| 摘 要： | 运用数学统计分析方法,以2006年测土配方施肥项目所测保靖县耕地土壤有机质数据进行分析,研究了保靖县耕地土壤有机质现状及其差异性。结果表明:保靖县耕地土壤有机质(SOM)为较丰富水平,平均含量为25.27 g/kg。除县域中西部大部分区域耕地土壤有机质含量处于较低水平外,北部和南部地区耕地土壤有机质含量基本处于中等偏上的水平。水稻土不同亚类土壤有机质含量状况是:潴育水稻土>潜育水稻土>淹育水稻土>漂洗水稻土;石灰土不同亚类土壤有机质含量状况是:黑色石灰土>红色石灰土>淋溶红色石灰土;山地垂直带不同亚类土壤有机质含量状况是:暗黄棕壤>黄壤性土>典型黄壤>黄红壤>红壤性土。

| Abstract: | The data of soil organic matters(SOM) in cultivated land in Baojing County,which obtained from the soil testing and formulated fertilization project of Agricultural Ministry in 2006,were analyzed by mathematical statistics method in order to study status quo of SOM in cultivated land in Baojing County and differences among different regions.The results showed that the SOM in cultivated land in Baojing County is rich with average content of 25.27 g/kg.SOM content in cultivated land of the northern and southern regions was at middle-high level,but it was at low level in central-west regions.SOM content in different subclasses of paddy soils in cultivated land ordered as waterlogged paddy soil>gleyed paddy soil>submergenic paddy soil>bleached paddy soil;SOM content in different subclasses of lime soil ordered as rendzina>terra rossa>leaching limestone red soil;SOM content in different subclasses of mountain altitudinal belt ordered as yellow-brown soil>yellow soil >typical yellow soil>yellow-red soil>red soil. |
