摘  要：
为探究花岗岩发育的江西油茶林红壤(以下简称江西红壤)与紫色岩发育的福建油茶林土壤(以下简称福建紫色土)在养分状况上的差异,以高粱作为指示植物,采用常规分析、吸附试验和盆栽试验法比较分析了两类土壤的养分限制因子。研究结果表明:江西红壤有机质含量高于福建紫色土;两类土壤的元素组成中,均以S元素最为丰富,而P、K、Ca、Mg及硝态氮养分元素含量均较低。除Mn和Zn外,其它养分元素含量均为江西红壤≥福建紫色土;两类土壤对P的吸附固定能力均最强,江西红壤与福建紫色土分别对Mn和B的吸附最弱。盆栽试验结果表明N、P、Ca是江西红壤的主要限制因子,Fe、Cu、K、Mo是潜在的养分限制因子;N、P、Ca、Mg是福建紫色土的主要限制因子,Mg、Zn、Fe、S、K是其潜在的养分限制因子。

摘  要：
In order to explore the difference in nutrient status between Red Soil derived from granite in Camellia Oleifera forest of Jiangxi and Purple Soil derived from purple rock in Camellia Oleifera forest of Fujian,the routine analysis,adsorption experiment and pot experiment of sorghum were used to comprehensively analyze the nutrient limiting factors in the two soils.The results showed that the content of organic matter in Red Soil of Jiangxi was higher than that in Purple Soil of Fujian.S element in the two soils was the most abundant,while the contents of P,K,Ca,Mg and nitrate nitrogen were low.The contents of nutrient elements except for Mn and Zn were higher in Red Soil of Jiangxi than in Purple Soil of Fujian.The two soils had the strongest adsorption capacities of P,while had the weakest adoption of Mn and B.As a result,N,P and Ca were the main limiting factors and Fe,Cu,K and Mo were the potential limiting factors in Red Soil of Jiangxi Province,while N,P,Ca and Mg were the main limiting factors and Fe,S,K were the potential nutrient limiting factors in Purple Soil of Fujian Province.
