摘要 采用土壤养分状况系统研究法,对海南岛两大典型香蕉种植园土壤进行了土壤的吸附特性研究。结果表明:①不同土壤对不同营养元素的吸附固定能力不同:②两种土壤对K、Cu、Zn的吸附固定作用比较弱,两者对Cu、Zn的吸附固定能力较接近,但对K的吸附固定作用有着明显的不同。③燥红土对P的吸附固定作用较强;④两种土壤部对B有着很强的吸附固定作用,其中燥红土在2~4μg/ml浓度时对B有着极其强烈的吸附固定作用;⑤砖红壤对0~80μg/ml浓度的S的吸附固定能力很强。而燥红土对S的吸附固定则比较弱;⑥砖红壤对0~5μg/ml内的Mn有着强吸附,燥红土对0~20μg/ml内的Mn有强吸附。 The soil nutrient systematic study method was employed in this paper to study characteristics of soil nutrient adsorption in two big typical banana plantations on Hainan Island. Results showed: (1) The two soils varied sharply in nutrient adsorbing capacity with nutrient; (2) Though both were quite weak in capacity of adsorbing K, Cu and Zn, and quite similar to each other in capacity of adsorbing Cu and Zn, they differed significantly in K adsorbing capacity; (3) Dry red soil was rather strong in P adsorbing capacity; (4) Both were very high in B adsorbing capacity, and especially when B content ranged between 2 - 4 μg/ml in dry red soil; (5) Latosol was very high in S adsorbing capacity particularly when S content was in the ragne of 0 - 80 μg/ml, but dry red soil was quite low; and (6) both latosol and dry red soil were high in Mn adsorbing capacity when the content of Mn was in the range of 0 - 5 μg/ml and 0 - 20 μg/ml, respectively.
