摘　　要：分别利用沼液、发酵羊粪、尿素进行杂交狼尾草施肥试验,结果表明施用沼液、羊粪的处理与对照尿素处理相比,在牧草产量方面差异不显著,各处理的牧草生长势相当,施用沼液的处理与对照相比,提高了牧草的品质。施用沼液年可节约成本1650元.hm-2,并改善了土壤结构,经济、生态效益得到明显提高,促进了种草业的可持续发展。Trails of organic manure fertility on grass forage Pennisetum amer/canum x P. purpureum CV. was conducted by applying fermented biogas slurry and goat dung respectively with urea as control . The results showed that no significant different in forage biomass production among them, but the forage quality adopted with biogas slurry was improved comparing with control, the annual cost saving reached RMB 1650 yuan·hm^-2. The soil structure improved so obviotrs that ecological and economic benefits were ob- tained.
