摘　　要：马铃薯大垄栽培方式具有提高块茎产量、改善土壤理化性质及耕层结构等优点,为明确80 cm垄宽条件下不同播种深度对马铃薯产量的影响,以马铃薯品种‘费乌瑞它’与‘克新18号’为材料,2014~2015年研究了8个不同播种深度下马铃薯产量的差异。‘费乌瑞它’总产量和商品薯产量年度和播种深度互作效应极显著,在降水较多的2014年处理地表上10 cm总产量最高,而在降水相对较少的2015年处理地表上0 cm总产量则最高;商品薯产量在年份间对播种深度的反应与总产量相似。和‘费乌瑞它’不同,‘克新18号’总产量和商品薯产量年度和处理互作效应均不显著,处理地表上5 cm无论总产量还是商品薯产量均最高。播种深度在地表上0 cm至地表上10 cm时绿薯率与烂薯率均较低。The big ridge cultivation for potato has the advantages of improving potato tuber yield,soil physical andchemical properties and plow layer structure.In order to understand the influence of seed pieces planted in80cm ridge atvarious planting depths on potato yield,eight treatments of planting depth of two potato varieties('Favorita'and'Kexin18')were investigated for their yield performance in2014and2015.Year and planting depth interaction of the total andmarketable tuber yields for the variety'Favorita'was highly significant.The treatment of seed piece planted at10cm aboveground gave the highest total yield in the wet year of2014,while the treatment of seed piece planted at0cm above groundhad the highest total yield in the relative dry year of2015.The marketable tuber yield had similar trend as the total yield inthe two years.In contrary to'Favorita','Kexin18'was not significant for the total and marketable tuber yield in terms of yearand planting depth interaction.The treatment of seed piece planted at5cm above ground yielded well in both total andmarketable tuber yield.The percentages of green tuber and rotten tuber were low when seed pieces were planted at therange of0-10cm above ground.
