广西柑橘修剪技术探讨

Pruning of Citrus in Guangxi

近年来,广西柑橘产业发展迅速,但很多从业者缺乏修剪知识和技术而盲听盲从。笔者把对广西柑橘修剪几十年的研究结果和经验,包括:从幼龄树整形培育矮化多干树冠;结果树的分层上、下二层放梢,培育晚夏梢和秋梢作优良结果母枝;结果树在丰产期通过回缩与开天窗修剪,改善树冠的透光度、增加结果层的厚度等,助力广西柑橘产业高质量发展。

The citrus industry in Guangxi has been developed quickly in recent years.Pruning is very important for sustainable higher fruit yield,but has just been done randomly by many fruit growers who have less basic knowledge of pruning.Based on decades of research findings and experience in citrus pruning in Guangxi,the techniques for citrus pruning at different growth stages were described,including pruning of young citrus tree for dwarfing with a canopy of multiple limbs,pruning of mature citrus trees for growth of upper and lower layers of shoots at the late summer or autumn as fruit bearing branches,and pruning of yielding trees at the peak year to allow high light penetration and more layers of fruit branches by opening up the canopy.These pruning techniques might promote high quality development of citrus in Guangxi.
