摘要：In order to probe the influence of different ridge tillage planting mode of summer maize, the study has beenconducted on leaf area index, ground dry matter accumulation and yield of contrast. The results indicate thatin the whole growth period of summer maize, leaf area index of ridge tillage cultivation is increased relative tothat in traditional flat cultivation. The maximum difference is 0.43. Leaf area index of trapezoidal ridge tillagecultivation is higher than that of V-ridge, with the biggest difference of 0.23. Ground dry matter accumulationand yield of ridge tillage cultivation are higher than traditional flatten culture, and the planting mode of trapezoidalridge tillage is better than V-ridge tillage. On the basis of the experimental results, it is suggested that thetrapezoid ridge tillage planting of summer corn is suitable to extend widely in the western region of China.
