摘　　要：为明确微量元素锌对玉米穗粒性状和产量的影响,以金科968为材料进行大田试验,设置不施用锌肥、习惯施肥、推荐施肥结合锌肥不同含量喷施、底施9个处理,调查玉米生育期及其产量的变化。结果表明,施用锌肥玉米产量有一定提高,产量增幅为2.41%~15.81%,玉米植株长势好,叶色深绿,玉米果穗较长,在一定程度上减少了秃顶。The objective of the current research was to determine the influence of the trace element zinc on the characters of maize ear and grain and its yield.Using the maize cultivar ’Jinke 968’ as the experimental material,a field trial was carried out to investigate the growth periods and yields of maize in nine treatments including no application of zinc fertilizer,conventional fertilization strategy,recommended fertilization strategy(application of a slow-release fertilizer),conventional fertilization strategy combined with spray or bottom application of a zinc fertilizer at different rates,and recommended fertilization strategy in combination with spray or bottom application of a zinc fertilizer at different rates.The results showed that the yield of maize increased by 2.41%~15.81% with the application of the zinc fertilizer.
