摘要
[目的]为草坪在新的生命周期生长奠定良好的基础和提供原动力。[方法]研究不同灌溉次数对草坪草返青的影响。[结果]在西宁地区春季草坪草返青前进行4次灌溉与同一灌水量(5kg/m2)下进行1、2、3次灌溉相比,灌溉4次的地下生物量、地上生物量、叶片色泽、质地、密度和返青日期均有明显提高,在此灌溉条件下能使草坪草返青后的坪用性状达到良好的品质。[结论]在西宁地区对草坪草返青期灌溉应以4次较为合理;灌水量为20kg/m2。
[Objective] The aim was to laid the foundation and provide the generative force for lawn growth in the new growth of the life cycle.[Method] The effects of irrigation times on turfgrass reviving were studied.[Result] The study showed that turfgrass in the spring of Xining being irrigated 4 times compared with 1,2,3 times before turning green with the same irrigation（5 kg/m2）,the ground biomass,aboveground biomass,leaf color,texture,density and the reviving date had the significant improvement,turfgrass could achieve good quality after reviving under the irrigation condition.[Conclusion] In Xining region,the irrigation should be 4 times and the irrigation should be 20 kg/m2 in reviving period.
