摘　　要：为了解引种巨菌草种植对生态和经济的影响,对会泽县4个乡镇5个村的6块种植巨菌草情况进行实地和访问调查。结果表明:该县具有代表性的种植地块包括3种类型39.33 hm 2。其中,由大户承包耕地种植15.66 hm 2,年产量180~315 t/hm 2,占种植面积的39.85%,全部作为大户养殖肉牛的饲料;田间地埂种植3.67 hm 2,年产量150 t/hm 2,占种植面积的9.3%,主要作为农户自己供养牛羊的饲草;中央草原生态恢复项目荒山荒坡种植20 hm 2,年产量105 t/hm 2,占种植面积的50.85%,主要是恢复生态,保持水土,防止草原退化。引种巨菌草种植带来畜牧业的发展和进一步加强生态环境的保护,为科学的种养殖业发展和生态环境的退化修复提供参考。In order to understand the ecological and economic impacts of introducing(Pennisetum giganteum z.x.lin),a field and interview survey was conducted on 6 plots of Pennisetum giganteum planted in 4 townships and 5 villages in Huize County.As a result,the representative planting plots in the county include three types of 39.33hm 2.Among them,15.66 hm 2 of farmland is contracted by large households for cultivation,with an annual output of 180~315t/hm 2,accounting for 39.85%of the planting area,all of which are used as feed for large households to raise beef cattle;Planting 3.67 hm 2 on field ridges with an annual yield of 150 t/hm 2,accounting for 9.3%of the planting area,is mainly used by farmers as their own feed for cattle and sheep;The Central Grassland Ecological Restoration Project cultivates 20 hectares of barren mountains and slopes,with an annual output of 105 t/hm 2,accounting for 50.85%of the planting area.The main purpose is to restore ecology,maintain soil and water,and prevent grassland degradation.The introduction of Pennisetum giganteum cultivation has brought about the development of animal husbandry and further strengthened the protection of the ecological environment,providing a reference for the scientific development of breeding and ecological grassland degradation and restoration.
