摘　　要：2007-2008年进行了厩肥和尿素配合施用对新植鸭茅Dactylis glomerata栽培草地鲜草产量的影响研究,结果表明,在经历了2008年年初持续20多天雪凝灾害之后,6个厩肥和尿素处理组合的鲜草产量差异显著,施厩肥30000kg/hm2与施尿素75、175、275kg/hm2的处理组合的鲜草产量均极显著高于对照,厩肥施用量30000kg/hm2的处理组合鲜草产量较高,其中,鲜草产量最高的施肥组合为厩肥30000kg+尿素175kg/hm2,而最经济的施肥组合应该是厩肥30000+尿素75kg/hm2。The impact of manure and urea on the fresh yield of Dactylis glomerata after snow disaster was studied in 2007 and 2008. The results showed that the fresh yields among 6 manure and urea treatments were significant different after 20 days snow disaster. The yields of manure treatment （30 000 kg/hm^2） and urea treatments （75 kg, 175 kg, 275 kg） were significant higher than the control. The fresh yield in the treatment of manure （30 000 kg/hm^2） ＋ urea （175 kg/hm^2） was the highest. And the economic fertilization formula was 30 000 kg/hm^2 of manure ＋ 75 kg/hm^2 of urea.
