摘要
以早熟玉米新品种边单3号为试验材料,应用3种植物生长调节剂单一及其复合制剂对边单3号玉米进行拌种处理,研究了不同植物生长调节剂对玉米产量和产量主要构成因子的影响。结果表明:不同的植物生长调节剂单一及复合制剂均可提高玉米产量,明显改善玉米的穗部性状,在V5(a+c)处理时玉米的穗部性状表现最好,产量也最高,为9 935.71kg.hm-2,与各处理间差异均达到了极显著水平。研究认为复合处理效果明显好于单一处理,而a、c两种调节剂的复合制剂对玉米进行拌种效果最佳。
Taking extremely early maturing maize variety Biandan No.3 as test material,single and composite of three kinds of plant growth regulators were used to dress seed,the effects of the different plant growth regulators on maize yield and yield components were studied.The results showed that：different plant growth regulator of single and compound formulations could improve the yield of maize,significant improvement in the maize ear traits,the best performance of ear traits were in the treatment of V5（a＋c）,which with the highest yield for 9 935.71 kg·hm-2,extremely significantly different with the other treatments.The study suggested that the effect of combined treatment was significantly better than a single process,while a mixed c compound regulator worked best for maize seed dressing.
