摘要
[目的]以金寨县测土配方项目测定的不同区域农田土壤有机质含量为研究对象,分低山区、中山区和丘岗区3种地形地貌,研究该县农田土壤有机质含量的分布差异。[方法]采用GB9834-88法测定有机质含量。[结果]该区域农田土壤有机质含量存在时间和空间差异,3～4月份高于12月份,中山区明显高于低山区和丘岗区。对土壤有机质丰缺程度的分析则表明该地区农田土壤有机质处于中偏低水平,土壤比较贫瘠。[结论]根据试验结果提出金寨县土壤有机质含量差异主要存在于内部环境条件,测定应以12月份的有机质含量为准。
[ Objective ] The content is measured by Jinzhai Country testing soil for formulated. Studied distribution difference of agricultural soil organic matter content in the country. [ Method ] Adopt method of GB9834 - 88 to determine organic content. [ Result ] The agricultural soil matter content exists differences of time and space in the region. The content in March and April is higher than in December. The conent in the mountainous areas significantly higher than in the hilly area and low mountains. It shows that the agricultural soil organic matter in the region belongs to middle and low-level through analying lack or abundance of soil organic matter. The soil is relatively infertile. [ Conclusion] According to test results the difference of soil organic matter content in Jinzhai country mainly exists the internal environmental conditions. The determination should take organic matter content in December as standard.
