摘要
2010～2012年，通过玉米锌肥施用技术试验，重点研究了玉米施用锌肥的有效性及影响玉米锌肥效果的相关因素。结果表明：鲁北褐土化潮土上施用锌肥一般增产14．3％左右；以666．7m^2基施1．0～2．0 kg锌肥效果较佳，叶面喷施则以0．20％浓度硫酸锌效果最佳，喷施时期以苗期和拔节期施用效果较好，土壤有效锌含量在0．6 mg/kg以下时施用锌肥有稳定的增产效果。
The effectiveness of applying zinc fertilizer on summer maize and its relative influencing fac-tors were studied through field test during 2010~2012.The results showed that applying zinc in cinnamon tide soil of northern Shandong Province could generally increase corn yield by 14.3%;the effect of basic fertiliza-tion of zinc at 1.0~2.0 kg per 666.7m^2 was the best.For foliage spraying,0.20%zinc sulfate had the best effect,and applying at seedling and jointing stages could obtain better effect.When the soil available zinc content was below 0.6 mg/kg,the application of zinc fertilizer had stable yield increasing effect.
