摘　　要：为探寻中量元素叶面肥在韭菜上施用的适宜浓度,采用田间试验方法研究不同浓度(T1:5 m L·L^(-1),T2:8 m L·L^(-1),T3:10 m L·L^(-1))中量元素叶面肥对韭菜生长发育及产量的影响。结果表明,当中量元素叶面肥浓度为8 m L·L^(-1)时,韭菜产量、生长指标、根系活力及光合色素含量都明显增加,并达到最大值。随着中量元素叶面肥浓度的增加,韭菜的产量呈先增后降的趋势。In order to explore the appropriate concentration of mid-elements foliar-fertilizer spraying on Chinese chives,the effect of different concentrations of foliar-fertilizer on growth and yield of Chinese chives was analyzed. The yield, growth index, root activity and photosynthetic pigment content were increased to be maximized when the concentration of the foliar-fertilizer is 8 mL-L-1. However, with the increasing of foliar--fertilizer concentration, the yield of Chinese chives firstly increased and then decreased.
