How to store agricultural film

Plastic film mulching technology is widely used in rural areas. In order to improve economic benefits, farmers change the use of plastic film once a year to two or more times a year. The five methods of agricultural mulch collection are as follows: 1. Dry bag storage method Wash and fold the mulch that has covered crops, put it in a plastic bag, tie the bag tightly, and put it in a humid and cool place, keep away from heat sources, prevent Sunlight deterioration, this method can generally be stored for 2 years. 2. Straw core rolling method: Roll the washed and sun-dried film into a tube shape, and add straw as the core in the middle for ventilation. When rolling the film, it is best to add a little talcum powder to avoid sticking, and then put the rolled film in the warehouse, etc., usually move less, and pay attention to preventing high temperature, high humidity and rodent damage. 3. Water storage method: Wash the covered mulch, then roll it into bundles or fold it neatly, put it in a tank or pool, put a heavy object on the mulch, pour in clean water to soak the mulch, and then cover it for shade. During storage, the pool and tank cannot be dehydrated. This method is preserved, and the service life can reach 5—6 years. 4. Soil storage method Wash the covered mulch, fold it or roll it into a bundle, pack it in a plastic bag, dig a soil hole 80 cm deep, put the mulch in it, and cover it with 30 cm thick soil. The preservation effect is the same as the water preservation method. 5. The method of cellar storage Put the cleaned mulch film, then fold it with water droplets, put it into a plastic bag, tie the bag mouth tightly with a string, and put it in the cellar. This method is better than the dry bag storage method.
