| 摘 要： | 试验观察了不同氮磷和肥料长效剂NAM及锌、锰肥配比对制种玉米产量的影响,结果表明:当氮、磷比为1:0.5,将N 300 kg/hm2、P2O5 150 kg/hm2、锌肥(含ZnSO4 96%)15 kg/hm2、锰肥(含MnSO4 96%)30 kg/hm2、肥料长效剂NAM 9 kg/hm2一次性做底肥施入时,制种玉米的穗长、穗粗、行数及行粒数明显增加,产量较不施肥增产152.5%,较常规施肥增产18.1%,可在大田玉米制种中推广应用。

| Abstract: | The trial to study the effect of different ratio of NP,the long effective preparation of NAM,zinc fertilizer as well as manganese fertilizer on the yield of producing corn seed with the multiple random block design.The results showed that 300 kg/hm2 pure nitrogen,150 kg/hm2 pure phosphorus,zinc fertilizer 15 kg/hm2,manganese fertilizer 30 kg/hm2 and the long effective preparation of NAM as base fertilizer could improve obviously ear length,ear diameter,rows and row grains,which increased the yield to 9 034.... |
