摘要
[目的]进一步研究玉米最佳施锌量,为肥料配方、科学施锌及提高玉米产量提供科学依据。[方法]采取小区试验设计,共4个施锌水平,5个处理。[结果]在当地习惯施肥的基础上,施用不同量微量元素肥料硫酸锌,玉米生长稳健,根系发达,综合抗性增强,籽粒饱满,提高了玉米的结实率和粒重,有效改善了玉米的成产因素,增产效果明显。[结论]结合蒙城土壤有效锌含量状况,对缺锌土壤基施硫酸锌22.5 kg/hm2较适宜。
[ Objective ] The experiment aimed to further study the optimum amount of zinc in maize, which provided scientific basis for the for- mulafion of fertilizer, the scientific application of zinc and the improvement of corn yield. [ Method ] Experiments were carried out to design a plot of 4 levels of zinc and 5 treatments. [ Result ] Based on the local custom of fertilization, after the application of different quantities of trace element fertilizer of zinc sulfate, the growth of corn was stable and the root system was developed, comprehensive resistance was enhanced, grain yield and grain weight were increased, the yield of maize was improved, and the yield of maize was significantly improved. [ Conclusion] Com- bined with the contents of soil available zinc in Mengcheng, the application of zinc sulfate 22.5 kg/hm2 is more appropriate.
