| 摘 要： | 为明确东北不同地区春玉米光合特性、产量构成与产量的关系,在内蒙古通辽、吉林九台、吉林龙潭和吉林二道进行区域比较试验,测定其叶面积指数、产量及产量构成等指标。结果表明,春玉米产量表现为内蒙古通辽>吉林二道>吉林九台>吉林龙谭。对产量性能与产量的相关分析表明,平均叶面积指数(MLAI)和千粒重与产量呈极显著正相关,这说明平均叶面积指数是影响东北地区春玉米产量提高的关键因素。 |

| Abstract: | In order to clarify the relationship between spring maize photosynthetic characteristics,yield components and yield in different ecological areas of the Northeast China,regional comparative tests in Tongliao,Jiutai,Longtan and Erdao were undertaken.Leaf area index,yield,yield components and other indicators were measured.The results showed that the performance order of spring maize production was Tongliao,Erdao,Jiutai and Longtan.Correlation analysis was performed according to yield performance and yield,in... |
