摘    要:根据第二次全国土壤普查资料,利用数理统计的方法研究了华北黄泛平原潮土土壤粒级与土壤养分含量之间的关系。研究结果表明,土壤耕层养分含量与土壤砂粒成负相关,与小于0.01mm的各粒级成正相关。其中土壤有机质含量主要受砂粒(1~0.05mm)和细粘粒(〈0.001mm)含量的影响,土壤全氮含量主要受细粘粒含量的影响,土壤全磷含量主要受砂粒和粗粉粒(0.05-0.01mm)含量的影响,土壤速效磷含量主要受细粘粒含量的影响,土壤速效钾含量主要受细粉粒(0.01,0.005mm)含量的影响。

关 键 词:潮土  土壤养分  相关分析  逐步回归  黄泛平原

Abstract:Based on the data of fluvo - aquic soils published by provincial government, this paper analyzed the relations of nutrients with particles using methods of correlation. It was found out that the contents of nutrients were in proportional to the contents of particles less than 0.01 mm, inversely proportional to the contents of sand. Some models were established using the method of stepwise regression. These models showed, the level of organic materials was mainly affected by the content of sand and fine clay particles, total nitrogen by fine silt, total phosphorus by sand and coarse silt, rapidly available phosphorus by fine clay, and rapidly available potassium by fine silt, respectively.
Keywords:fluvo - aquic soil  soil nutrient  correlation analysis  stepwise regression  Yellow River flood plain
