摘要
[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 aim was to explore influence of different nutrient supply on corn yield. [Method] Taking the corn variety Zhengdan 958 as material, the influence of different nutrient supply on corn yield was studied. [Result] The results showed that the corn grew strong, and with unchanged ground internode number thicker internodes, decreased ear, growth ear length, a slight increase rows per ear and kernels per row, reduced spur, thicker ear, and the ear weight, grain weight, rice yield, kernel weight was significantly higher than the control, so increased the yield, by respectively seed dressing fertilizer, foliar application, gasch- fertilizer to corn dependent manner, on the basis of the bottom fertilizers. The yield was more prominent with treatment in conjunction with seed fertilizer, extraradieal topdressing fertilizer and adding bacterial fertilizer especially. [Conclusion] The treatment in conjunction with seed fertilizer, extraradieal topdressing fertilizer and adding bacterial fertilizer could significantly increased corn yield, based on the bottom fertilizers.
