摘要
对影响牧草再生性的诸因素进行了分析,阐明了牧草再生性对刈割和放牧利用方式的响应,以及刈割和放牧后牧草体内贮藏的碳水化合物和氮素在再生中的变化规律及作用,为草地的放牧利用和刈割提供了理论和技术依据。
Factors which effect Forage Regrowth were analyzed,and The developments of the studies of the forage regrowth was analyzed.The influence of forage regrowth factors was analyzed.Tthe influence of cutting regime and grazing mode on forage regrowth was describedillustrated,and.Variation of carbohydrate reserve and nitrogen in forage regrowth underaffter cutting and grazing on forage regrowth physiology was elucidated.The views provided theory and technique for grassland cutting production and grazing utilization as well.
