不同绵羊载畜率对短花针茅荒漠草原植物群落特征的影响
Influence of different sheep stocking rates on plant community features in Stipa breviflora desert steppe
【摘要】 采用分区放牧的方法,对不同载畜率处理短花针茅草原植物群落特征进行对比研究,目的是确定最适宜的载畜率。研究结果表明,过高的载畜率和过低的载畜率都不利于草地群落的正常演替,载畜率为1.8只/ha处理有助于维持草地生产力。
【Abstract】 Plant community features of Stipa breviflora desert stepper under different stocking rates were discussed with field sheep grazing in order to determine the proper stocking rate.The results shows that higher or lower stocking rate did not benefit to plant community succession and the proper stocking rate was 1.8sheep per hectare,which benefits the maintenance of grassland productivity.
