四川晚熟柑桔品种的栽培,近年来发展较迅速,品种主要为血橙和夏橙。一股说来,晚熟品种甜橙耐藏性较好,采用常规保鲜技术(如2,4—D+多菌灵处理+薄膜包单果)即可有较好的贮藏效果。但是对于成熟和采收后正值春季升温或夏季高温的夏橙,如保鲜不力,损失很大。为此,我们对适于成熟中期采收的中熟种甜橙贮藏的2号保鲜防腐剂配方作了改进,并用于晚熟甜橙保鲜试验。1987年冬使用这种改进的2号保鲜防腐剂处理血橙,单果包薄膜贮藏70天,腐果率仅为
Cultivation of late-maturing citrus varieties in Sichuan has developed rapidly in recent years. The varieties are mainly blood orange and summer orange. In a word, late-maturing sweet orange varieties have good storage resistance, and the storage effect can be better by adopting the conventional fresh-keeping technology (such as 2,4-D + carbendazim treatment + film bagging). However, for mature and harvest positive summer or summer summer orange, such as poor preservation, the loss is great. Therefore, we improved the preservative formula No.2 for middle-aged sweet orange which is suitable for mid-ripe harvest, and applied it to the fresh-keeping orange fresh-keeping test. The winter of 1987 using this improved No. 2 preservative preservative blood orange, fruit pack film storage for 70 days, the rate of rotting fruit is only
