- 摘要:
- 以8年生“海沃德”猕猴桃品种为试材，设置了强旺结果枝在结果部位之上留3～4叶进行摘心、强旺结果枝在结果部位之上留7～8片叶进行摘心和强旺结果枝进行捏尖控长等3个处理，通过枝蔓生长量、二次梢的发生率、翌年枝萌发率、结果能力、劳动力投入等的调查及叶片相关指标、果实品质指标测定，研究了不同夏季修剪方法对猕猴桃生长及结果的影响。结果表明：枝蔓夏季修剪以捏尖处理劳动力投入少，果实产量高，质量好，翌年结果能力强，综合效果最优；强旺结果枝结果部位以上留7～8叶摘心与捏尖处理在树体翌年萌芽、结果能力无显著差异，但是劳动力投入（二次梢发生率）较高，品质较差，综合效果次之；强旺结果枝结果部位以上留3～4叶摘心处理的劳动力投入（二次梢发生率）最高，果实产量较低、品质较差、翌年萌发、结果能力差，综合效果最差。说明枝蔓夏季修剪以捏尖处理最适合“海沃德”猕猴桃的生长。
- Abstract:
- Eight-year-old kiwifruit（Actinidia deliciosa var.deliciosa cv.Hayward） was used as materials to investigate the effects of different summer pruning（keeping 3—4 leaves to top removal,keeping 7—8 leaves to top removal and tip squeezing on the strong-fruiting shoot） on shoot growing,fruit yield,fruit quality,germination and bearing capacity in the ensuing year,labor input etc.The results showed that the comprehensive results of tip squeezing on the strong-fruiting shoot of ‘Hayward’ kiwifruit was the best,secondly with keeping 7—8 leaves to top removal,and keeping 3—4 leaves to top removal was the worst.Treatment of tip squeezing on the strong-fruiting shoot was suited for ‘Hayward’ kiwifruit under summer pruning.
