Several measures to reuse PO agricultural film

Reducing the cost of agricultural production is conducive to the development of agriculture. PO agricultural film can be reused if used properly. Here are several measures to achieve PO agricultural film reuse:
1. Cover the PO agricultural film directly on the surface of the sown or cultivated crops, and take back the mulch film after the temperature rises, store it for reuse. This kind of mulch is temporary covering, which is short in time and has little damage to the mulch. Used in spring and autumn, it can keep crops warm and protect from wind and rain.
2. One mulch, multiple stubble continuous planting: spring crops are covered with PO agricultural film, which remains intact after summer harvest, and continues to be used in autumn, or covered in autumn and used in winter. Such as spring cucumbers, beans and other covered agricultural film, autumn can be used to grow Chinese cabbage, kale, etc. In this way, the same PO agricultural film can be used in spring and autumn, which can increase the temperature and accumulated temperature and reduce investment.
3. Make a small arch shed first, and then make mulch film: first use the plastic film for the small arch shed, and then use the ground film after falling, which can be used for the cultivation of early maturing crops in spring. The bamboo pieces or branches used for the arch should be smooth and free of sharp corners to avoid scratching the film.
4. Old membrane sleeve new film, double film cover: after early spring crop sowing, cover the new film on the surface, and then make the old PO film into a small arch shed to cover the outside of the new film; Or after the crop seedlings are planted, use the new membrane hole to make the mulch film, and make the outside as a small arch shed to cover the old film, which can improve the moisture of the soil, promote seed germination and the growth of seedlings, so that the old film can be reused, and the stubble under the new film will continue to be used.
