采收后的苹果,仍然是一个活的、有生命的有机体,它仍然要进行呼吸作用。即吸收空气中的 O_2,把果实中的有机物质分解成 CO_2和水。抑制果实的呼吸强度,延长其生命过程,可使果实得以长期贮藏。应用以上原理,用薄膜塑料袋密封苹果,是一种简便易行,效果较好的贮藏方法。这种方法,一般果窖和农村社队的土窖,甚至家庭贮果都可应用。苹果在密闭的小袋里进行呼吸,小袋里 O_2的浓度不断降低,CO_2的浓度逐渐增加,呼吸强度被抑制,延长了贮存时间,损耗也相应减少。从我场近几年的试验看出,用小包装法, The harvested apple, still a living, living organism, still has to breathe. That is absorbed in the air O_2, the organic matter in the fruit is decomposed into CO_2 and water. Inhibit the fruit’s respiratory intensity, to extend its life process, the fruit can be long-term storage. Application of the above principle, with a plastic film sealed apple, is a simple and easy, better storage method. This method, the general cellar and the cellars of rural communes and even household storage of fruit can be applied. Apple in a closed sachet to breathe, the concentration of O_2 in the pouch continued to decline, the concentration of CO_2 gradually increased, respiratory intensity was suppressed, extending the storage time, the loss is also reduced accordingly. From our field in recent years the test shows that with a small package method,
