摘　　要：为柑橘无公害生产提供参考,选择15年树龄纽荷尔脐橙进行试验,研究乳白色单层纸袋和外黄内黑双层纸袋进行果实套袋对纽荷尔脐橙果面绿斑病和果实品质的影响。结果表明:纽荷尔脐橙果实套乳白色单层纸袋可提高其果皮亮度、黄色值和红色值,明显改善果实外观品质;套外黄内黑双层纸袋果实的着色较差,单果重、果形指数与未套袋果实差异不显著;套袋果实VC含量均比未套袋果实高,且差异达显著水平,但可溶性固形物、总糖和可滴定酸含量与未套袋果实差异不显著。套袋能有效控制果面绿斑病发生,且乳白色单层纸袋除能有效控制果面病虫害外,还可改善果实外观品质,增加果实商品价值,实现无公害生产。乳白色单层纸袋优于外黄内黑双层纸袋的套袋效果。The effects of two bagging patterns(the ivory single-layer paper bag and the outside yellow and inside black double layer paper bag)on green spot disease and fruit quality of oranges on Newhall Navel Orange trees with15years old are studied to provide a reference for pollution free production of citrus.Results:The ivory single layer paper bagging pattern can increase peel brightness,yellowing and redness of Newhall Navel Oranges and improve fruit appearance quality obviously.The outside yellow and inside black double-layer paper bagging pattern decreases fruit color and its single fruit weight and fruit shape index are no obvious difference with CK(no bagging pattern).The bagging can effectively control occurrence of green spot disease on fruits.The ivory single-layer paper bagging pattern not only controls fruit pest and disease damage effectively but also improves fruit appearance quality and increases fruit commercial value,which indicates that pollution free production of citrus can be realized.In conclusion,the ivory single-layer paper bagging pattern is better than the outside yellow and inside black double-layer paper bagging pattern in production of Newhall Navel Orange.
