What are the main protective effects of greenhouse film?

Greenhouse film I think many farmers and friends must be very clear, especially for users of greenhouse operations, the importance of greenhouse film is self-evident, so what are the main protective effects of greenhouse film? The following is a detailed introduction to the professionals of Luji Plastic Industry, let's learn together. 1. Greenhouse film can be used as soil fungicide. Plant protection films have inhibitory resistance and defense against different fungi, while powdery mildew, fungi and other woods can inhibit certain plant diseases. 2. Greenhouse film can improve soil, soil and organic acids stimulate the surrounding microbiological useful plant root system to make it active, thereby accelerating the decomposition of organic matter, including microbiological, resin, wax, tannin and lignin still exist , etc. to increase soil organic matter. 3. The greenhouse film has strong penetration and adhesion, which is a long-term fertilizer nutrient for the attached crops. In order to promote the 2 to 3 days of crop maturation, the yield is increased, and the effect of prolonged storage and transportation of vegetables is also evident. 4. Greenhouse film can improve the disease resistance of crops. It has a strong inhibitory effect on nematodes and other common pests and diseases, can balance the microbial flora, reduce pests and diseases, and has a strong preventive effect on root rot, anthracnose, rot and other branches. 5. Greenhouse film can promote the growth of crop roots. The protective film of plant phenolic compounds can affect the oxidase activity of the plant growth hormone in the body, and the plant protective film can promote the activity of soil actinomycetes (that is, the production of secretion cytokinin), which plays an important role in promoting the development of root crops. 6. The plant protection film in the greenhouse contains acetic acid, methanol and phenol, which can improve the penetration and application of pesticides, so as to exert better effects and reduce the use of pesticides. It should be noted that it is not mixed with alkaline pesticides.
