锌肥不同施用量对玉米产量及植株性状的影响

目的]探索江苏省新沂市黑岗土土壤类型上玉米锌肥不同施用量对玉米产量及植株性状的影响,为大面积推广玉米科学施肥提供科学依据。方法]通过田间小区对比试验,研究锌肥不同施用量对玉米产量及植株性状的影响。结果]锌肥能够促进玉米的生长发育,施用锌肥处理的玉米在产量及植株性状上均比对照处理明显增加。结论]玉米产量随锌肥施用量的增加呈先增加后降低趋势,当硫酸锌施用量为15.00 kg/hm~2时增产效果最显著,可比对照增产1 074.0 kg/hm~2,增产率达12.41%。

Effects of Application Amount of Zinc Fertilizer on the Yield and Plant Traits of Maize

Objective] To explore the effects of application amount of zinc fertilizer on the yield and plant traits of maize in black hill soil in Xinyi City, to provide scientific basis for large-scale scientific fertilization of corn. Method] Field plot comparative experiment was adopted to research the effects of application amount of zinc fertilizer on the yield and plant traits of maize. Result] Zinc fertilizer promoted the growth of maize.Maize after zinc fertilizer treatment showed significant increase in yield and plant traits, compared with the control. Conclusion] Maize yield firstly enhanced and then reduced as the zinc fertilizer increased.When the zinc sulfate was 15.00 kg/hm2 , yield increasing was the most significant, which enhanced by 1 074.0 kg/hm2 .And the increasing rate of yield reached 12.41%.
