[目的]探究不同营养供给对玉米产量的影响。[方法]以玉米品种郑单958为试验材料,研究以不同方式供给营养对玉米产量的影响。[结果]结果表明,在底施基肥的基础上,分别以种肥拌种、根外追肥、加施菌肥的方式给玉米供养,玉米长势强壮,玉米地面茎节数不变、茎节变粗、穗位降低,穗长增长,穗行数、行粒数略有增加,凸尖减少,果穗变粗,穗重、穗粒重、出米率、百粒重比对照提高显著,增产效果明显,尤以种肥、根外追肥、增施菌肥并用增产更为突出。[结论]在底施基肥基础上,菌肥、拌种肥、液体肥料的配合使用,可以明显提高玉米产量。
[Objective] The research aimed to investigate the effects of different nutrient supply on corn yield. [Method] The maize variety Zhengdan 958 was used as the experimental material to study the effects of supplying nutrition in different ways on the yield of maize. [Result] The results showed that on the base of basal application of basal fertilizer, the maize was supplied with seed dressing, root top dressing and fertilizer application respectively. The maize grew vigorously. Rooting, panicle weight, grain weight per spike, grain yield per spike, grain weight per 100 grains increased significantly compared with the control, and the yield was increased Obviously, especially in a kind of fertilizer, root top dressing, increase fertilizer and increase production more prominent. [Conclusion] Based on the basal application of base fertilizer, the combined use of bacterial fertilizer, seed dressing fertilizer and liquid fertilizer could obviously increase the yield of maize.
