摘　　要：为明确缓控释肥料在鲜食糯玉米生产中的合理用量,采用田间试验方法,研究了缓控释肥料施用量对鲜食糯玉米的植株性状及产量的影响。结果表明:缓控释肥料施用量为300~900kg·hm^(-2)时,鲜食糯玉米的叶片数、株高、穗位高、茎粗、穗长、穗粒数和产量均随施用量的增加而增加,并未表现出抑制作用。In order to clear the reasonable amounts of slow controlled release fertilizer in the production of fresh waxy maize.The effect of slow controlled release fertilizer amounts on plant characteristic and yield of fresh waxy maize was researched by cultivating in field.The result showed that the amount of slow controlled release fertilizer was in the range of 300~900kg·hm^-2,the number of leaves,plant height,ear height,stem diameter,ear length,grain number per ear and yield of fresh waxy maize were gradually increased with the increase of fertilizer amount,and were not suppressed by slow controlled release fertilizer.
