by temperature. When the temperature is above 30 °C, it covers 7~12 days. When the temperature is 15 °C~30 °C, it covers 12~15 days. Disclaimer: Some articles on this website are transferred from the Internet.
