“果实整形素”是能显著改良苹果外观品质的植物生长调节剂。通过多点对红富士、新红星和秦冠苹果的试验结果来看，盛花期喷一次５００倍液的果实整形素，可显著地增长苹果果实的纵径，从而能明显地提高采收时果实的果形指数。试验表明，用果实整形素处理较喷清水的对照果实采收期一般可提高果形指数０．０５—０．１２，同时还能增加果实单果重和果树产量。 “Fruit plastic” is a plant growth regulator that can significantly improve the appearance of apples. According to the experimental results of multi-spot red Fuji, new red star and Qin crown apple, when sprayed with 500 times of fructan in full flowering stage, the longitudinal diameter of apple fruit can be significantly increased, which can obviously improve the fruit harvest Fruit shape index. The results showed that the fruit shape index 0.05-0.12 can be increased by the treatment of fruiting plastic compared with sprayed water, and the fruiting body fruit weight and fruit yield can be increased at the same time.
