多功能转光塑料薄膜 (以下称多功能转光膜 )是一种具有长寿、无滴 ,并能把日光中的部分紫外线紫光转换成红光功能的新型塑料薄膜。通过在蔬菜、瓜果、花卉等 7种作物上的对比试验 ,结果证明 ,与普通无滴膜相比 ,多功能转光膜可以提高光温效应 ,促进作物营养生长 ,提早生育期 ,增加产量 10 .5 %左右 ,还能改善农产品品质 ,如提高维生素 C和糖的含量 ,由于增产的主要是早期产量 ,因此经济效益高 Multifunctional light transfer plastic film (hereinafter referred to as multifunctional light transfer film) is a kind of long life, no drip, and can part of the sun’s ultraviolet violet light into a new type of plastic film function. The results of contrast tests on seven crops, including vegetables, fruits and flowers, showed that compared with common non-dripping film, the multifunctional light-transmissive film can enhance the effects of light and temperature, promote the vegetative growth of crops, promote the growth period and increase the yield About 10 .5%, but also improve the quality of agricultural products, such as improving the content of vitamin C and sugar, due to the increase of production is mainly the early production, so high economic efficiency
