【摘要】 探讨了不同基肥组合处理对退化坡地的改造利用和对牧草生产的影响．在相同的肥水管理条件下，以“鸡粪＋牛粪＋石灰”的基肥组合（Ａ）处理退化坡地土壤，可使皇草、杂交狼尾草、矮象草和墨西哥玉米的年产量比“猪粪＋牛粪＋石灰”的组合（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．更多还原

【Abstract】 Different combinations of base fertilizers were used in culture of several forage grasses on degraded sloping land. Treatments with base fertilizers were "l5 t hm~2 chicken dung + l5 t hm~2 cattle dung + 750 kg hm~2 lime" (combination A) and "l5 t hm~2 pig dung + l5 t hm~2 cattle dung +750 kg hm~2 lime" (combination B). The experiments showed that annual yields of Pennisetum purpureum× P. glaucum, Pennisetum glaucum×P purpureum, Pennisetum purpureum and Zea mays subsp. mexicana 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.更多还原
