摘要
为探明优质、耐密的玉米品种辽单1211的适宜种植密度,于2023年在辽宁省阜新市阜蒙县阜新镇,以辽单1211玉米为试验品种,设置了6.0、6.75、7.50、8.25万株/hm^(2)共4个密度水平,并研究分析了种植密度对辽单1211玉米产量和农艺性状的影响。结果表明,辽单1211玉米的产量随着种植密度的增加而提高,8.25万株/hm^(2)时达到最高产量,为11 065.00 kg/hm^(2);产量与种植密度成显著正相关关系,与穗长和百粒质量成极显著负相关关系,与茎粗成显著负相关关系。
In order to find out the suitable planting density of Liaodan 1211,a high quality and dense tolerant maize variety,four density levels of 60000,67500,75000 and 82500 plants/hm^(2) were set in Daguben Town,Fumeng County,Fuxin City,Liaoning Province in 2023.The effects of planting density on yield and agronomic traits of Liaodan 1211 maize were studied.The results showed that the yield of Liaodan 1211 increased with the increase of planting density,and reached the highest yield of 11065.00 kg/hm^(2) at 82500 plants/hm^(2);Yield was positively correlated with planting density,negatively correlated with panicle length and 100 grain mass,and negatively correlated with stem size.
