摘　　要：[目的]研究不同种植模式对玉米产量和农艺性状的影响。[方法]以当地3个不同类型的主栽玉米品种为试验材料,设3种不同种植模式,采用裂区设计,共9个处理,3次重复,观察记录其农艺性状并测定产量。[结果]3个不同类型玉米品种的农艺性状均以单行双株种植模式最佳;平展型品种正大999单行单株种植的产量最高,单行双株种植的产量次之;半紧凑型品种正大619和紧凑型品种玉美头105单行双株种植模式的产量最高。[结论]平展型玉米品种适合于单行单株或单行双株种植;半紧凑型品种和紧凑型品种适合于单行双株种植。结合生产实际考虑,建议在轻简栽培中,玉米采用单行双株种植模式。[ Objective ] To study the effects of different planting patterns on yield and agronomic traits of maize. [ Method ] With three different plant types of local maize varieties as experimental materials, under three different planting patterns, a total of nine treatments were set by split block design with three replications to observe and record the yield and agronomic traits. [ Results] For agronomic traits of the three different plant types of maize varieties, singlie-line double-seedling planting pattern was the best . For flat type maize variety Zhengda 999, single-line single-seedling planting pattern achieved the highest yield, followed by singlie-line double-seedling planting pattern. For semi-compact varietyZhengdaS19 and compact variety Yumeitou 105, singlie-line double-seedling planting pattern presented the highest yield. [Conclu- sion ] Flat type maize varieties are suitable for singlie-line double-seedling planting pattern or single-line single-seedling planting pattern, semicompact varieties and compact varieties are suitable for singlie-line double-seedling planting pattern. Combined with production practice, singlie-line double-seedling planting pattern is the better way for light and simple cultivation of maize.
