【摘要】 为探究等带宽条件下玉米/秋马铃薯不同间作行比对秋季马铃薯生长及遮阴效果的影响，筛选出适合中原二作区特别是鲁西南地区推广应用的玉米/秋马铃薯间作模式，设计T1（玉米/秋马铃薯=1/1）、T2（玉米/秋马铃薯=1/2）、T3（玉米/秋马铃薯=1/3）、T4（玉米/秋马铃薯=1/4）、T5（玉米/秋马铃薯=2/2）、T6（玉米/秋马铃薯=2/3）、T7（玉米/秋马铃薯=2/4）共7个处理，分析比较不同行比间作下马铃薯生长环境、形态特征、产量的变化。结果表明：在各处理中，T2处理较T5处理产量显著增加9.74%，增产效果明显；马铃薯的株高随着玉米/秋马铃薯行比的减小而减小；各处理的土壤含水量的差异不显著；T2处理较T7处理的日均土壤温度显著降低8.9%，日温差显著降低46.7%。综合分析，针对中原二作区特别是鲁西南地区玉米与秋马铃薯等带宽间作模式，1行玉米间作2行秋马铃薯的间作模式更有利于秋马铃薯的生长。更多还原

【Abstract】 To explore the effects of different row ratios in maize/autumn potato intercropping on the growth of autumn potato in the central double cropping system zone. this experiment set up seven row ratios: T1(maize/potato = 1/1), T2(maize/potato =1/2),T3(maize/potato=1/3), T4(maize/potato=1/4), T5(maize/potato=2/2), T6(maize/potato=2/3) and T7(maize/potato=2/4). The morphological characteristics and yield of potato and edaphic condition under different row ratios were analyzed and compared. The results showed that T2 increased the yield compared to other treatments; The plant height of potato decreased with the decrease of the row ratio. There was no significant difference in soil moisture content among the treatments; The daily soil temperature in T2 was reduced8.9% and the daily temperature reduced 46.7% compared to T7. Based on comprehensive analysis, one row of maize and two rows of autumn potato(maize/potato=1/2) is more implementary with respect to the growth of autumn potato in Shandong province, especially in the southwest part.更多还原
