【摘要】 针对猕猴桃较旺的生长势、枝梢年生长量大、果园管理成本急剧上升的现状而研究推广出的一种省力化夏季结果蔓修剪方式。"零芽"修剪是基于猕猴桃的"盲节"特性,对于进入结果期且较强旺的未停止生长的上位结果蔓,在其最后一果之处(之上不留芽和叶片)进行短截。"零芽"修剪后的结果蔓上不会再次抽生二次或三次蔓,失去了侧芽再次抽发旺枝的潜能。夏季"零芽"修剪可有效控制树势,合理调节生长与结果之间的关系,大大减少夏季修剪的工作量,为猕猴桃的优质丰产高效栽培提供了一项简便实用的新技术。本文阐述了"零芽"修剪的原理,并结合试验数据分析总结了"零芽"修剪的技术要点和效果。更多还原

【Abstract】 In view of the present situation of the strong growth potential of kiwifruit branches and the rising management costs of the kiwifruit orchards,’zero-bud’ pruning-a labor-saving technique in summer pruning was researched and promoted.`Zero-bud’ pruning is based on the character of the`blind-node’(node without bud) in kiwifruit and is applied only in the fruiting branches with strong growth.In fact,`zero-bud’ pruning is heading-back cut at the place of final fruit set in fruiting branch during summer pruning.As a result,the pruned branch would not stimulate the second or third vine and lost the potential of lateral vines stimulus.`Zero-bud’ pruning is effective in controlling the vigor of kiwifruit and reasonable adjusting the relationship between the vegetative growth and-fruitfulness.`Zero-bud’ pruning greatly reduces the workload of the summer pruning and provides a simple and practical new technology for kiwifruit with good quality,high yield and high efficiency cultivation.This paper expounds the principle of `zero-bud’ pruning and summarizes the key points and effects of `zero-bud’ pruning from the experimental data.更多还原
