摘要
于2005年1月-12月对重庆市北碚区结缕草草坪中的杂草进行了调查,以确定该地区结缕草草坪中常见杂草的种类及其发生规律。结果表明,常见的草坪杂草隶属24科有56种,其中,香附子(Cyperus rotundus)、破铜钱(Hydro-cotyle sibthorpioides)、红花酢浆草(Oxalis corym bosa)、马唐(Cephalanoplos segetum)、繁缕(Stellaria m edia)等最为常见,同时也是草坪杂草中的优势种。杂草每年有2个发生高峰期,即春夏发生高峰期和秋冬发生高峰期,其中春末夏初草坪中的杂草种类多、数量大,危害最为严重。
In an investigation carried out in Beibei, Chongqing in 2005, the weeds on Zoysia japonica turf were sorted out and the patterns of their occurrence were studied. 56 common species of turf weeds belonging to 24 families were identified, of which Cyperus rotundus, Hydrocotyle sibthorpioides, Oxalis corymbosa, Cephalanoplos segetum and Stellaria media were dominant species. Two climax periods of occurrence for the weeds were late spring to early summer and fall to early winter. In late spring and early summer, the weeds appeared in great amount and caused great damage to the turf.
