摘　　要：４种不同氨肥（硫酸铵、硝酸钠、硝酸铵及尿素）显著提高了帕克草地早熟禾的出叶、生长与成坪速度，增加了草坪地上、地下部分生物量，改善了草坪的外观质量。硝酸铵对草坪的分蘖和越夏能力影响最大，硫酸铵较其它３种肥料更能加快草坪生长速度，提高草坪地上、地下部生物量，加深草坪颜色。Four conventional nitrogen sources(ammonium sulphate,sodiumnitrate,ammonium nitrate and urea) were applied comparatively toanalyse the respective effects on biological and qualitative characteristics of Poa pratensis cv. Park. In comparison with the checks(without nitrogen application),the four kinds of nitrogen fertilizer effectively enhanced the leafing and growth rates andeventually accelerated the turf formation. Each nitrogen sources significantly increased the biomasses and improved the appearance of the turf. Furthermore,the ability of tilling and summer tolerance were promoted by ammonium nitrate,meanwhile,ammonium sulphate speeded up the growth, increased the biomasses and deepened the turf color.
