农田土壤理化特性空间变化规律研究

Study on Soil Quality Space and Change Law in Farmland

摘要: 不同耕作措施对土壤的扰动不同，从而对土壤性质也会产生不同的影响，本研究从水平和垂直两个方向，测定关中农田土壤有机质、活性有机碳、碳酸钙等理化性质。结论如下：谢家村和辛庄村之间农田在接近村庄部分受人为干扰影响较大，农田土壤中的碳酸钙含量稳定，有机质含量发生变化后，活性有机碳部分始终保持一定含量，推测农田中土壤结构较稳定，农田中的微生物活性较高。

Abstract: Different farming measures have different disturbances to the soil, which will also have different effects on soil properties, and this study measures the physical and chemical properties of soil or-ganic matter, active organic carbon and calcium carbonate in Guanzhong farmland from both hor-izontal and vertical directions. The conclusion is as follows: The farmland between Xiejia village and Xinzhuang village is affected by man-made interference in the near village part, the calcium carbonate content in the farmland soil is stable, the organic matter content changes, the active organic carbon part always maintains a certain content, and it is speculated that the soil structure in the farmland is stable and the microbial activity in the farmland is higher.
