农用薄膜正从单一的保温增产功能向保温、遮光、无滴、防病、除草、科学采光、增产等功效方向发展。一批新型的农膜,如彩色膜、降解膜、无滴膜应运而生。 彩色膜是根据光学原理而生产的。科学研究证明,不同的光对作物的作用不同,如水稻、玉米在红、橙光的照射下,生产发育加快,在红光下生长的甜瓜可提前 Agricultural film from a single thermal insulation production function to the insulation, shading, no drip, disease prevention, weeding, scientific lighting, production and other efficiency direction. A number of new types of agricultural film, such as color film, film degradation, no drip film came into being. Color film is based on the principle of optics and production. Scientific research shows that different light has different effects on crops, such as rice and maize under the irradiation of red and orange light, the development of production is accelerated, and the melon growing under the red light can advance
