摘要
以先玉335为试验材料,设宽行(WR)、宽窄行(SR)、高光效模式(HPE)、常规种植模式(CK)4个模式处理,测定不同种植模式农艺性状,研究种植模式对春玉米农艺性状的影响.结果表明:不同种植模式春玉米农艺性状均以宽行轻简种植模式(WR)、宽窄行种植模式(SR)优于常规种植模式(CK)和高光效种植模式(HPE).在高产地块,宽行轻简种植模式和宽窄行种植模式均可通过合理的行距布置,改善群体的通风透光条件和整体光合能力,增产能力较等行距模式和高光效模式明显,是适宜通辽地区推广的种植模式.
Different planting pattern effects on agronomic characteristics of spring maize Xianyu 335 in the Tongliao area were assessed. Treatments included wide row (WR), wide and narrow row (SR), high photosynthetic efficiency (HPE) and conventional spacing planting patterns (CK) 4. The results showed that wide row planting patterns (WR), wide and narrow row planting patterns (SR) are better than the conventional spacing (CK) and high photosynthetic efficiency patterns (HPE). In high-yield plot, WR and SR patterns can be spaced reasonably to improve conditions of ventilation and light and the overall photosynthetic capacity, increasing production capacity compared to equal row spacing and high efficiency model, which is suitable for planting mode application in the Tongliao area.
