今年3月12日,正当全市上下开展内容丰富的植树活动时,大驿坝滨江路上64棵桂圆树却因遭到不同程度的环割而闹得沸沸扬扬,市政协领导也亲自过问此事,泸州电视台也对此进行了全程跟踪报道。且不说管理业主在李焱平高级农艺师的指导下对这批古树名木(泸州市风景园林管理局在2005年通过鉴定,已将这批桂圆树列为古树名木进行挂牌保护)采用环割技术处理,程序上不符合有关法律、法规要求,单从技术上讲也非常值得商榷。桂圆也称龙眼,是泸州市市树,也是我们泸州栽培甚广的亚热带水果,栽培历史千年以上,形成了一套较为完善的栽培技术。在果树栽培中,通过环剥、环割和环扎技术,能够切断叶片制造出来的碳水化合物通过皮层向根系的输送,使之积累在枝芽上,促进新梢老熟,抑制冬梢萌发,有效地促进花芽分化、成花和坐果,从而提高产量。从作用机理分析,在果树栽培上采用环割技术是可行的。但必须合理选择环割对象和部位,掌
March 12 this year, just when the city up and down to carry out rich tree planting activities, Dam Road, Binjiang Road, 64 trees were due to varying degrees of ring cut and aroused uproar, the CPPCC leaders also personally asked the matter, Luzhou TV stations also conducted a full tracking report on this. Not to mention the management of the owners of senior agronomist Li Yanping under the guidance of these old trees (Luzhou Landscape Architecture Authority in 2005 through the identification of these old trees have been listed as ancient and famous tree protection ) Ring cutting technology to deal with, the program does not meet the relevant laws and regulations, single from the technical is also very questionable. Longan, also known as longan, is the city of Luzhou City, Luzhou is also a very wide cultivation of subtropical fruits, cultivation history of more than a thousand years, forming a relatively complete set of cultivation techniques. In the fruit tree cultivation, through the girdling, ring cutting and cerclage technology, can cut off the leaves of the carbohydrate produced by the cortex to the root of the transport, so that the accumulation in the buds, promote new shoots mature, inhibit winter shoot germination, Effectively promote flower bud differentiation, flower and fruit set, thereby increasing production. From the mechanism of action analysis, fruit ring cultivation using ring cutting technology is feasible. However, it is necessary to rationally choose the objects and parts of the circumcision
