紫光膜在保护地果树生产上应用效果的研究

Studies on the application effect of purple plastic film on the protective ground production of fruit trees

在保护地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1998～2000年在辽宁农业职业技术学院试验地,利用对比法对紫光膜的透光性、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,紫光膜透光率高,保温性能好,耐用,防尘,防雾效果好,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。

It is an important way to realize energy saving and high economic effect production by using transparen cover which is high in transmittancy,good in heat preservation,durable and good in dust and fog control in the protective ground production of fruit trees． The author did some research on light transmittancy,heat preservation and the effect on the growth of fruit trees of purple plastic film using pairing method in 1998－2000．Results showed that the purple plastic film not only was high in transmittancy,good in heat preservation,durable and good in dust and fog control but also could promote the growth of fruit trees,make fruit trees blossom and bear fruit early,in crease yield and output value and improve the quality of fruit．
