摘要
[目的]研究不同坡位5年生无患子人工林生物量及结实量差异,为无患子科学合理种植提供理论依据.[方法]以5年生无患子人工林为研究对象,通过野外样地调查,分析不同坡位对无患子生长量、生物量及结实量的影响.[结果]不同坡位无患子林分乔木层地上部分生物量变化范围在4 370.22 ～ 21 456.08 kg/hm2,根系生物量变化范围在3 507.69～8 898.01 kg/hm2,林下植被层生物量变化范围在11 167.23 ～ 18 084.24 kg/hm2,林分结实量变化范围在180.01～ 384.03 kg/hm2.[结论]无患子林分生长量、林分生物量及林分结实量均表现为下坡位最大,中坡住居中,上坡位最小.
Abstract
[Objective] To research the differences in biomass and cone crop of five-year-old Sapindus mukorossi plantation under different slope positions,and to provide theoretical foundation for the rational and scientific planting of S.mukorossi.[Method] With five-year-old S.mukorossi plantation as the research object,effects of slope position on the growth,biomass and cone crop of S.mukorossi were analyzed based on the investigation of field sample plot.[Result] Change range of aboveground part biomass of arbor layer was between 4 370.22 and 21 456.08 kg/hm2.Change range of underground part biomass was 3 507.69-8 898.01 kg/hm2.The change range of understory vegetation biomass was 11 167.23-18 084.24 kg/hm2.Change range of stand fruit setting amount was 180.01-384.03 kg/hm2.[Conclusion] Stand growth,stand biomass and stand cone crop of S.mukorossi are in the order of lowslope ＞ midslope ＞ upslope.
