【摘要】 该研究紧密结合宁夏中部地区草原的实际,系统地开展了不同放牧方式下草地植物特性、草地植物群落结构、牧草生物学与生态学特性及放牧家畜的生产性能等方面的研究。结果表明:实行6区的划区轮牧方式是科学利用该类草地的最佳方式。轮牧比对照草地生产力提高73.84%。羊只体重轮牧组分别比对照(传统舍饲)、连续放牧和季节放牧组提高4.7kg、0.35kg和1.6kg。更多还原

【Abstract】 Closly combining with the fact of grassland in Ningxia middle region,the characteristics and structures of grassland plant community,biological and ecological characteristics of forage and growth performance of grazed livestock were studied regularly by different grazing methods.The results showed that rotational grazing method of six areas was the best.Compared with natural grassland,the productivity of rotational grazing increased 73.84%;the living weight of ewes in rotational grazing was 4.7kg,0.35kg,1.6kg more than that of traditional grazing,continuous grazing and seasonal grazing,respectively.更多还原
