摘要
为探究西辽河平原地区春玉米高产高效栽培模式,本试验以农华101和伟科702为试材,在7.5万株/hm^2种植密度下,以常规种植(CK)为对照,研究宽行种植(KH)模式对春玉米叶面积、干物质及产量的影响.研究结果表明,宽行种植模式下,春玉米叶面积下降缓慢,生育后期单株叶面积显著高于对照,完熟期差异最大,分别较对照高32.26%(农华101)和31.43%(伟科702);干物质积累能力较强,生育后期单株干物质显著高于对照,完熟期差异最大,分别较对照高2.63%(农华101)和2.89%(伟科702);实测产量显著高于对照,分别较对照高7.81%(农华101)和5.56%(伟科702).可见,宽行种植可作为西辽河平原地区春玉米高产栽培模式之一.
The effects of wide row planting mode（KH）on spring maize were compared to the conventional cultivation（CK）（control）in the West Liaohe plain. Spring maize cultivars 101 Nong Hua and 702 Wei Ke were planted at a density of 75 thousand plants/hm^2. Growth parameters measured were leaf area,dry matter and yield.The leaf area decreased slowly, but the leaf area per plant was significantly higher in the wide row planting than that of control at late growth stage and the mature period exhibited the biggest difference.The wide row planting mode was 32.36% higher in 101 Nong Hua and 31.43% in（702 Wei Ke than that of the control. The ability of dry matter accumulation was strongerand and the dry matter per plant was significantly higher in stage in wide row plantingthan that of control at late growth and at maturity.The wide row planting was 2.63% higher in 101 Nong Hua and 2.89% higher in 702 Wei Ke than that of control.The yield of wide row planting mode was 7.81% higher in 101 Nong Hua and 5.56% higher in 702 Wei Ke compared to the control.The wide row planting can be used as one of spring maizehigh yield cultivation mode in West Liaohe plains.
