摘　　要：盆栽试验条件下,研究氮、磷、钾肥不同用量对光叶紫花苕子(Vicia villosa Roth var.glabrescensKoch.)生长发育及生物量的影响。结果表明,施用氮肥和钾肥对苕子生物量及相关农艺性状影响不显著,施磷肥显著提高苕子株高、叶片大小、叶绿素含量以及产草量。与不施磷肥相比,施磷可使苕子盛花期干物质量增加1.28～2.38倍。The effects of the application of nitrogen,phosphorus and potassium fertilizer on the growth,development and yield of smooth vetch were studied by pot experiment.The results showed that the influences of the application of nitrogen and potassium fertilizer on the growth and yield of smooth vetch were not significant.The plant height,leaf size,chlorophyll content and yield of smooth vetch were observably improved by the application of phosphorus fertilizer.Compared to the treatment without phosphorus fertilizer,the yield of smooth vetch was increased 1.28～2.38 times by the application of phosphorus fertilizer.It was suggested that the phosphorus fertilizer should be highlighted in the process of growth of smooth vetch growth.
