摘要
海沃德猕猴桃春季新梢易被强风吹劈裂。试验发现早春被风吹劈裂的新梢中,长度51 cm以上的超过93%;新梢摘心抑制新梢的伸长生长,促进加粗生长,减少了新梢被风吹劈裂数量,新梢15 cm时摘心劈裂数量比CK降低8.33%;新梢延长到30 cm时摘心需加重摘心程度到10~11 cm,新梢劈裂率比CK降低8.75%。综合早春摘心处理结果,当新梢长15~20 cm时摘去顶端3~5 cm,防风的效果最好。
Shoots of Hayward kiwifruit were easily broken by strong wind in spring,and it was difficult to construct breakwind for small-scale orchard in China.Experiment results showed that 93% of shoots broken in early spring were longer than 51 cm.Pinching of shoots in early spring inhibited shoot elongation,promoted diameter increment,and pinching at 15 cm in shoot length could reduce fracture shoot number by 8.33% in comparison with the control.When pinching was elongated to 30 cm in shoot length,the shoots top should be taken off 10~11 cm and could lower broken shoots by 8.75% comparison with CK.According to above results,pinching 3～5 cm when the shoot length is 15～20 cm can make good effect.
