MULCHING FILM WITH STERILZATION AND INSECTICIDAL EFFECT AND METHOD OF PRODUCING THEREOF

摘要

The present invention relates to a mulching film having a sterilizing and insecticidal effect and a method for producing the mulching film and a biodegradable polymer having a polymerization degree of 1500 to 2000, a degree of saponification of 95 to 99.8% and a number average molecular weight of 50,000 to 80,000. Plasticizers; A crosslinking agent; Cellulose based resin; And a physiologically active substance having a sterilization and insecticidal effect. In comparison with the conventional polyethylene mulching film, the strength and elongation of the phosphorus are increased, and more than 90% is decomposed within 1 year after use. Can be adjusted. In addition, no separate collection is necessary, and pathogens derived from the soil can be blocked to prevent pests and diseases.
