果品在包装运输贮藏过程中容易发生腐烂,不少单位由于防腐保鲜工作没有搞好,造成较大的损失。例如某省某果品公司,有一年从农场购买了三、四千担蕉柑贮藏为春节供应用,贮藏两个月烂耗率达40%以上。一九七二年某进出口分公司从农场运一批夏橙到香港,从采果到出售前后只有15天,烂耗率达60%。一九七六年我省某县果品公司贮藏的温州蜜柑腐烂率达40%,一人一天拾烂的柑皮可卖几拾元钱;汽车开到柑桔场,整个车轮都陷在烂果堆里。柑桔算是较耐藏的果品,但柑桔贮藏烂耗率在14%,就算是先进单位了。在正常的年景,水果增产15%不太容易,增产40%就更困难了,上面的例子却把增产部分轻易地腐烂损失了,农民一年辛勤劳动换来的增产结果全落空了。这不能不引起人们应有注意与重视。 Fruit in the process of packaging and transportation of storage prone to decay, many units due to preservative preservation work did not do a good job, resulting in greater losses. For example, a fruit company in a province, one year from the farm to buy three or four thousand pairs of banana storage for the Spring Festival for storage, storage two months burn rate of more than 40%. In 1972, an import-export branch transported a batch of summer orange from the farm to Hong Kong. From picking fruit to selling it, it only took 15 days and the rate of rotting was 60%. In 1976, a county in our province, the company stored 40% of the Wenzhou orange juice decay, citrus peel picking up a day can pick up a few dollars; car to the citrus field, the entire wheel is stuck in the rotten fruit pile in. Citrus is considered a more durable fruit, but the citrus storage rate is 14%, even the advanced unit. In normal years, a 15% increase in fruit production is not easy and a 40% increase in production is even more difficult. However, the above examples have easily lost the decayed part of the increase in output, and the result of hard work in a year has been totally lost. This can not but arouse people’s attention and attention.
