摘　　要：用不同夏季修剪方法对李生长发育的影响进行了研究 ,结果表明 :与传统的夏季不修剪树体相比较 ,短截春梢 1/ 3和摘心树体发育营养生长势得到缓和 ,春梢生长量小 ,促发二次梢发生量和生长量大 ,每个春梢能抽发≥ 30 cm的二次梢达 2 .2～ 2 .6个 ;同时 ,能提高次年树体开花量和坐果量。Research on the influence of different summer pruning methods on plum growth and development was carried out, The results were: compared to traditional non-pruning method,the treatment of cutting spring branch by one third and topping can bring fewer spring branches and stimulate growth of the secondary branches: 2.2 to 2.6 secondary branches (longer than 30 cm) emerged from per spring branch.
