对5种不同土壤类型的橡胶林地土壤肥力及酶活性特征进行了研究,主要结果表明:在供试土壤中,土壤养分肥力以暗红湿润铁铝土(A土类)的最高,以酸性湿润雏形土(D土类)最低;土壤酶活性以暗红湿润铁铝土(A土类)的最高,以粘化湿润富铁土(C土类)或酸性湿润雏形土(D土类)的最低,湿润富铁土(B土类)和铁质湿润雏形土(E土类)酶活性相差不大.土壤酶活性与土壤肥力因子大部分呈显著或极显著正相关.

The soil fertility and soil enzyme activities were determined in rubber plantations with 5 different soil types: Pho-udic Ferralisols (A), Udic Cambisols (B), Arg-udic Ferrisols (C), Aci-udic Cambisols (D) and Iron-udic Cambisols(E). The results show that the soil fertility is highest in the soil A and lowest in the soil D, and that the soil enzyme activity is maximum in the soil A, and minimum in the soil D or C, but moderate in the soil B and E without much difference between the soil types B and E. The soil enzyme activities were significantly or highly significantly correlated with most of the factors of soil fertility. Therefore, the soil enzyme activity can be used as a bio-active index for evaluating soil fertilities in rubber plantations with different soil types.
