摘要
利用中早熟品种济宁202,于垄作小麦收获后在垄上直播夏玉米,研究了垄作栽培对夏玉米生长发育的影响。结果表明:与传统平作栽培相比,垄作栽培的夏玉米根系发达,茎基部节间缩短,穗位高及其相邻节间变长,株高降低,叶面积系数前期增长快,后期下降慢,叶面积高值持续期长,干物质积累快,生物产量高,穗粒数多,百粒重高,产量性状明显优于传统平作,增产显著。
Study was conducted to the effect of sowing in hills after wheat on growth, development and yield components of summer maize with Jining 202. The results were that the comparison to conventional flat planting, the summer maize planted on ridge was with shorter basal internode and longer internodes with ear, above ear and below ear, the height of plant was shorter than that with conventional flat planting, the LAI of the maize increased faster than that of the maize of conventional flat planting in early stage, and the later decreased faster than the former in late stage, so the maize on ridge with higher LAI kept a relative longer period, sowing in hills improved yield components and increased grain yield greatly.
