摘要
为了深入探究种植密度对玉米产量性状的影响,该研究设置了4.5万株/hm^(2)(T1)、6.0万株/hm^(2)(T2)、7.5万株/hm^(2)(T3)、9.0万株/hm^(2)(T4)以及10.5万株/hm^(2)(T5)等5个种植密度。并调查茎秆含水率、穗长、穗行数、百粒重等穗部性状。结果表明:在种植密度逐步提升的条件下,玉米的穗长、穗行数、行粒数以及百粒质量均呈现下降趋势,茎秆含水率呈先上升后下降趋势;‘MC278’在4.5万株/hm^(2)种植密度茎秆含水率及穗部性状表现最优。
In order to further explore the effect of planting density on maize yield traits,five planting densi-ties of 45,000 plants/hm^(2)(T1),60,000 plants/hm^(2)(T2),75,000 plants/hm^(2)(T3),90,000 plants/hm^(2)(T4),and 105,000 plants/hm^(2)(T5)were set up in this study.Ear traits such as stem moisture content,spike length,spike rows,and 100-grain weight were investigated.The results showed that:under the condition of increasing planting density,the ear length,the number of rows per ear,the number of grains in rows and the weight of 100 grains of maize showed a de-creasing trend,and the moisture content of stalks increased first and then decreased.MC278’had the best perfor-mance in stem moisture content and ear traits at the planting density of 45,000 plants/hm^(2).
