不同耕作方式对黑河地区玉米产量及其性状的影响

摘要

立足于高纬度地区采用的耕作方式,通过2009年和2010年在黑河地区的平作定点试验,比较常规垄作、灭茬平作和留茬平作3种不同玉米茬口处理方式对玉米产量和其性状的影响。结果表明：由于黑河地区气候具有特殊性,灭茬平作和留茬平作在该地区均无明显的增产效果。%Based on the farming of high latitudes,through the designated test,the maize yield and characters of maize affected by conventional culture and skimming stubble and leave stubbly of flat planting three different crop methods in 2009 and 2010 in Heihe area were compared.The results showed that skimming stubble of flat planting and leave stubbly of flat planting had no obvious effect on yield increasing due to the particularity climate of Heihe region.
