冬季盖播狗牙根草坪的春季转换研究进展

Research Progress on Winter Overseeding and Spring Transition of Bermudagrass Turfgrass

狗牙根(Cynodon dactylon)草坪冬季盖播冷季型草种[主要是多年生黑麦草(Lolium perenne)]是高尔夫果岭、发球台等高水平维护草坪的一项常规养护措施。但是,冬季盖播造成狗牙根返青和生长困难,草坪生长衰弱,草坪品质低劣。目前对于促进狗牙根盖播草坪春季转换的研究相对较少,国内基本上还没有这方面的研究报道。本文综述了盖播对狗牙根草坪的影响,以及促进盖播冷季型草坪向狗牙根草坪转换的养护措施,包括盖播草种的选择及播量、过渡转换期养护管理、狗牙根春季补播及种内转换(Interseeding)、生长调节剂应用和冷季型草坪的化学防除等,以唤起国内对盖播草坪的春季转换问题的重视,加强对其技术的引进、消化、吸收和创新研究。

Winter seeding on dormant bermudagrass is a routine culture mangement on high maintain turf such as green or tee of golf course.But winter overseeding has resulted in poor greenup and growth on bermudagrass turfgrass in the coming year,which leads to bermudagrass turfgrass wither and misfunction.In this paper,we summarized both the damage of winter overseeding to bermudagrass and the measure which facilitated overseeded cool season turfgrass transition to bermudagrass turfgrass,including overseeding species selection and rate,cultural management within spring transition,bermudagrass spring overseeding and interseeding,the application of PGR and herbicide to control cool-season turfgrass.In the end,an issue about winter overseeding on bermudagrass was arised.
