Abstract: In order to discuss effects on rice yield and soil fertility of different no-tillage cultivation ways, Agriculture Technology Promotion Station of Longyan City carried on the experiment with three years by different no-tillage cultivation ways in double cropping rice area. The result indicated that the difference about early-late season rice yield of both no-tillage cultivation in late season rice and normal cultivation was not remarkable, and the difference about the soil physical character and the nutrient condition of that was not obvious , so the no-tillage cultivation in late season rice will be promoted widely because the economic efficiency is obvious. The rice yield of no-tillage cultivation in early-late season rice was remarkable reduced than that of normal cultivation, but the soil bulk density was increased. However, the difference of the pH value, the organic matter and the primary nutrient content in soil by different tillage cultivation ways was not obvious.
