为鉴选适于西辽河平原灌区的耐密高产玉米品种,2010年在通辽金山农业科技园区研究了在9.26万株hm-2的高密度种植条件下4个玉米品种（内单314、宁玉309、金山116和金山20）的生产性能.结果表明,产量以内单314最高,其次为宁玉309、金山116和金山20,其中,内单314、宁玉309和金山116产量、穗粒数和千粒重差异不显著,但三者均极显著高于金山20;不同品种间,叶面积指数和光合势在乳熟期至成熟期差异较大,均以宁玉309最高;吐丝后地上干物质积累量宁玉309明显高于其它3个品种;根系干物质积累量各生育时期均以宁玉309最大,且在吐丝期与其它品种间的差异最为明显.从产量结果来看,内单314、宁玉309和金山116是西辽河平原灌区密植高产的适宜品种.

In order to choose varieties of maize with high yield and high density-endurance suitable for the irrigation area of the plain of Xiliao river, the n production performance of four varieties of maize (Neidan314,Ningyu309,Jinshanll6 and Jinshan20) were studied under the 92600 plants hm-2high planting density in Jinshan agriculture science and technology zone in 2010. The results showed that, the yield of the Neidan314 varieties of maize was the highest, followed by Ningyu309,Jinshanll6 and 20.The yield,grain number and 1000-grain weight showed no significant differences on the Neidan314, Ningyu309 and Jinshanll6,which were significant higher than Jinshan20; There were great differences among diferent varieties in leaf area index and photosynthetic potential,and Ningyu309 was the highest.The ground dry matter accumulation of the Ningyu309 was significantly higher than the other three varieties after silking stage,and root dry matter accumulation of the Ningyu309 was the largest during growth periods,and was significantly different to the other varieties in silking stage . Seen from the yield of 4 varietise of maize, neidan314, NingYu309 and Jinshanll6 were suitable for high density plantiry in irrigation of area plain of Xiliao river.
