| 摘 要： | 应用4000倍和5000倍的BR－120、800倍和1000倍的PP－2003于盛花期和幼果喷施桃树两次，座果率显著增加，分别比对照提高51．52％、36.49％和33．11％、48.82％;枝梢长度和粗度显著或极显著增加，分别比对照增长40．96％、24、40％和20．14％、51．24％；叶片叶绿素含量和净光合速率显著或极显著增加，其中叶绿素含量与净光合速率呈直线相关，相关系数达0．9882，达极显著水平。生产上可用于提高桃树座果率和促进枝梢的生长。

| Abstract: | In this experiment, 400 and 5000 - time BR, 800 and 1000 - time PP - 2003 solutions were spraye'd upon peach trees in the full - bloom stage and young -fruit stage, and the percentages of fertile fruit were significantly increased by 51. 52% and 36. 49 %, 33. 11% and 48. 82%: the lengths and diameters of branches were significantly or mostly significanlly raised by 40. 96% and 24.40%, 20. 4%and 51.24%, respectively, the content of chlorophyll and net photo synthetic rates in the leaves were also significantly or highly significantly increased, and the content of chlorophyll was straightly correlation with the net photosynthetic rates. The correlation coefficient was up to 0. 9882,which attained montly significant leveos. Therefore,BR - 120 and PP - 2003 could be used for improving fruit setting and enhancing branch growth in the production. |
