为了探讨羊粪施用量对多花黑麦草生产性能和氮素生产效率的影响，以3个多花黑麦草品种为材料，采用5种羊粪施用梯度进行田间试验。结果表明：在0～60 t／hm 2范围内，随着羊粪施用量的增加，多花黑麦草的分蘖数、株高、产量、粗蛋白含量均能显著提高，但氮素的生产效率逐步降低，且3个品种间的差异不显著（P＞0．05）；证实3个品种均适合利用羊粪种植，在多次刈割条件下，最佳羊粪施用量为45～60 t／hm 2（折合纯氮778．5～1038 kg／hm 2）。%Field experiments were conducted to study the effects of 5 goat manure application rates on the productive perform -ance and nitrogen producing efficiency of 3 Italian ryegrass varieties.The results indicated that: along with the increase in the appli -cation rate of goat manure within the scope of 0~60 t/hm2 , the tiller number, plant height, yield and crude protein content of three ryegrass varieties all significantly increased , while the nitrogen producing efficiency gradually decreased .There were no significant differences in productive performance and nitrogen producing efficiency among 3 ryegrass varieties.So, goat manure application was suitable for the planting of these 3 ryegrass varieties.The best application rate of goat manure for ryegrass production was 45~60 t/hm 2(equivalent to pure nitrogen 778.5~1038.0 kg/hm 2 ) under the condition of multiple clipping .
