苹果的采收期适宜与否,对果品的产量、品质、耐贮性和经济收入等都有着显著的影晌。据研究,苹果果实在充分成熟前,一般每天可增重1-1.5％。早采收半个月的红玉,比适期采收的,减产16.6％。但若采收过晚,特别是果实在树上已通过呼吸跃变期后,耐贮性就会大大降低。因此,适期采收,也是苹果生产中的一项不可忽视的重要措施。苹果的适宜采收期,要根据不同的品种、特 Appropriate harvest time of the apple or not, the fruit yield, quality, storage and economic income have a significant impact. According to the study, before the fruit of apple is fully ripe, the daily gain of 1-1.5% can generally be increased. As early harvest half a month of red jade, than the harvest, cut 16.6%. However, if the harvest is too late, especially in the tree has passed the respiratory transition period, the storage will be greatly reduced. Therefore, the appropriate harvest, but also an important apple production can not be ignored. Appropriate harvest of apples, according to different varieties, especially
