| 摘 要： | 连续2 a对红富士苹果密闭树改形修剪进行了研究.结果表明,改形修剪能提高树冠中下部的光照强度,促使树冠光照分布均匀;改形修剪树的百叶重比不改形增加了29.0,百叶厚增加了32.9,叶子干鲜比增加了10.5,总叶绿素含量增加了35.2,单果重增加了31.9,着色指数提高了16.6,可溶性固形物含量提高了12.2.

| Abstract: | Continuously 2 years study on modifying apple tree crowns of shade apple tree indicated that the relative light intensity on lower part and middle part and the tree body illumination distribution could be improved. Weight of 100 leaves was increased by 29. 0% , thick of 100 leaves increased by 32. 9% , dry weight/fresh weight increased by 10. 5% , total chlorophyll increased by 35. 2% , weight per fruit increased 31. 9%, colour index increased increased by 16.6% , soluble solid increased by 16.6%. |
