不同处理对沟叶结缕草追播草坪春季返青演替的影响

Effect of Different Disposals on Green Returning of Over-seeding Turf on Matrella Grass Turf

研究结果表明,提高冬前追播的播种量、提前播种期、春季返青演替阶段降低追播草坪的修剪高度等,能显著加速追播草坪的春季返青演替,并显著提高返青演替阶段追播草坪的草坪质量。冬前播种量为30g/m2的处理返青演替速度和草坪质量显著快于和优于播种量为20g/m2的处理;播种期为11月5日的处理其返青演替速度和草坪质量显著快于和优于播种期为11月16日的处理;返青阶段修剪高度为2cm的处理其返青演替速度和草坪质量显著快于和优于修剪高度为3cm的处理。

In Matrella grass green returning stage, Higher seeding rate and Earlier seeding date before winter and lower spring cutting height of the perennial ryegrass in spring resulted in faster species changing rate and higher quality of the over-seeding turf. In green returning stage in spring, the species changing rate in the turf with 30g/m^2 seeding rate was significantly faster and the turf quality was significantly better than that with 20g/m^2. The species changing rate in the turf seeded in November 5 was significantly faster and the turf quality was significantly better than that seeded in November 16. The species changing rate in the turf with 2cm cutting height was significantly faster and the turf quality was significantly better than that with 3cm.
