【摘要】 用多年生黑麦草品种过渡星在广州天河体育中心运动场的兰引Ⅲ号结缕草草坪上进行了冬绿技术试验,探讨兰引Ⅲ号结缕草草坪在我国南亚热带地区的冬季用盖播法保持绿色和运动功能的可行性及其综合效果。结果表明:冬季盖播黑麦草后,盖播处理区的结缕草草坪同没有盖播的对照区草坪相比,绿期延长,同时其它坪用性状也显著提高。从冬绿草坪的综合坪用性状来看,合理的盖播量将直接影响盖播草坪的冬季坪用性状以及夏枯时对兰引Ⅲ号结缕草草坪的伤害与恢复生长。此外,从本试验的研究结果来看,虽然冬绿草坪的综合坪用性状随着播量的增加而增加,但从整个草坪冬季的盖播效果以及盖播黑麦草夏枯时对兰引Ⅲ号结缕草草坪的影响大小等综合考虑,以30g/m2的播量较为理想。不过在具体的生产实践中,仍需要根据赛事安排以及建植管理水平酌情增减。更多还原

【Abstract】 The winter-green technology was studied on Zoysia japonica Lanyin No.3 turf use pernnial Lolium perenne named Turfstar in Tianhe gymnasium center at Guangzhou. The results showed that Zoysia japonica Lanyin 3 turf which overseeded with ryegrass has longer green-period and better turf qualities than contrast, and from the synthesis turf characters, the turf quality in winter, turf damage and renew growth in summer will be effected directly by the reasonable seed quantity. Moreover, although the synthesis turf quality will become better along with increased seed quantity, the better overseeding rate is estimated to be 30 g/m2 from the turf quality of overseeding in winter and the influence effect to Zoysia japonica Lanyin 3 turf in summer scorch. Still the best overseeding rate must increase and decrease according to the arrangement of game level, as well as planting and management in practice.更多还原
