Abstract：In order to study the effects of different cultivation modes on yield and economic benefits of potato production after winter rapeseed harvest in the Loess Plateau of eastern Gansu province,a single factor experimental area design was adopted in this experiment.The original potato seed variety Longshu No.7 was used as experimental material,and a total of 8 cultivation modes were designed.They are plain cropping,plain cropping and ridge raising,high ridge black film mulching,high ridge white film mulching,high ridge black film mulching,high ridge white film cover soil,high ridge white film cover soil,straw strip mulching and ridge furrow rain collection.Through the comparision of potato agronomic characters,commodity rate,yield and economic benefits under different patterns,the best cultivation mode of winter rape stubble multiple planting potato was selected.The results showed that the three cultivation modes of straw strip mulching,flat planting and ridge and furrow planting were better,and the yield of 667 m2 was 2 292.81,1 917.63 and 1 655.46 kg,respectively,which increased 41.27%,18.15%and 2.00%compared with the control(plain cropping),respectively.
