在无水浇条件下，进行沟麦套种甘薯旱作高产栽培技术试验，实现了每公顷产粮１５ｔ的目标。３年度小麦、甘薯（折干）两季平均单产达１５６００ｋｇ／ｈｍ２～１９４５９．５ｋｇ／ｈｍ２，比平播小麦——夏甘薯一年两季增产２１８１．０ｋｇ／ｈｍ２～６０４０．５ｋｇ／ｈｍ２，增长１６．３％～４５％；沟麦套甘薯高产栽培技术要点：施足肥料；选用抗旱抗病高产的小麦甘薯良种；小麦适期播种，甘薯适当早套，并盖地膜；小麦基本苗１８０万株／ｈｍ２～２２５万株／ｈｍ２，甘薯６０００株／ｈｍ２左右。
Under the condition of no water pouring, the high-yielding cultivation experiment on sweet potato with interplanting furrows and mulches was conducted, achieving the goal of 15t per hectare of grain yield. The yield of wheat and sweet potato in three years reached 15600kg / hm2 ~ 19459.5kg / hm2 in two seasons, which increased 2181.0kg / hm2 ~ 6040.5kg / hm2 16.3% ~ 45%; ditch wheat sets of sweet potato high yield cultivation techniques: Shi enough fertilizer; selection of drought-resistant high-yielding wheat sweet potato varieties; sowing wheat suitable, sweet potatoes suitable early set, and cover film; Plant / hm2 ~ 2.25 million / hm2, sweet potato about 6,000 / hm2.
