1. Greenhouse structures must be designed properly to ensure the film angle reaches above 30°, allowing water droplets to flow down the film naturally.

2. Prohibit the use of sulfur fumigation and闷棚 methods, as well as the application of strong acids and highly toxic pesticides to avoid affecting the lifespan of the greenhouse film and the fogging and dripping period.

3. Avoid direct contact and friction between the greenhouse film and pointed objects such as wires, bamboo poles, etc., to prevent unnecessary damage to the film.

4. The agricultural film must be tightened and flattened to ensure unobstructed drip flow.

5. Prohibit the use of tire rubber, drip irrigation belt snake tubes, and other materials for wrapping greenhouse frames to prevent rust on iron pipes and PVC pipes, and avoid direct contact with greenhouse film to prevent premature damage to the film.
