通过连续3 a对中幼龄核桃进行修剪,并调查统计抽发枝梢情况、花枝率、果枝率以及单株结果量。结果表明,修剪后分枝长大于对照,2011年和2012年总的比对照增长8.43 cm;分枝粗小于对照,2011年和2012年总的比对照减少了0.35 cm;2011年和2012年的花枝率总的比对照增加了20.4%,果枝率总的增加了8.6%,单株结果树总的比对照增加了52个。对中幼龄核桃树进行适当程度的修剪,可增加抽枝量、促进开花结果和增加产量。
The young and middle aged walnuts were trimmed for 3 consecutive years, and the number of shoots, flowering rate, fruiting branch rate and yield per plant were investigated. The results showed that after pruning, the branch length was longer than that of the control, increasing by 8.43 cm in total in 2011 and 2012 than that of the control. The branch diameter was smaller than that of the control, decreasing by 0.35 cm in comparison with the control in 2011 and 2012. In 2011 and 2012 The rate of nodding increased 20.4% compared with the control, and the rate of fruiting branches increased by 8.6%. The total number of trees per plant increased by 52 compared with the control. A proper degree of pruning of young and middle-aged walnut trees can increase the number of shoots, promote flowering and increase yield.
