不同时期喷施不同配方叶面肥对绿豆产量及主要性状的影响

Effects of Spraying Foliar Fertilizer with Different Formulations at Different Periods on Yield and Main Characters of Mung Bean

喷施叶面肥是促进绿豆增产的有效方法之一。除了氮、磷、钾之外,微量元素对绿豆的生长和产量也十分必要。本试验旨在筛选出促进绿豆生长,提高绿豆产量的最佳喷施叶面肥的时期和配方,在苗期、分枝期、现蕾期和开花期分别喷施清水(CK)、金典+中华大肥旺+天赐宝、金典+中华大肥旺+天赐宝+碧护、金典+中华大肥旺+天赐宝+碧护+EM活菌剂,结果显示:在盛花期喷施金典+中华大肥旺+天赐宝+碧护增产效果较好,可酌情添加EM活菌剂。

Spraying foliar fertilizer is one of effective methods to increase mung bean yield. Trace elements are also necessary for the growth and yield of mung bean except for nitrogen, phosphorus and potassium. The purpose of this experiment is to screen the best spraying period and formulation of foliar fertilizer to promote the growth and increase the yield of mung bean. Water(CK),“Jindian + Zhonghuadafeiwang + Tiancibao”,“Jindian + Zhonghuadafeiwang + Tiancibao + Bihu”,“Jindian + Zhonghuadafeiwang + Tiancibao + Bihu + EM”were sprayed on leaves of mung bean in seedling stage, branching stage, squaring stage and flowering period, respectively. The result showed that spraying“Jindian + Zhonghuadafeiwang + Tiancibao + Bihu”made mung bean a higher yield, EM can be added as needed.
