免耕对稻田土壤肥力的影响研究进展

Review on Influences of No-tillage on Soil Fertility of Paddy Field

免耕作为一种新型的耕作方法,目前已在中国南方稻区和其它许多国家得到应用和推广。在此,综述了免耕对稻田土壤的物理性质、化学性质和生物学性质等方面的影响的研究进展,指出了今后在该领域需要深入研究的一些问题。

The no-tillage, as a new farming technique, has been applied and practiced in paddy areas in southern China and some countries in the world. This paper reviewed already-done studies on influences of no-tillage on physical, chemical and biological characters of paddy soils, and pointed out that some further studies should be strengthened in the future.
