在垄膜沟灌、单蔓整枝栽培条件下对引进的15个厚皮甜瓜新品种进行了品比试验。结果表明，黄金7号品质好，抗逆性适中，折合产量最高，较当地主栽品种西州蜜25 增产38.94%；甘甜120次之，折合产量较西州蜜25增产21.15%，抗逆性强。这2个品种均为中熟品种，经济潜力大；银峰和都蜜橙5号抗逆性强、品质好，折合产量分别较西州蜜25增产11.06%、6.25%，属晚熟品种；翠蜜品质好，抗逆性适中，折合产量较西州蜜25增产1.44%，生育期较西州蜜25短20 d，有较强的价格优势。上述5个甜瓜品种综合表现优于当地主栽品种西州蜜25，可作为露地垄膜沟灌栽培的品种在民勤推广。

15 new introduced varieties of muskmelon， growing under the conditions of ridge film furrow irrigation and single vine pruning， were tested and analyzed. The results showed that Huangjin No. 7 had good quality and moderate stress resistance and the highest yield， which was 38.94% higher than Xizhou mi No. 25 (control). Ranking second to Sweet 120， the yield increased by 21.15% compared with the control. In addition， the two varieties were medium mature varieties with great economic potential；Yinfeng and Dumicheng No. 5 were late maturing varieties， owning the characteristic of strong stress resistance and good quality. Their yield increased by 11.06% and 6.25% than that of the control， respectively； Cuimi had good quality and moderate stress resistance. Its yield was 1.44% higher than that of the control， and its growth period was 20 days earlier than that of the control， advancing in commodity price as well. The comprehensive performance of the above five melon varieties is especially better than that of the control， which could be popularized as the varieties of open ridge film furrow irrigation in Minqin county.
