摘　　要：通过对邓恩桉人工林施用腐植酸桉树系列有机专用肥后林分光合特性的试验研究,结果表明:在相同立地条件下与常规化肥处理相比,施用专用肥的林分叶面积指数提高了17.6%～23.8%;叶绿素a、叶绿素b和总叶绿素含量分别提高了18.8%～27.2%、23.2%～47.4%和19.9%～32.2%;日平均净光合速率提高了15.6%～24.6%;其中尤以处理Ⅳ即每株施用腐植酸桉树基肥专用500g配合复合微生物菌剂10g作基肥+腐植酸桉树追肥专用2号500g作追肥的林分叶面积指数最大,叶绿素含量最高,光合作用能力最强,是适合福建北部地区的较佳施肥模式。Study on effect of HA as special organic fertilizer on photosynthesis property of Eucalyptus dunnii stands showed that compared with that same site condition treated by common fertilizer, leaf area index increased by 17.6% - 23.8%, chlorphyll a and b and total chlorophyll by 18.8% -27.2%, 23,2% - 47.4% and 19.9% - 32.2%,mean daily net photosynthetic rate by 15.6% - 24.6% treated by HA. Espcially treatment IV had the best result of leaf area index, chorophyll and photosynthesis capacity,it was an ideal fertilization mode in the northern Fujian.
