摘　　要：为实现黑龙江省玉米可持续发展和提高玉米产量,试验研究了不同耕作方式对玉米产量及农艺性状的影响。结果表明,各处理间产量差异达到极显著水平(p<0.01),其中免耕平作(T1)产量最高,产量为10 088.5kg/hm2,穗数为秋翻平作(T2)>免耕平作(T1)>秋翻垄作(T3),穗粒数、百粒重、穗粒重、穗长为T1>T2>T3。各处理的棒3叶叶面积差异极显著,大小依次为T1>T2>T3;各处理株高、穗位高以及茎粗大小依次为T1>T2>T3,但处理间各指标差异不显著。In order to realize the continuable development and increase the yield of corn in Heilongjiang province,we study the effects of different tillage patterns on corn yield and agricultural traits with the meth-od of random test design.The results showed that the yield difference among the three treatments was signif-icant（p〈0.01）,the yield of corn under T1 was highest,10088.5kg/hm2,the number of corn ears per square meter was T2〉T1〉T3.The grain number per ear,100-seed weight,the grain weight per ear and ear length were T1〉T2〉T3.The leaf area of three ear leaves were T1〉T2〉T3,the three treatments was sig-nificantly different.The plant height,ear position and the stem diameter were T1〉T2〉T3,but the differ-ence among the three treatments was not significant.
