| 摘 要： | 为提高四川桤木无性系采穗圃穗务产量，对其无性系进行了修枝与施肥试验，试验表明：在无性系定杆150cm高时，将其抽发的侧枝进行短截修剪，修剪强度以轻、中短截效果最佳，可显著提高无性系穗条产量，在无性系定杆120cm高时，施用氮肥可显著提高无性系穗条产量?

| Abstract: | In order to increase the output of the clonic tassels of Alnus cremastogyne Burk, pruning and fertilization methods were tested on various clones. The results showed that using the follwing methods can increase the output of cloned tassels: Short pruning on lateral branches and using light and low cutting intensity when the clone stick is 150?cm height, and fetrilizing with the N when the clone stick is 120?cm heilght. |
