摘　　要：[目的]研究江西省水稻田的土壤养分现状。[方法]对江西省6个农田生态站的土壤pH值和土壤有效养分的检测结果进行分析。[结果]江西省稻田土壤普遍呈现酸化现象,全省平均pH值为5.60。重氮轻钾是普遍现象,导致肥力结构不平衡,其中碱解N含量多数处于2级以上,大部分地区缺钾严重,速效K含量多数在4、5级;有机质含量多数在2、3级,速效P分布不均衡。[结论]该研究可为农业生产部门合理施肥及种植提供依据。[Objective]The research aimed to study the status of soil nutrient in Jiangxi paddy.[Method]The soil pH value and the large number available nutrient in the six agro-ecological stations in Jiangxi Province was analyzed.[Result]The results showed that the paddy soil existed a prevalently acidification phenomenon in Jiangxi Province,and the pH value was 5.60.Casting more nitrogen and less potassium in the soil caused the fertility structure imbalance.Thereinto,The alkaline hydrolytic nitrogen content was over two grade,available potassium content was at 4 and 5 grade,organic matter content was at 2 and 3 grade,and the distributing of available phosphorus was disequilibrium in whole Province.[Conclusion]The study can provide the basis for reasonable fertilization and cultivation of agricultural productive departments.
