紫光膜在设施园艺生产上应用效果的研究

Studies on the application effect of purple plastic film on the establishment production of gardening

在设施园艺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、保温性以及对蔬菜、果树的生长发育的影响等进行研究,结果表明紫光膜具有透光 率高、保温性能好、耐用、防尘、防雾效果好且能促进蔬菜、果树生长发育,提早开花结实,提高产量、 产值,提高蔬菜和果品质量等作用。

It is an important way to realize energy saving and highly effective production to use transparent cover which is high in photo rate, good in heat preservation, durable and good in dust control and fog protection in the establishment production of gardening. The author did some research on light permeability, heat preservation and the effect on the growth of vegetables and fruit trees by using pairing method in 1998～2000. The result shows the purple plastic film is not only high in photo rate, good in heat preservation, durable and good in dust control and fog protection but also it can promote the growth of vegetables and fruit trees, make vegetables and fruit trees blossom and bear fruit early, in crease output and output value and improve the quality of fruit.
