‘金红’苹果徒长枝的利用研究

Study on the Utilization of 'Jinhong' Apple Water Branch

设计‘金红’苹果徒长枝拉枝,短截1/4、1/3、1/2(修剪长度/原枝条长度)4个处理,比较不同处理对花丛数及枝条数的影响,以便根据不同利用目的找出最好的修剪方法。试验结果表明,短截1/4,花丛数、中枝数、短枝数最多;拉枝的花丛数多,但成枝力差;短截1/3的成枝力强,短枝也多。生产中应根据树势强弱综合运用适度短截和拉枝。

Set the ＇Jinhong＇ apple water branch-bending,short cut 1/4,1/3,1/2（pruning length/length of the original branch）,a total of 4 treatment,effects of different treatments on the number of flowers and the number of branches,in order to find out the best pruning method according to different use purpose. Experimental results show that,short cut 1/4,the number of flowers,the number of branches,the number of short branches up to;the number of branch flowers,but the principal stress difference;short cut 1/3 into strong branches,short branches are also more. According to the growth of the comprehensive strength of using appropriate short cut and branch production.
