摘　　要：我国荔枝龙眼主产区果园树龄已有25年以上,果园郁闭封行现象严重,造成果园产量降低、果实品质变差、生产成本增加、果农收益下滑,急需应用间伐技术进行果园改造。小规模经营农户更易采用哪密砍哪的随机间伐方式,而大规模经营果场倾向于采用较为规范的果园间伐方式。从国家荔枝龙眼产业技术体系成立之后示范县间伐技术的推广应用情况来看,荔枝龙眼间伐技术应用最多的地区集中在广东茂名、湛江,广西钦州等主产区。选取位于广东省茂名市高州的荔枝示范园、茂南区的龙眼示范园进行典型案例分析,对果场实施间伐技术前后的经济效益的纵向对比分析表明,间伐后投入成本呈下降趋势,总产量、总产值逐年提升。The litchi and longan orchards in main producing areas have been over 25 years old and the canopy closure phenomenon is serious,which result in lower yield and low quality of fruit,increase of production costs,decline of farmers’ income. So it’s time to adopt thinning technology to reform the orchards. The small-scale farmers tend to choose random manner which need thinning cut,but the large-scale farms tend to use the standardized thinning way. The thinning technology have been applied widely in main producing areas,such as Maoming,Zhanjiang,Qinzhou after China litchi and longan researh system was established. Choosing a litchi demonstration located in Gaozhou and a longan orcard located in Maoming as typical cases,the results showed that the input costs decreased and total yield,output value increased year by year after the implementation of thinning technology.
