Abstract [Objective] The research aimed to provide scientific basis for the application and popularization of new silage and forage maize varieties in Hainan Province. [Method] The adaptability test on six domestic special silage maize varieties and 3 varieties of forage maize was conducted to study their adaptability and feeding value in Hainan. [Result] The biological characteristics, yield and nutritional quality of all test varieties had obvious differences. Xinsiyu 14 and Guiqingchu 1 planted in spring, summer and autumn had higher yield, better nutritional quality, higher feeding value and strong adaptability. Yucao 4 could be planted in spring and used as forage. [Conclusion] Xinsiyu 14, Guiqingchu 1 and Yucao 4 had higher yield and better comprehensive characteristics, so it was suitable to be popularized.

近年来,随着农业产业结构的调整,海南省牛、羊养殖业发展较快,其养殖方式已向集约化、规模化方向发展,对青贮青饲饲料的需求越来越大。青贮是贮存和开发饲料资源、发展“节粮型”畜牧业的有效手段[1],在国内外的畜牧业生产中青贮饲料已得到广泛应用。可作为青贮饲料的饲草种类很多,其中青贮玉米是最重要的一种,具有较高的能量和良好的吸收率, 是目前奶牛、肉牛的最佳青饲料[2]。青贮玉米既可用作青饲料直接喂养反刍动物, 又可入窖青贮发酵备用, 非常灵活方便, 其营养物质可保存很长一段时间。……
