摘要 玉米密植通透栽培技术是改善玉米田间通风透光条件,增加玉米密度的一项有效措施。采用正交试验的直观分析和方差分析,筛选出紧凑型品种江单1号;130 cm大垄双行株距20 cm,密度76 900株.hm-2;在施用有机肥22 500 kg.hm-2的基础上,施用化肥750 kg.hm-2(磷酸二铵360、硫酸钾150、尿素200、硫酸锌40 kg.hm-2,除尿素作追肥外,其余肥料均作种肥)为最佳组合,比其它处理增产极显著。 The ventilated and close planting cultivation technology of maize is an effective measure to improve the ventilation and transmitance condition in maize field and also to increase the density of maize planting.This experiment adopted the visual analysis and variance analysis based on orthogonal design.The optimum combination was compact cultivar named Jiangdan No.1,coupled with 130 cm long big ridge with plant space of 20 cm,of which the planting density was 76 900 plants·hm-2,and 750 kg·hm-2 fertilizer(Including 360 DAP,150 Potassium,200 urea,40 kg·hm-2 Zinc sulfate.Except urea used as additional fertilizer,others were used as seed fertilizer) based on the irrigating 22 500 kg·hm-2 of organic manure.
