摘　　要：S811南瓜耐干旱瘠薄,茎蔓性中空,叶互生肥大,果实圆形白色。南瓜杂交种需求量较大,因此南瓜制种在南瓜生产上较为重要。金塔县位于甘肃省河西走廊中西端,光照充足,降雨少,昼夜温差大,杂交制种具有得天独厚的优势。本文从选地、播种、管理、病虫害防治、杂交授粉、种子收获等几个关键环节入手介绍了S811南瓜品种在金塔县的杂交制种技术。S811 pumpkin is tolerant to drought and barrenness,with hollow stems,thick leaves and round white fruits. Pumpkin hybrid seeds are in great demand, so pumpkin seed production is more important in pumpkin production. Jinta county is located in the middle and western end of Hexi Corridor of Gansu province. It has abundant light, less rainfall and large temperature difference between day and night. Hybrid seed production has unique advantages. This paper introduced the hybrid seed production technology of S811 pumpkin varieties in Jinta county from the aspects of land selection, sowing, management, pest control, cross pollination, seed harvesting, and so on.
