在夏秋季气温转高的地方,贮藏好中晚苹果品种的关键,首先是降低贮藏环境的温度。要降低贮藏环境的温度,可以在高大建筑物的背荫处,挖作地沟,借夜间冷空气的下沉,来降低沟温和果温。由于挖沟位置,与传统的背风、向阳处不同,因此,这种地沟又叫“改良地沟”。为了提高改良地沟的贮藏效果,可以在果筐内套以0.07毫米厚的聚乙烯薄袋,或在0.1毫
In summer and autumn where the temperature goes up, the key to storing late apple varieties, the first is to reduce the temperature of the storage environment. To reduce the temperature of the storage environment, dug ditches can be dug at the backs of tall buildings to reduce the temperature of the ditch and the fruit temperature by sinking cold air at night. Due to the trenching position, unlike the traditional leeward and sunny positions, this ditch is also called “improved ditch.” In order to improve the storage effect of the improved ditch, a 0.07 mm thick polyethylene sachet can be placed in the basket or a 0.1 mm
