摘　　要：试验选用20%华碘抗胁迫生态膜,进行了乔化免套袋苹果应用不同浓度华碘抗胁迫生态膜病虫害防控效果对比试验。结果表明,20%华碘抗胁迫生态膜对苹果果面保护及果面着色与光能膜差别不大,但其病虫害防控力强,增强苹果树对病虫害的抗逆性、促进生长、提高苹果果实内在品质等作用表现得更加显著。但浓度过高时,在一定程度上影响了苹果叶片的光合作用和苹果果实外观品质,会使苹果失去商品性。In the experiment,20% Hua-iodine anti-stress ecological membranes were selected,and the comparative test of the disease and pest prevention effect of apply to different concentrations of Hua-iodine anti-stress ecological membranes were carried out in Qiaohua non-baggled apples.The results showed that the 20% Hua-iodine anti-stress ecological membranes had little difference on apple fruit surface protection,fruit surface coloring and light energy membranes,moreover it had strong of disease and pest prevention ability,and had more significant effects on enhance of apple tree's resistance to disease and pest,promoting growth and improved the internal quality of apple fruit.However,when the concentration is too high,it will affect the photosynthesis of apple leaves and apple fruit appearance quality to a certain extent,and will make apple lose its commodity property.
