摘 要:探讨了退化坡地的改造利用和不同基肥组合处理退化坡地对牧草生产的影响,试验结果表明:在相同的肥水管理条件下,以“鸡粪+牛粪+石灰”基肥组合(A)处理退化坡地土壤,可使皇草、杂交狼尾草、矮脚象草和墨西哥玉米的年产量比“猪粪+牛粪+石灰”组合(B)处理分别高出9.7%、12.8%、43.0%和9.9%,前者(A)生产出的牧草的粗蛋白含量略高于后者(B),粗纤维含量略低于后者,而粗灰分含量显著高于后者。 |

摘 要(英文):×P. typhoideum , Pennisetum americanum × P. purpureum, Pennisetum purpureum Shchum. and Euchlaene mexicana, Schbrad cultured with A were higher than those with B by 9.7, 12.8, 43.0 and 9.9%, respectively . Crude protein in forage grasses cultured with A was slightly higher than those with B, but the crude fiber was slightly lower. Crude ash was significantly higher in A. |
