摘　　要：在温室果树生产上选用透光率高、保温性能好、耐用、防尘、防雾效果好的透明覆盖物,是实现节能、高效生产的重要途径。作者于2002—2004年在辽宁农业职业技术学院试验地,利用对比法对EVA薄膜的透光性、保温性以及对果树的生长发育的影响等进行研究,结果表明EVA薄膜具有透光率高、保温性能好、耐用、防尘、防雾效果好且能促进果树生长发育,提早开花结实,提高产量、产值,提高果品质量等作用。It is an important way to realize energy saving and efficient production by using the kind of transparent cover with higher transmittancy and better heat preservation properties, which is durable and good at the control of dust and fog for the protected fruit production in sunlight greenhouse.The light transmittancy,heat preservation properties and the effect of EVA thin film on the growth of protected fruit trees were researched by contrasting method in 2003-2004.The results showed that the EVA thin film not only was high in light transmittancy,good in heat preservation,durable and good at the control of dust and fog,but also could promote the growth of fruit trees,make that blossoming and fruiting early,in crease yield and output value and improved the quality of fruit.
