摘要??选用高淀粉玉米品种鑫鑫一号为试材，通过不同施肥方式的调节，测定玉米产量和根区土壤酶活性，确定齐齐哈尔地区的高淀粉玉米栽培施肥方式。结果表明，处理S1玉米小区产量显著高于其他3个处理（P0.05）;土壤脲酶活性苗期和拔节期处理T1显著高于其他处理（P0.05），成熟期处理S1显著高于其他3个处理（P0.05）;土壤过氧化氢酶活总体呈下降趋势，但成熟期处理T1土壤过氧化氢酶活性反而升高，显著高于其他处理（P0.05）。土壤脱氢酶活性处理T1显著高于其他各处理（P

目前，玉米由單纯产量向定向品质型、专用型转变，实现高产、优质、专用是现代玉米发展的趋势[1]。而在高淀粉玉米生产上采用传统施
