几个树种枝叶水浸液处理杉木6年后其生物量及分配

分别用杉木、木荷、丝栗栲，马尾松枝叶不同浓度水浸液处理杉木6年后测定其各器官的生物量及其分配，结果表明丝栗栲，马尾松，木荷水浸液处理杉木6年后，各器官的生物量有不同程度的提高，随着浓度加大其促进作用增强，在低浓度时有利于皮、枝和枯枝落叶生物量分配率，高浓度时有利于叶、根、干的生物量分配率，杉木水浸液处理杉木6年后，各器官生物量有不同程度的降低，随着浓度加大其抑制作用增加，在低浓度时有利于叶、皮、根，枝和干等各器官生物量分配率，高浓度时有利于枯枝落叶生物量分配率。

Biomass and its distribution of Chinese-fir treated with aqueous extracts of several tree species after six years

The biomass of different organs and biomass distribution of Chinese fir treated with aqueous extracts of the Cunninghamia lanceolata,Schima superba,Castanopsis fargesii and Pinus massoniana under different concentrations after six years was measured.The result showed that the biomass of different organs of Chinese fir treated with aqueous extracts of Schima superba,Castanopsis fargesii and Pinus massoniana after six years were increased in some degree,the higher the concentration was,the higher the positive effect was,and low concentration had positive effect on the bark,branch and litter biomass distribution,high concentration had positive effect on the leaf,root and stem biomass distribution;That the biomass of Chinese fir treated with Cunninghamia lanceolata after six years were decreased,the higher the concentration was,the higher the inhibited effect was,and low concentration had positive effect on the leaf,bark,root,branch and stem biomass distribution,high concentration had positive effect on the litter biomass distribution.
