The results showed that the six cultivation patterns showed small effects on the occurrence of rice sheath blight, second-generation rice planthopper, rice stem borer and rice false smut, but showed great effects on the occurrence of rice leaf folder, third-and fourth-generation rice planthopper and weeds; there were certain differences in the rice yield among different cultivation patterns, and the rice yield under the pattern of mechanical plowing-mechanical transplanting ranked first, while that under the pattern of cattle plowing-scattered transplanting ranked last.展开更多
