Abstract：The experiment was to investigate the effect of different periods of flat-cropping on growth and survival rate of Caragana korshinskii.The experiment took Caragana korshinskii of Siziwangqi in Ulanqab city as the research object and measured its nutrient composition every month between April and October.After two years of growth,the survival rate and related parameters of sprouting plants were evaluated.The results showed that the recovery rate of the average height of tillers was 38.15%in Caragana korshinskii after the flat-stupping in August.In April,136.92%of the average crown width of tillers were restored,which was suitable for flat stupping.In August and September,the average crown width of tillers was low,which was not suitable for flat stupping.In April,257.00 new branches were the most in Caragana korshinskii.The number of new branches was low in July.In April,the average fresh weight of new branches of Caragana korshinskii was 14.73%.The effect of flat stubble in July was the worst.The recovery ratio of the average diameter of tillers was 56.64%in June,which was lower in July and August.The study indicates that the survival rate of Caragana korshinskii is not reduced in different periods.
