Abstract
To clarify the regulatory effects of integrated drip irrigation and fertilization on sweet potato yield and quality,this study used the main sweet potato variety'Pushu 32'in Shen County,Shandong Province as the test material,and compared the effects of conventional water fertilizer management and drip fertigation treatment on sweet potato dry matter accumulation,yield,and quality.The results showed that the integration of drip irrigation and water fertilizer significantly promoted the accumulation of dry matter in'Pushu 32',and the dry weight of the aboveground and underground parts increased by 21.4％and 34.3％,respectively by the harvest period.In terms of yield,drip irrigation treatment significantly increased the average plant weight,plant weight,and number of tubers,with a total yield of 64 017.45 kg/hm2,an in-crease of 40.06％compared to conventional management.At the same time,the integration of drip irrigation and water fertilizer significantly improved the quality indicators of sweet potato,such as soluble sugar,starch,vitamin C,and protein.In summary,the integrated drip irrig-ation and water fertilizer technology has significant advantages in increasing yield and improving quality in the efficient cultivation of'Pushu 32'.It is recommended that this technology be promoted and applied in the Shen County based on local ecological conditions and tailored to local circumstances.This study can provide a theoretical basis and data support for the green and efficient production of sweet potatoes in the Shen County.关键词
