聚乙烯多功效大棚膜的研制和对蔬菜的增产效果及其机理探讨

The Studies on the Manufacture of the Multi-Functional Polyethylene Green-house Film and the Effect and Mechanism of Incresing Yield on Vegetables

三年来,经过多点试验,结果表明:新光多功效大棚膜具有明显增温、隔热、提高光照度、减少棚顶的水雾水滴、增加色光和减少近紫外光作用,对蔬菜的增产效果明显优于普通大棚膜及同类产品。在应用试验的同时,对其增产机理也作了探讨。

Having tested on many spots in three years,the results showed thatXinguang multi-functional green-house film has an obvious effect on increasingtemperature,heat-insulation,elevating illuminance,decreasing water fog anddrops of the top of green house,raising eolour light and reducing the effect ofnear-UV light.The effect of increasing yield on vegetables is superior to theconventional agricultural film and other multi-functional film.The mechanismof increasing yield on vegetables had been studied as well.
