我省年产苹果25亿斤左右,一般采用常温库或传统的沟藏及常温下小包装贮藏。由于苹果采收和入贮初期温度偏高,传染病害和生理病害发生严重,每年贮藏损失达5—6亿斤,其中近半数是红星、金帅等中熟品种。贮后中熟品种的好果率常降至50%以下。常温下贮藏的苹果失重达20—60%。我们自1980年起查阅了省内主要苹果产区中熟品种成熟期的气温资料,分析了烟台地区晚熟品种的沟藏经验,研究提出了改良地沟加塑料小包装贮藏苹
Our province produces about 2.5 billion jins of apples per year, generally using normal temperature storage or traditional ditch storage and storage at ordinary temperature. Due to the high initial temperature of apple harvesting and storage, infectious diseases and physiological diseases are serious, and the annual loss of storage reaches 5-6 billion jins, of which nearly half are middle-maturing varieties such as Red Star and Jinshuai. After storage medium-maturing varieties of good fruit often fall below 50%. Apples stored at room temperature lose weight up to 20-60%. Since 1980, we have reviewed the temperature data of ripening maturity of major apple producing areas in the province, analyzed the experience of furrowing of late maturing varieties in Yantai,
