4个品系软枣猕猴桃花期不同程度新梢摘心的效应

以4个品系软枣猕猴桃LD107、LD133、LD243、LD1214为试材,在花期分别对营养梢、结果梢进行摘心处理,研究不同摘心程度的效应。结果表明,花期新梢摘心处理能提高摘心梢翌年的萌芽率及结果枝率,LD107、LD243、LD1214这3个品系的营养梢留30cm,结果梢留7叶摘心更有利于提高结果枝率,LD133品系营养梢留50cm,结果梢留3叶摘心更有利于形成结果枝;新梢摘心后形成的营养枝率无显著差异。

Effects of pinching treatments of four Actinidia arguta strains at their blooming periods

In order to explore the appropriate pruning techniques of the Actinidia arguta in summer,the Actinidia arguta LD107,LD133,LD243 and LD1214 were used as experimental materials.The vegetative and fruiting shoots were pinched for different degrees processing during flowering period.The results showed that the germination rate and fruiting shoots rate of the next year could be improved by the treatment of new shoots at the flowering period.The vegetative shoots were left with 30cm and the fruiting shoots were left seven leaves could improve the fruiting shoots rate of LD107,LD243 and LD1214.While the vegetative shoots of LD133 were left with 50cm,and the fruiting shoots were left three leaves,which were more conducive to the formation of fruiting shoots,but there was no significant effect on the vegetative shoot rate.
