Abstract: 【Objective】To explore the effects of potato different rotation patterns on dry matter accumulating, reservoir activity and provide a theoretical basis based on the actual agricultural planting structure in the northern foothills of Yinshan Mountain, Inner Mongolia.【Methods】The effects of different rotation patterns on potato dry matter accumulation and reservoir activity were analyzed in 4 treatments of green manure spring turn-green manure summer turn-potato(LCLXM), green manure spring turn-green manure spring turn-potato(LCLCM), sunflower-sunflower-potato(XXM), oat- sunflower-potato(YXM).【Results】The results showed that the dry matter accumulation rate of potato organs, the maximum dry matter accumulation rate of tubers, the average dry matter accumulation rate and the duration of the rapid dry matter accumulation period were all shown as LCLXM>LCLCM>YXM>XXM; potato reservoir activity shown as LCLXM>LCLCM=YXM>XXM;the output of LCLXM was significantly increased by 10.54% and 15.46% compared with YXM and XXM, respectively, and the output of LCLCM was significantly increased by 12.20% compared with the output of XXM, and YXM was in the middle for the dry matter accumulation, reservoir activity, and yield.【Conclusion】The suitable rotation patterns for potato cultivation in the northern foothills of Yinshan, Inner Mongolia, were green manure spring turn-green manure summer turn-potato, green manure spring turn-green manure spring turn-potato and oat - sunflower-potato rotation by considering the dry matter accumulation, reservoir activity and yield in potato.
