In order to explore the feasibility of deep vertically rotary tillage on potato yield and quality in the Glue river area of Shandong province,rotary tillage and deep vertically rotary tillage were designed in this study.Effects of soil physical properties,root biomass,tuber productivity were investigated.Results showed that compared with rotary tillage,deep vertically rotary tillage broke plough pan,significantly reduced soil density and penetration resistance at 20~40 cm layers and soil water storage increased by 25.67% within 50 cm layers.It was beneficial to plant growth and improved root biomass of deep vertically rotary tillage by 2661%,increased net photosynthetic rate in the middle and lower leaves by 20.82% and 3713%,promoted dry matter accumulation after flowering,and then significantly increased dry matter accumulation and contribution of translocation of dry matter stored in tuber after flowering.In general,a single weight of potato under deep vertically rotary tillage treatment increased by 29.82% and tuber yield increased by 38.68%.
