In recent years, plastic film mulching technology has been widely used in rural areas. In order to increase economic efficiency, peasants use one time for two years or more for one year. Therefore, how to properly preserve the plastic film, prevent aging, and avoid deterioration has become a practical problem that farmers must solve. Here are five methods for the collection of agricultural plastic film as follows: 1 Dry bag method This refers to the method of bagging and preservation of the plastic film under natural conditions. Cover the mulching film of the crop, wash it well, pack it in a plastic bag, tie it tightly, place it in a moist, cool place, and do not approach the heat source. Prevent sun exposure. This method can generally save 2 years. 2 The grass core reeling method rolls the washed and dried film into a tube shape, and straw is used as a core for air ventilation. It is best to add some talcum powder to prevent sticking when rolling the film. Then place the rolled film on the cabinet, etc., and usually move less, and pay attention to high temperature, high humidity and rat damage. 3 The water storage method will cover the mulch, wash the soil, and then roll up into bundles or stacks neatly and put them into the tanks and pools. Press heavy objects on the mulch, pour the clean water into the mulching film, and then cover the shade. During storage, the tank and tank must not be dehydrated. This method saves, life can reach 5 - 6 years. 4 The adobe will cover the mulch, wash the soil, fold it up or roll it into bales, pack it in plastic bags, dig an earth pit 80 centimeters deep, put the mulch into the country, and cover 30 centimeters of soil. Save the same effect as water. 5 The mulch film to be washed by the kiln will be plucked with water droplets and put into a plastic bag. Use a string to tie the bag and put it into the cellar. This method is better than the dry bag method. China Agricultural Network Editor
