【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。更多还原

【Abstract】 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/hm2)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/hm2)+ urea(175 kg/hm2)was the highest.And the economic fertilization formula was 30 000 kg/hm2 of manure + 75 kg/hm2 of urea.更多还原
