连续３年对１～４年生叶用银杏进行了整形修剪研究，发现１～２年生实生银杏侧芽发育瘦弱，顶端优势明显；生长季节内除顶芽萌发抽枝外，侧芽难以萌发抽枝；３～４年以后侧芽发育较为饱满，抽生侧枝数量逐渐增加。休眠期内破除１～２年生银杏顶芽，能有效地刺激其侧芽萌发，增加枝梢数量和叶片产量；３～４年生时休眠期内破除顶芽或轻度短截，再加上生长季节摘心，能明显增加分枝数量，控制株高过度生长，增加群体叶片产量，便于各项经营管理措施的实施。
For three consecutive years, the leaf pruning of 1 to 4 years old leaves was studied. It was found that the gingko lateral buds of 1 to 2 years old were thinly developed and the apical dominance was obvious. Except for the top buds during the growing season, it was difficult for the lateral buds to sprout; 3 After 4 years, the development of lateral buds is more full, and the number of parascending branches gradually increases. Dormancy 1 to 2 years to get rid of ginkgo end buds, can effectively stimulate the germination of its lateral buds to increase the number of shoots and leaf yield; 3 to 4 years old during dormancy to get rid of top buds or mild stub, plus the growing season Topping, can significantly increase the number of branches, overgrowth of plant height, increase population leaf yield, facilitate the implementation of various management measures.
