| |
| Abstract: | The shoots shriveling on young apple trees during winter is universal in Fangshan county of Shanxi province. In this experiment, the shoots shriveling was effectively prevented and decreased by spraying 5% JBXS and Jing 2B(30×) on young Starkrimson and Goldspur apple trees. The index of the shoots shriveling was reduced by 10.83%～15.15% by spraying 5% JBXS,and 7.57%～13.01% by spraying Jing 2B(30×),respectively. |
