| 摘 要： | 通过田间条件下砂滤管试验，研究了不同膨润土施用量及有机物料对砂土土壤含水量和有机质含量的影响。结果表明，施用膨润土和有机物料能显著地提高砂土土壤含水量和有机质含量，且二者存在明显的交互作用，差异达极显著水平，施用膨润土能明显增加土壤有机质的累积是，说明在施用同样有机物料的前提下，施用膨润土可有显著提高砂土土壤有机含量。

| Abstract: | The effects of different level bentonite on the content of soil water and soil organic matter in the field are studied with the sandy sieve tube method.The result showed that the use of bentonite and organic matter could improve the content of sandy soil water and soil organic matter.The analysis of variance showed a significant difference.The use of bentonite can increase the accumulations of soil organic matter,which indicates bentonite can improve soil organic matter content by using the same level of organic matter as control. |
