不同修剪方法对猕猴桃新蔓发育和产量的影响

采用不同修剪方法对猕猴桃新蔓发育和产量的影响进行了研究.结果表明:通过合理冬季修剪能够显著提高成蔓率、开花量、结果量、坐果率、单株产量和平均单果重,其中,以剪留春蔓段1/4处理的效果最好,其次是剪留春蔓段1/5处理的效果,最差是剪留春蔓段1/3处理的效果;通过合理夏季修剪能够显著提高开花蔓数量、开花量、结果量、坐果率、单果重、含糖量和小区产量,其中,以留5～6片叶处理的效果最好,其次是留7～8片叶的处理和留3～4片叶的处理,而效果最差的是留9～10片叶的处理.

Effects of Different Pruning Methods on New Vine Development and Yield of Chiese Gooseberry

Guichang,a Chinese gooseberry variety,was tested to study the effect of different pruning methods on its new vine development and yield.The results showed that the new vine rate,flowering quantity,fruit-setting rate,yield per plant and average single fruit weight could be increased significantly by rational pruning in winter and the effect order was keeping 1/4 spring vine section,keeping 1/5 spring vine section and keeping 1/3 spring vine section,and that the number of vines with flowering,flowering quantity,fruit setting quantity,fruit setting rate,single fruit weight,sugar content and plot yield could be increased by the rational pruning in summer and the effect order was keeping 5 to 6 leavies,keeping 7 to 8 leavies,keeping 3 to 4 leavies and keeping 9 to 10 leavies.
