杂交玉米新品种兴海201抗逆丰产栽培技术

Resistant and High-Yield Cultivation of New Hybrid Maize Variety Xinghai 201

杂交玉米兴海201是黔西南州农业科学研究所于1999年组配而成的黄粒玉米单交种,该品种全生育期127 d左右,高产、优质、适应性广、抗逆性较强、稳定性较好,适宜贵州、云南及湖北恩施等山区相同生态特点的地区种植。研究主要围绕抗旱播种和避免伏旱及如何实现中低产田旱坡地增产等几个方面展开,详细阐述了适时早播以避伏旱、玉米营养球培育壮苗、增加群体密度、平衡施肥、病虫鼠综合防治保产保优、适时收获等获得高产的关键技术要点,以指导杂交玉米兴海201大田生产。

An interline hybrid maize variety Xinghai 201 was bred by Qianxinan Institute of Agricultural Sciences in 1999.Xinghai 201 showed perfect plant type,high yield,strong resistance to diseases, good trait stability and growth period of by 127 d,which adapts to mountainous areas such as Guizhou,Yunnan and Enshi in Hubei. This paper discusses the drought resistant sowing pattern, the prediction of summer drought for higher yield in mid- and low-yielding farmland and arid hillside areas, and the technical key including early sowing in time,corn nutrition ball seeding,increasing population density, balancing fertilization and so on in order to promste large-field production of Xinghai 201.
