为了给薏仁的高产优质栽培提供科学依据，采用裂区试验设计研究了种植密度及氮、磷、钾施用量对高秆白薏仁产量的影响。结果表明：在种植密度为1515～2083窝/667m2、纯N 0～18 kg/667m2、P 0～15 kg/667m2、K 0～18 kg/667m2，随着种植密度的增加，薏仁有效穗、千粒重增加，当种植密度为2083窝/667m2、纯N、P2 O5、K2 O施用量分别为9．0 kg/667m2、8．9 kg/667m2和11．9 kg/667m2时，薏仁的产量较高，为284．8 kg/667m2。因此，密度对薏仁产量有较大影响，氮、磷、钾3种营养元素缺乏或过量均会使薏仁产量大幅度降低。

In order to provide a scientific reference for high yield and high quality cultivation of Coix seed,a split plot experiment was conducted to study the effects of planting density and NPK fertilizers on yield of Coix seed.Results:The number of productive ear and thousand kernel weight increased with the planting density increasing under conditions of planting density 1 515~2 083 holes/667m2、pure N 0~18 kg/667m2 ,P 0~15 kg/667m2 and K 0~18 kg/667m2 .The yield of Coix seed reached 284.8 kg/667m2 under conditions of planting density 2 083 holes/667m2 ,pure N 9.0 kg/667m2 ,P 8.9 kg/667m2 and K 11.9 kg/667m2 .Consequently,planting density contributes more to the yield of Coix seed,the lack or excessive amount of NPK fertilizers may cause significant reduction of Coix seed yield.
