摘  要:
运用裂区设计法,对遵义市主推玉米(Zea mays L.)新品种的密度试验效果进行了比较分析。结果表明,种植密度从3 174株/667 m2增加到4 140株/667 m2,10个参试品种的产量均有所增加,其中B5(中单808)的产量增加最多,为178.59 kg/667 m2,增幅也是最大的,为39.27%;而增产最少的是B9(裕玉207),为75.30 kg/667 m2,其增幅也是最小的,为14.39%。综合分析结果表明,适当增加种植密度是提高遵义市玉米产量的有效途径。

摘  要:
The split block design was used to analyze the result of density experiment of new maize varieties in Zunyi city.Result indicated that when density increased from 3 174 plants/667 m2 to 4 140 plants/667 m2,all the 10 varieties in the experiment showed yield increase. Zhongdan 808 had the biggest yield increase of 178.59 kg /667 m2,with the highist relative increase of 39.27%. Yuyu 207 had the smallest yield increase of 75.30 kg/667 m2,with the lowest relative increase of 14.39%.Comprehensive analysis revealed that appropriate increase in density is an effective way of increasing maize yield in Zunyi city.
