摘要: 通过对4个青贮玉米进行高产栽培示范结果表明, 科多八号和科多四号初期生长较缓慢, 日生长量分别为3.51cm/d和3.18cm/d, 7月30日后生长加快, 日生长量达到4.66cm/d和5.36cm/d, 科青一号和英红玉米则正好相反;在4个品种和两个施肥处理中以科多四号和科多八号产量较高, 施肥为N37.5P225K225的处理中, 科多四产量最高, 达到143578.5 kg/hm2, 经济效益最好, 达到11486元/hm2, 4个品种的产量(114767.6~143578.5kg/hm2)均高于处理N37.5P225K150的产量(98814.0~120244.5kg/hm2);科多四号和科多八号叶量丰富, 茎叶比在1∶0.43~1∶0.52。
