苹果育果袋物理性状及其应用研究

采用２４种进口和国产苹果育果袋进行物理性状检测和田间试验，结果表明，进口袋外袋和内袋纸透气度、内袋纸表面吸水性、外袋不透明度、外袋纵向柔软度等技术指标多优于国产袋。因而，用进口袋所套果实外观品质普遍优于国产袋。为了促使国产袋的质量迅速赶上并超过进口袋，提出了苹果育果袋纸张物理性状参考控制值，建议尽快制定苹果育果袋的技术标准。

Study on the Physical Characters of the Bagging Bags for Apple Growing and Their Application

The Physical characters of 24 kinds of imported and native produced bags for bagging apple furit in the growing season were studied and applied in the field conditions. Results showed that the main technical indexes of imported bags, such as the ventilation quality of the outside and inside bag; the absorbent capacity of the inside bag;the transparency and the softness of the outside bag were mostly better than thore of the native bags; so the external appearance and the eating quality of the fruit bagged with imported bage were much better.For improving the native Produced bags the hag physical character indexes and the quality standard were suggested.
