塑料薄膜袋贮藏有生命活动的果实,受到薄膜透气性能的很大影响,而不同种类的果实要求薄膜对CO_2、O_2的透性不一致,即使同一种类的果实由于品种不同,要求薄膜对CO_2、O_2的透性也不相同,同时薄膜透气性能还受到气候因素的影响。因此,各省区经贮试筛选的薄膜不能通用。为了获得一种或数种适合我省常温库贮藏苹果用的薄膜,所以我们于1975～79年对30多种型号的薄膜进行
Plastic film bags store the fruits of life activities, which are greatly influenced by the breathability of the films. Different kinds of fruits require that the films have inconsistent permeability to CO_2 and O_2. Even though the same type of fruits are different in variety, Permeability is not the same, while the permeability of the film is also affected by climate factors. Therefore, the provinces selected by the test film can not be used universally. In order to obtain one or more films suitable for storage of apple at room temperature in our province, we conducted over 30 types of films from 1975 to 1979
