| 摘 要： | 以5～6年生高接青树为试材,研究了不同留果密度对青果实生长发育的影响。试验结果表明:每10cm或15cm留1个果的处理效果较好,其果实纵、横径的发育速度和单果重均极显著地高于对照和每5cm留1个果的处理。10cm和15cm的处理间对照和5cm之间的果实纵横径及单果重无显著差异。叶果比以20～23∶1(每果占有面积约300cm2左右)为宜。

Effect of Fruit Thinning on Top Grafting Plum Trees in Area of Tianjin |
| |
| Abstract: | In the experiment ,effect of three treatments consisting of5cm,10cm and15cm fruit set intervals on plum tree were investigated.The fruits of ck were thinned as many as usual.The results showed that fruits of both10cm and15cm interval treatments were bigger than that of ck and5cm treatment in longwise,crosswise and fruit weight.However there was no significant difference be-tween10cm and15cm treatments.The optimum leaf/fruit ratio was20～23∶1.The dimension of leaf per fruit was300cm 2 . |
