【摘要】 研究了地面铺反光膜及不同果袋、不同解袋时间等对果实品质的影响。结果表明,铺设反光膜可以全面提高果实品质,减少重庆光照不足和套袋对油桃果实发育的不利影响;适当延迟解袋时间,从常规的采前7-10d延迟到采前3-5d,最迟不超过7d,在重庆气候条件下,可以保证较好的外观品质,获得较好的防病虫防裂果效果;外褐内红双层纸袋处理的果实果面光洁度、色泽均匀度、防病虫和裂果效果明显优于牛皮纸单层袋、褐色单层纸袋处理。更多还原

【Abstract】 Due to the problems of poor fruit quality, disease and pest fruit rate sharply increasing after bag removed as well as paper bag broken by rains etc., experiments of laying light reflecting film, choice of date of removing the bag and kind of bag used were carried out in a nectarine orchard for studying their effects on the fruit quality. The results showed that laying light-reflecting film on the ground could improve fruit quality and decrease the bad effects of weak light in Chongqing area. Removing bag 3 to 5 days,no more than 7 days before harvest could get fruit with ideal appearance and suffer from less pests and diseases. Nectarine fruit bagged with double-layer paper bag (with red inner layer and brown outer one) could make the fruit skin smoother, coloration brighter, diseases and pests fewer and as well as craking fruit fewer.更多还原
