“美丽”李果实品质优良、外观艳丽、果个大、丰产稳产，但在泰安司家庄园艺场表现为座果率低、产量少，９年生树平均株产不足６ｋｇ。通过调查，“美丽”李座果率低的主要原因是由于自然授粉率低，花期喷５０ｍｇ·Ｌ－１赤霉素、０５％尿素对提高“美丽”李的座果率有良好效果。此外，贮藏营养多的粗壮枝、花簇状果枝座果率也相应提高，“美丽”李落果主要在生理落果期发生。
“Beautiful” plum is of good quality and gorgeous appearance with a large fruit size and a stable yield. However, the fruit yield is low and the yield is low in the Taiyuan Sijiahuang Art Fair. The average yield of 9-year-old trees is less than 6kg. According to the survey, the main reason for the low rate of “beautiful” plum fruit is that the natural pollination rate is low. The effect of spraying 50 mg · L-1 gibberellin and 0.5% urea on the fruit setting rate of “beautiful” plum is good . In addition, sturdy branches and bouquets of fruit trees with a large number of stored nutrients also increased correspondingly, and “beautiful” plum fruits occurred mainly in the physiological deciduous period.
