| 摘 要： | 通过对不同栽培方式及群体结构下,两个不同株型玉米的干物质积累动态及产量差异比较分析,结果表明大垄双行栽培,可以有效地改善玉米群体结构,减少株间竞争,促进个体生长发育,增加其干物质积累,提高玉米的产量。种植方式与密度之间存在明显互作效应,大垄双行栽培方式下紧凑型品种的适宜种植密度为6．00-6．75万株／hm2,平展型品种的种植密度为5．25-6.00万株／hm2,分别比对照小垄栽培增产19．09％和14．25％。

| Abstract: | Through dried matter accumulation trends of two different plant type maize and yield difference were comparatively analysis, under different cultivation way and community construction, result indicate that, the community construction was improved effectively, the competition among individuals were less, the growth of individuals were better, dried matter accumulation was increased, the yield of maize was improved There were obviously mutually effect among cultivation ways and density, appropriate density of compact corn was 6.00-6.75 ten thousand/hm2 under the way, planting density of unfold flat corn planting was 5.25-6.00 ten thousand / hm2 in double rows on a big ridge cultivation, yield was increased separately to 19.09% or 14.25% than contrast (on a little ridges cultivation). |
