摘要: 【目的】根据内蒙古阴山北麓地区农业种植结构实际,探索不同轮作模式对马铃薯干物质积累、库活性及产量构成因素的影响,为减少马铃薯连作障碍、遴选适宜的轮作模式提供理论依据。【方法】试验设置4个处理,分别为绿肥作物春翻—绿肥作物夏翻—马铃薯、绿肥作物春翻—绿肥作物春翻—马铃薯、向日葵—向日葵—马铃薯、燕麦—向日葵—马铃薯,代码分别为LCLXM、LCLCM、XXM、YXM,对比分析不同轮作模式对马铃薯干物质积累、库活性及产量构成因素的影响。【结果】马铃薯各器官干物质积累速率、块茎最大干物质积累速率、干物质平均积累速率、干物质快速积累期持续时间均表现为LCLXM>LCLCM>YXM>XXM;马铃薯库活性则表现为LCLXM>LCLCM=YXM>XXM;LCLXM处理的马铃薯产量分别较YXM和XXM处理增加了10.54%和15.46%,LCLCM处理较XXM处理增加了12.20%,YXM处理的马铃薯干物质积累、库活性和产量均居中。【结论】综合考虑干物质积累、库活性和产量等各方面性状认为,适合内蒙古阴山北麓地区马铃薯种植的轮作模式为绿肥作物春翻—绿肥作物夏翻—马铃薯、绿肥作物春翻—绿肥作物春翻—马铃薯和燕麦—向日葵—马铃薯3种轮作模式。

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.
