摘　　要：通过田间试验研究施肥量、栽培定植密度对产量的影响,结果表明,对洋葱鳞茎增长具有重要影响因素的是钾肥施用量,定植密度和氮肥施用量为次主要因素,磷肥施用量是次要因素。对产量具有主要影响因素的是氮肥施用量,定植密度和钾肥施用量为次主要因素,磷肥施用量是次要因素。经综合平衡法分析后,得出最优的栽培措施是A2B2C3D1。采用此栽培措施,洋葱产量最高。By field test on the effect of the amount that applied fertilizer and the culture density on the yield, the resuits indicated that the main factor influenced the growth of bulb of Allium cepa L. was fertilizer K, after that were culture density and the arrount that applied carbamide, and the amount of fertilizer P is less important, that the main factor influenced the yield was the amount of applying carbamide, after that were culture density and the amount applied fertilizer K, and the amount of fertilizer P was less important factor. By comprehensive balance analyzing, got that the best cultural measure was A2B2C3D1, and adopted the measure, the yield of Allium cepa L.was high.
