摘要
树冠控制,是成龄柑桔园综合栽培措施中的重要一环。幼龄期为求及早形成丰产树冠,应使植株速生快长;但进入结果期后,则须控制树冠大小,推迟封行年限,保持生长与结果的平衡;密闭封行后,更须及时修剪疏伐,改善光照条件,保持树势健壮和持续高产优质,以延长盛果年限和经济年龄。
In the past 20-25 years,there was a rapid development of citrus industry in the red soil hilly regions of Southeast China,especially in Fujian Province.However,owing to the increased planting density from 40-50 tree/mu to 60-70/mu,over crowding of the closed crowns which appeared 10-20 years after planting had caused a’decline in tree vigor as well as the quality and quantity of citrus fruits.Hence,the authors made some investigations on some typical orchards in different citrus growing regions in 1980-82.Effects of the improvement of the over crowdiness in citrus orchards by prunning,cutting back and removal of trees,which were practised by citrus growers,are discussed.
