摘　　要：在长江中下游气候过渡带地区,暖季型草坪交播冷季型草坪草是延长草坪全年绿色的技术保障。本研究以建植3年的杂交狗牙根328为基础草坪,在秋季交播多年生黑麦草,测定了春季返青演替阶段修剪频率对交播草坪演替的影响。试验结果表明,狗牙根草坪交播多年生黑麦草,春季采用的修剪频率会促进狗牙根的生长,从而加速了草种的演替。In the middle and lower reaches of Yangtze River, a climate transition zone, cross-sowing of cool-season turfgrass for the warm-season lawn is a technical support for extending green period all the year round. In the study the basic lawn, a 3-year-old lawn established with hybrid 328 Bermuda grass, was cross-sown with perennial ryegrass in autumn. The effects of pruning frequency on the succession of the cross-sown lawn were measured in spring green-up succession period. The results showed that the pruning frequency adopted in spring for the Bermuda lawn with cross-sowing of perennial ryegrass could promote growth of Bermuda grass and speed up the succession of the grass species.
