坡位对木荷不同径级根生物量和含水率的影响

摘要

[Objective]To study the effect of different sites on biomass and moisture of root in different diameters of Schima superba.[Method]Stateowned forest farm in Wuyishan of Long Beach as the test ground,set uphill,middle and downhill slopes,diameter root fresh biomass,dry biomass,water content of Schima superba were determined.[Result]The results showed that differences of fresh biomass,dry biomass,moisture in different sites was signigicant (P ＜0.05).Distribution of fresh biomass in different sites was the same with dry biomass,distribution between diameters as well,different with moisture.[Conclusion]The study can provide theoretical basis for reasonable planting Schimna superba in hillside.%[目的]研究不同坡位对木荷不同径级根生物量和含水率的影响.[方法]以武夷山市长滩国有林场为试验地,分别设上、中、下3个坡位,测定木荷各径级根鲜生物量、干生物量、含水率.[结果]不同坡位间,木荷根部鲜生物量、干生物量、含水率均差异显著(P＜0.05).木荷根鲜生物量在不同坡位的分配规律与干生物量一致,且各径级鲜生物量和干生物量分配规律一致,而含水率情况与生物量分配不同.[结论]该研究可为木荷合理种植于山坡提供理论依据.
