摘要
近年来,我国农业机械化种植技术得到了广泛地推广和应用。研究评价了机械播种是否对玉米的主要农艺性状和产量构成因子产生影响,并筛选适合在广西壮族自治区(简称广西)实施机械播种的玉米品种。结果表明,当播种密度5.4万株/hm^(2)时,理论产量达到8887.5kg/hm^(2);每穴播种2粒种子相比于1粒种子,显著提高了出苗率并降低了漏播率。此外,产量测定结果表明,桂单162和青青700两品种更适合进行机械播种。
In recent years,mechanized agricultural production in China has been widely promoted and applied.Whether mechanical sowing has an impact on main agronomic traits and yield components of corn was evaluated,and corn varieties suitable for mechanical sowing in Guangxi was selected.Research results showed that when planting density was 54000 plants/hm^(2),theoretical yield reached the highest level of 8887.5 kg/hm^(2).Planting 2 seeds per hole significantly increased emergence rate and reduced missed sowing rate compared to planting 1 seed per hole.In addition,yield determination results showed that varieties‘Guidan 162’and‘Qingqing 700’were more suitable for mechanical sowing.
