摘要
为研究种植行距对玉米干物质积累量和产量的影响,设置等行距60 cm(M1)、等行距70 cm(M2)、宽窄行50 cm+70 cm(M3)、宽窄行40 cm+80 cm(M4),研究玉米干物质积累量、转运参数和产量及产量构成因素的变化特征。结果表明,不同行距处理间的玉米物质积累和产量存在显著的差异,其中以宽窄行40 cm+80 cm处理的玉米干物质积累量最高,花后转运效率和花后干物质贡献率最高,玉米产量最高,达到10080.05 kg/hm^(2),显著高于其他处理。因此,在单县夏玉米种植采用40 cm+80 cm的种植行距具有较好的生产效益。
To study the effects of planting row spacing on dry matter accumulation and yield of maize,four treatments were set up:60 cm equal row spacing(M1),70 cm equal row spacing(M2),50 cm+70 cm widenarrow row spacing(M3),40 cm+80 cm wide-narrow row spacing(M4).The changes in dry matter accumulation,transport parameters,yield and yield components of maize were studied.The results showed that there were significant differences in maize dry matter accumulation and yield among different row spacing treatments.Among them,the 40 cm+80 cm wide-narrow row spacing treatment had the highest dry matter accumulation,the highest post-anthesis transport efficiency and post-anthesis dry matter contribution rate,and the highest maize yield,reaching 10080.05 kg/hm^(2),which was significantly higher than other treatments.Therefore,the planting row spacing of 40 cm+80 cm has better production efficiency in summer maize planting in Shan County.
