摘　　要：经过4 a的低改试验,总结提出了对油茶低产林增产效果较好的垦复方式为夏季穴垦并浅垦+冬季全垦并深垦;施肥组合为3月份施氮、磷、钾复合肥(氮磷钾21-6-13)750 kg/hm2+7月份施氮、磷、钾复合肥(氮磷钾17-17-17)750 kg/hm2+10月份施有机肥15 000 kg/hm2和氮、磷、钾复合肥(氮磷钾20-5-10)375 kg/hm2,综合改造措施是挖蓄水平台+清除杂灌+密林疏伐和稀林补植+整形修剪+截干萌芽和预植更新+高接换冠+垦复+合理施肥。After 4 years of reforming low-yield forest of Camellia oleifera, the paper summarizes and propo- ses the best reclamation mode （hole and shallow reclamation in summer ＋ whole and deep reclamation in winter）, fertilizer combination （nitrogen, phosphorus and potassium compound fertilizer （2l-6-13） 750 kg/hm2 in March ＋ nitrogen, phosphorus and potassium compound fertilizer （17-17-17） 750 kg/hm2 in July ＋ organic fertilizer 15 000 kg/hm2 and nitrogen, phosphorus and potassium compound fertilizer （20-5-10） 375 kg/hm2 in Oetober） as well as comprehensive renovation measures （ dig water storage platform ＋ removal weeds and bushes ＋ thinning and replan- ting ＋ pruning ＋ stem cutting-off and plant update ＋ high position stem cutting-off ＋ reclamation ＋ fertilization reason- ably） , and provide reference for reforming low-yield forest of C. oleifera in Meizhou city.
