| 摘 要： | 以原状土壤为试验对象,基于传统常压测定法设计出一种简单而准确的土壤透气速率测定方法。研究结果表明:该方法克服了传统常压测定法变压测定过程导致精度降低的问题,同时又具备简单易行的优点。运用该方法对长期定位试验土壤进行研究,发现长期配施有机无机肥可提高红壤稻田耕作层土壤透气速率,改良土壤通透性。

| Abstract: | New equipment was built to measure the soil gas permeability, compared with the traditional recommended method, the accuracy of the measurement was significantly improved as gas flow was managed to be constant in the new method. A case study showed that long-term application of organic amendments not only increased soil porosity, but improved soil gas permeability. |
