Abstract: The temperature and winter-proofing effects of bagging the bunch of banana (Musa acuminata cr. Dwarf Davendish) with nattier blue polyethylene film bag as well as the growth and development of fruits and yield were studied. The results showed that after bagging banana bunch in winter, the temperature inside the bag was increased by 1-5℃, therefore the fruits were effectivsly prevented from chilling injury.The growth and development of fruits were also promoted,and the yield of banana was increased by 8-16%. This method is effective to prevent banana fruits from chilling injury and increase the yield in wintering season.

摘要： 冬季香蕉果穗用兰色聚乙烯薄膜套袋之后,可提高袋内温度1~5℃,果实低温伤害卑只有1%左右,而未经套袋的达23%~35%,果指长度和径围增加率分别达12%和9%左右,果实产量比对照增加8%~16%。试验结果表明,兰色聚乙烯薄膜套袋是越冬期间香蕉防寒保果和增产的一项有效措施。
