摘  要：
试验于2010年6～9月在中国农业科学院草原研究所农牧交错区试验示范基地的混播人工草地上进行。试验分为划区轮牧组和连续放牧组,轮牧组与连续放牧组各设3个重复,轮牧区每个重复各有5个小区,每个小区放牧时间为6d。试验结果显示,不同放牧制度对各组草地牧草的干物质产量影响不显著;对各组草地牧草的营养物质影响差异显著(P<0.05);划区轮牧组牧草的粗蛋白质(CP)含量有高于同期连续放牧草地牧草的趋势,而中性洗涤纤维(NDF)含量低于连续放牧草地的牧草;对绵羊增重影响组间差异不显著。

摘  要：
This experiment was carried out in the artificial pasture on grassland demonstration pastoral area of Grassland Research Institute of Chinese Academy of Agricultural Sciences during June to September in 2010.The experiment was designed as rotational grazing group and continuous grazing group,there were three treatments in both rotational grazing group and continuous grazing group,there were 5 rotational grazing areas in every rotational grazing treatment,rotational grazing period was 30 days.The results showed that the effect of different grazing system on pasture dry matter yield was not significant;and that the effect of different grazing system on the nutrition of forage grass was significant(P<0.05).The crude protein content of the forage grass in rotational grazing group was higher than that in continuous grazing group,while the NDF content in rotational grazing group was lower than that in continuous grazing group.There were no significant differences in weight gain of sheep between rotational grazing group and continuous grazing group.
