| 摘 要： | 选用热带主要牧草草种进行长期定位试验。结果表明，豆科牧草氮和钙的浓度显著高于禾 本科牧草。豆科牧草耗氮虽然比禾科牧草多，但由于豆科牧草具有固氮作用，因而对土壤全氮和有机质的消耗量却比禾本科牧草低。

| Abstract: | A long term trial had been carried out on tropical forages.The results indicated that the concentration of N and Ca in legume forages were greater than that of grass forages.Because of the nitrogen fixation of legumes,even though legume forages absobed more nitrogen than grass forages,the soil nitrogen and organic matter used by legume forages were less than grass forages. |
