过渡地带建植常绿草坪的探讨

过渡地带草坪建植面临两难的选择,可选用冷季型草,也可选用暖季型草,但均不理想.综合分析认为,暖季型草坪草中的结缕草和冷季型草坪草中的高羊茅为过渡地带建坪的首选草种.解决过渡地带结缕草冬季枯黄问题采取2种途径:一种是在每年秋季盖播黑麦草、粗茎早熟禾或匍匐紫羊茅等冷季型草形成过渡性的季节草坪;另一种是与高羊茅混植建立稳定的持久性草坪.后一种途径其技术目前尚未成熟,仍处于研究探索阶段.

An approach to turf establishment for all-year green in the transition zone

Based on the comprehensive analysis of turf establishment data in the transition zone,the authors found the turf grasses best adapted to the transition zone climate were Zoysia japonica and Fescue arundinacea.The brown color found in Z.japonica was due to dormancy during the winter and could be solved by the following two techniques:one option was to over-seed with either Lolium perenne,Poa trivialis,or creeping Fescue rubra in the autumn,this was done in order to provide a temporarily seasonal turf.The other option was to establish a stable and permanent polystand turf by mixing Z.japonica with F.arundinacea.The latter option was currently being studied but as yet was not used commercially.
