摘　　要：试验研究了诺维信生物复合肥分别与雷力果岭肥、尿素、富利禾鸡粪肥以不同比例配合施用对匍匐翦股颖(Agrostis stolonifera)绿期、地下生物量、密度及越冬率指标的影响,以期为高尔夫球场果岭秋季施肥提供参考。结果表明:各施肥处理均能促进草坪草初期生长,延长草坪绿期,诺维信∶雷力(2∶1)配合使用全年绿期最长为303 d,且与诺维信∶鸡粪肥(2∶1)的绿期和越冬率显著高于其他处理(P<0.05);地下生物量诺维信∶雷力(1∶2)显著高于其他处理(P<0.05);秋季诺维信生物复合肥与尿素按不同比例配合施用草坪密度大,显著高于其他处理(P<0.05),导致草坪徒长,枯草层增厚,延迟返青。综合各个指标,诺维信生物复合肥与雷力果岭专用肥配合施用,匍匐翦股颖越冬效果较好。This experiment was studied the effects of the different mixture proportion between Novozymes Biological Fertilizer and other fertilizers（Lei Li Special Fertilizer, Urea and poultry fertilizer）on green period, underground biomass,density and winter survival rate of bent grass in order to provide some references for fertilizer management on putting green in autumn. The results showed that all the fertilization treatments promoted growth of the bent grass at early stage, and prolong its green period as well. The mixing proportion of Novozymes：Lei Li with 2 ： 1 could prolong green period to 300 days. The proportion of Novozymes：Poultry Fertilizer with 2 ： 1 had significant effect on green period and winter survival rate than other treatments（P〈0.05）. The underground biomass under the proportion of Novozymes：Lei Li with 1 ： 2 was higher than other treatments（P〈0.05）. The treatment of Novozymes combined with Urea in autumn significantly improved density of putting green（P〈0.05）but it led to grass overgrowing and thick litter layer,as well as delayed regeneration of bent grass. Based on the integrated indicators,the Novozymes combined with Lei Li special fertilizer was better choice for improving winter survival rate.
