| 摘 要： | 为改进桑树夏伐技术,促进桑树生长,对湖桑32、选792和新一之濑3个桑品种夏伐后残留叶片的生理作用进行了研究,结果表明:残留叶片的叶绿素含量和光合能力在夏伐后迅速提高,伐后第5天达到最大值,以后缓慢下降;残留叶还可以减少伤流量、缩短伤流时间;保留基部叶片平均可使每枝多发1芽且新芽生长速度较不留叶明显提高;对残留叶片喷施尿素,效果更显著。

| Abstract: | Through testing the physiological effect of the remained leaves, the results showed that the content of chlorophyll and the photosynthetic rate of the remained leaves increased rapidly, and reached the climax at the fifth day after summer cutting and then decreased slowly. The remained leaves can reduce not only the quantity of the bleeding but also the time of bleeding, and improve the number and growth vigor of the sprouted branches. Spraying CO(NH2)2 to the remained leaves,the effect will get clearer. |
