摘　　要：在黑龙江省苇河林业局冲河苗圃试验地通过对不同修枝强度下的茶条槭S1-0鲜叶干叶产量及分枝数的调查与分析,结果表明:修枝强度对茶条槭苗高、地径生长无显著差异,对叶产量及分枝数有显著影响.剪梢强度以全株长1/3～1/2对提高其鲜叶、干叶产量效果最佳,分枝数也最多.Production of fresh and dried leaves or numbers of divarication of S 1-0 seedlings of Acer ginnald under different intensity of pruning were investigated and analyzed.Results showed that intensity of pruning on height of seedlings and ground diameter had no significant differences, but had sifnificant differences on production of leaves and numbers of divarication.Truncated intensity made up 1/3~1/2 of the total plant.The effect of raising production of fresh and dried leaves was the best,the numbers of divarication were the most.
