生态农业对土壤有机质的影响

为了促进现代农业向生态农业转型,采集了某地现代农业和生态农业种植模式下的土壤进行了有机质的测试分析,并对有机质测定的方法进行了改进。改进后的测试方法污染小、设备简单、操作简便、快速准确,适用于大批样品的分析,基层环境检测单位的分析工作者可以参考使用。有机质测试数据显示,生态农业种植模式土壤中的有机质含量较现代农业高35%,这说明生态种植模式显著增加了土壤中有机质含量,生态农业对土壤肥力的影响优于现代农业。

Effect of Ecological Agriculture on Organic matter in soil

In order to help modern agriculture transfer to ecological agriculture, we collected the soil under the planting mode of modern agriculture and ecological agriculture, then tested the organic matter in soil samples by the improved determination method of organic matter (O.M.). The improved determination method is excellent in less pollution, simpler equipment and operation, less time spending and more accurate date obtaining, and is more suitable for the analysis of a large number of samples. The organic matter content in soil of ecological agriculture was higher than that of traditional planting, which indicated that ecological planting model significantly increased the content of organic matter in soil, and the effect of ecological agriculture on soil fertility was better than that of modern agriculture.
