摘　　要：济薯26是山东省农业科学院作物研究所育成的优质高产食用型甘薯新品种,为提升该品种的增产潜力进而加快推广,特就耕地深度、化学防治地下害虫、植物生长调节剂控制旺长三项措施对济薯26产量和品质的影响进行研究。结果表明,旋耕深度25 cm;栽插时穴施5%毒死蜱颗粒剂60.0 kg/hm^2;栽插后50天喷施5%烯效唑3 000 g/hm^2,且每隔5 d喷施1次,连喷3次,甘薯的产量最高、品质最佳。Sweet potato cv. Jishu 26 was bred by Crop Research Institute,Shandong Academy of Agricultural Sciences. It is a new fresh edible variety with high quality and high yield. To promote the yield-increasing potential and accelerate popularization,the effects of three cultivation techniques on the yield and quality of Jishu 26 were studied including plowing depth,chemical control of insect pests and plant growth regulator to control vigorous growth. The results showed that the best dispose was plowing depth as 25 cm,hole fertilizing 5% chlorpyrifos granule for 60. 0 kg / hm^2 when transplanting,and spraying 5% uniconazole for 3. 0kg / hm^2 after transplanted for 50 days（ once every 5 days and spraying 3 times continuously）. Under these conditions,Jishu 26 could obtain the highest yield and the best quality.
