For vegetable growers who grow vegetables, the pests and diseases of vegetables are the most troublesome. The use of more pesticides will have a bad effect on fruits and vegetables. The use of less insecticides is very low, resulting in the killing of pests and diseases. Endlessly, many people use the method of smuggling sheds to control pests and diseases. This is a very good way. How to properly cover the film after the shack? Take a look with Cherry Little Girl! At present, it is a critical period of soil treatment, and the effect of soil treatment determines the growth of a large number of vegetables in the future. Most vegetable farmers take measures to smear the pharmacy. The chemicals used usually include calcium cyanamide (lime nitrogen) and Weibaimu. These have good killing effects on harmful bacteria and nematodes in the soil, but they need attention. Yes, film coverage is critical when handling high temperature suffocating sheds. According to Cherry Xiaomei, although some vegetable farmers use medicinal shacks, the effect is not satisfactory, and those vegetable farmers who use the chemical treatment + ground cover film measures tend to have better stagnation effect. To this end, Cherry Xiaomei interviewed a number of vegetable farmers who were treated with medicinal shacks. Although the filming methods were different, they often received better results. How did they do it? First of all, the film should be unified . Because the application of irrigation water takes the north-south trend, the ridge is also the north-south direction. Therefore, the film is covered by the east and the west, and the film is pressed from the north to the north, and the film is pressed to the north side. This can avoid the film when watering. "Water, causing water to flow to the membrane. After the whole shed is covered with film, the method of grooving and laminating on both sides of the north and south and east and west sides should be adopted to greatly improve the sealing property of the film covering the ground and improve the fumigation effect of the medicament.  Second, the film should be tight. When the film is covered, it will not be able to proceed smoothly due to the block blocking. In this case, the film needs to be broken. It should be noted that the scratched film not only needs to be tightened with tweezers after bypassing the column, but also needs to cover the smear again with a mulch film to improve the sealing effect of the film around the column. Again, the membrane is used as little as possible. The joint between the membrane and the membrane should be as little as possible. This is because the cover soil has more to block the light from entering the soil, which will reduce the soil warming effect. The overlap between the film and the film will naturally adhere due to condensation, improving the sealing of the film. Finally, pay attention to the order of the film . Some vegetable farmers will adopt the method of first watering and then laminating. This method is not as good as watering the membrane first. Some pharmacies need to react to the water to achieve the killing effect. The method of coating the film after watering first will cause the medicament gas to escape and reduce the killing effect. After reading the above methods, now I know how to properly cover the film after the stagnation of the pharmacy? I hope this article can help our vegetable farmers and friends, want to know more about agricultural technology, welcome to pay attention to Hui Nong network!
