| 摘 要： | 对福建省长乐市大鹤国有林场的4年生大叶相思、肯氏相思、纹荚相思、厚荚相思、卷荚相思的各构件生物量分配率进行研究,结果表明:厚荚相思的总生物量最大,而卷荚相思的总生物量低于其他相思树种。5个相思树种各构件生物量分配率:肯氏相思、纹荚相思和卷荚相思的根部分配率较高,其中纹荚相思的根系生物量分配率最高,达46.69%,其次为肯氏相思,达44.59%;而大叶相思和厚荚相思的枝叶鲜重和生物量分配率较高,其中厚荚相思枝叶生物量最高,达76.71%,大叶相思达75.05%。从构件生物量的角度来看,肯氏相思和纹荚相思更适宜作为滨海沙地造林树种。

| Abstract: | In order to study the growth situation of Acacia species in southeast coastal shelter forest in Fujian,biomass distribution rates on modules of 4-year-old Acacai auriculiformi,A.cunninghamii,A.crassicarpa,A.aulacocarpa,and A.cincinnatai in Changle Dahe State-Owned Forestry Centre were studied.The result showed that the total biomass of A.crassicaipa was the largest,but A.cincinnatai was the opposite.Distribution rates of root of A.cunninghamii,A.aulacocarpa and A.cincinnatai were higher than those of A.crassicarpa and A.auriculiformis,and the largest was A.aulacocarpa,46.69%;the second was A.cunninghamii,44.59%.But distribution rates of leaf and branch of A.auriculiformis and A.crassicarpa were higher than those of the other 3 species,the largest was A.crassicarpa(76.71%),then A.auriculiformis(75.05%).In the sense of module biomass,A.crassicarpa and A.auriculiformis were superior to the other 3 Acacia trees on southeast coastal sand. |
