摘　　要：在贪瘠的弃荒地使用不同组合的基肥探讨对牧草产量和质量的影响。结果表明,在相同的肥水管理条件下,以“复合肥+牛粪+石灰”基肥组合(A处理),可使多花黑麦草(特高)、多年生黑麦草(保利)的年产草量分别比“猪粪+牛粪+石灰”的基肥组合(B处理)提高10.6%和29.2%,差异显著(p<0.05);粗蛋白质、粗脂肪、粗灰分分别有所提高;粗纤维、无氮浸出物有所降低。Different combinations of base fertilizers were used in Culture of two forage grasses on degrade land.Treatments with base fertilizers were 'compound fertilizer + cattle dung + lime'(combination A) and 'pig dung + cattle dung + 1ime' (combination B).The experiments showed that annual yields of Annual Ryegrass and Perennial Ryegrass with A were significantly higher than those with B by 10.6% and 29.2%,respectively(p<0.05).Crude protein,crude fat and crude ash were s1ightly higher than those with B,respectively,but the Crude fiber and N-free extract were slightly lower.
