In the summer high temperature season, it is a good way to eliminate germs, kill eggs, remove weeds, and improve the soil. The so-called high-temperature stuffy shed is the use of the sun's high temperature and drug fumigation for shed disinfection, generally from late July to mid-August. This method is low in cost, small in pollution, simple in operation, and effective in that it is easily accepted by the masses. However, it is also necessary to pay attention to the method of boring sheds. In the past few years, some peasants have not paid attention to the relevant details of the shed, so they cannot reach the sterilizing effect of the boring shed. For this reason, I hope farmers' friends should pay attention to the following points when they are in the shed. In combination with site preparation, deep-slope fertilization sites should be leveled, finely sculpted, and deep-spot fertilization should be used in combination with site preparation. By taking advantage of the opportunity for site preparation, chicken manure and cow dung should preferably be applied to the ground in order to kill pathogens in organic fertilizers at high temperatures. . Chicken manure and dried cow dung also have the effect of raising the temperature of the ground and maintaining the temperature of the ground, which can enhance the bactericidal effect. After the land has been turned upside down and flattened, ridges or high and low ridges are formed according to the planting patterns of the crops. This will create a small space between the mulch and the ground, which will help increase the ground temperature. Pouring water with enough water, increasing the moisture content of the soil is closely related to the bactericidal effect. Practice has proved that the soil moisture content is too low to achieve a good bactericidal effect. The best results are obtained when the soil moisture content reaches 60% of the maximum water holding capacity in the field. It is advisable that the irrigation surface be 3 to 5 cm above the ground. Combine irrigation with 2 kg of deep tillage fertilizer per acre to increase the permeability of the soil. Drug treatment, sterilization, insecticide, dead tree phenomenon in previous years, greenhouses, can be used between the dead tree spirit 2 ~ 3 kg per mu and 5 kg of ammonium bicarbonate mixed, spread on the ground and deep turn 10 ~ 15 cm after pouring water, also Lime nitrogen can be used to mulch the soil to kill bacteria in the soil. In addition, before sealing the greenhouse, the surface of the shed was sprayed with a germicide and insecticide to kill the bacteria and pests hiding in the wall joints. Close the greenhouse, increase the ground temperature with double-layer covering with greenhouse membrane and mulch, and strictly maintain the tightness of the greenhouse. Under such conditions, the maximum ground temperature can reach 70°C at a depth of 10 cm below the ground, and the ground temperature at a depth of 20 cm can reach 45°C. Above °C, this high ground temperature sterilization rate can reach more than 80%. Appropriately extend the time of boring the vast majority of bacteria is not resistant to high temperatures, after more than 10 days of heat treatment can be killed, such as some of the pathogens, cucumber sclerotinia, cucumber pathogens, eggplant Verticillium and other pathogens Not very resistant to high temperatures. However, some pathogens are particularly resistant to high temperatures, such as root rot pathogens, clubroot disease, and fusarium wilt pathogens. Some deep-rooted soil-borne pathogens, due to their deep soil distribution, must be processed for 30 to 50 days to achieve good results. . Therefore, when the soil is disinfected, the disinfection time should be determined according to the heat resistance of the crops and their corresponding pathogens in the shed. After the dwelling, the treatment of high-temperature boring sheds works best for soils up to 15 cm deep, and for soils more than 20 cm deep, the disinfection effect is poor. Therefore, it is best not to plough the soil after sterilizing the soil. Even ploughing should be limited. At a depth of 10 cm. Otherwise, the bacteria in the soil below will be reverted and recontamination will occur. High-temperature stuffy sheds can significantly reduce the density of germs in the field, greatly reducing the chance of crop morbidity. For greenhouses with root-knot nematodes, when base fertilizers are used after boring, avermectin organic fertilizer or organic fertilizer 400 grams of Gram-negative bacteria can be used per mu, which can basically eliminate the harm of root-knot nematodes.
