摘　　要：以"永甜十一"薄皮甜瓜品种为试材,研究了萌蔓式留二茬瓜方式对甜瓜坐果性状及产量的影响。结果表明:在开花时即留基部萌蔓,其萌蔓率较高,5d后萌蔓率达76.6%;头茬瓜沾花时、坐果时及坐果后7d基部留蔓的头茬瓜膨大速度相近;坐果后7d基部留蔓的单株坐果率最高,为54.8%,头茬瓜沾花时基部留蔓的单株优果率最高,为81.4%;总产量以一茬瓜收获前10d,在原瓜秧处补种的处理最高,667m2产量5 198.7kg;头茬瓜沾花时基部留蔓的总收入最高,667m2收入56 877.0元,比对照667m2增收18 089.7元,可见,各种留蔓处理方式收入差异较大的原因是由于二茬瓜收获时期早晚的价格差异引起的。Taking ＇ Yongtianshiyi＇ thin-peel Cuxlumis rnelo L. as material, the effect of sprout gemination style to the second harvest on fruit-bearing character and yield were studied. The results showed that the sprouting rate was very high when preserved sprout at basal part at anthesis, reached 76.6% after 5 days;It was similar in the speed of enlargement from the first harvest during floral dip and fruit setting after fruit setting 7 d,fruit setting rate reached 54. 8% when preserved sprout after fruit setting 7 days. Excellent fruit rate was the highest reached 81.4% when reseeding at former seedling before harvest ten days^total yield reached 5 198. 7 kg/667m2. Preserved sprout at basal part at flower dipping period in first harvest had the highest income, reached 56 877. 0 yuan/667m2, increase about 18 089. 7 yuan/667m2 compared to CK. Income differences at different sprout germination came from the price of different second harvest time.
