多功能转光塑料薄膜应用效应研究

Effect of Multifunctional Plastic Film Transfering Violet Ray to Red Light (VTR) Applied in Field

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 。

The multifunctional plastic film transfering Violet ray to Red light(VTR) as the new plastic film has long life and non drop character. It can transfer violet ray of sunlight to red ray. Contrasted to general non drop film, the result of field experiments on seven crops of vegetables, fruits, and flowers indicated that VTR film can increase luminousness and temperature condition in plastic tunnel, improve vegetative growth, advance development of crop, increase yield by 10.5% or so. Furthermore, It can promote the quality of agricultural products such as increasing the saccharine content. The increased yield mostly happened at early stage, so there were certain economic benefits for farmers.
