采用盆栽试验研究氮磷钾配施对工业大麻品种云麻1号的生长、干物质和氮磷钾养分积累与分配的影响。氮是影响大麻生长和产量形成的主要因素；氮、钾供应充分时，磷的影响不显著；缺氮时，增施磷、钾肥对纤维产量形成的作用微弱；对比 NPK 和 NK 配施，NP 配施一定程度上阻碍了大麻的生长与干物质积累；NK 配施增加植株对氮钾的积累，但 PK 配施虽增加了植株对磷的积累，却减少了对钾的积累；大麻植株对钾积累最多，氮次之，磷最少。结果表明，氮磷钾三要素对大麻产量的贡献差异较大，三要素之间存在互惠和拮抗效应，从而影响大麻对它们的吸收与积累。

Effects of combined fertilization of nitrogen,phosphorus and potassium on growth and accumulation and distribution of dry matter and N,P,K nutrients in industrial hemp cultivar Yunnan hemp 1 were studied via pot culture.Nitrogen was the main factor determining the growth and yield, while the effect of phosphorus was not significant if nitrogen and potassium were enough.P and K fertiliz-ers affected the bast fiber yield little,if nitrogen was deficient.Being compared with NPK and NK,NP impeded the growth and dry matter accumulation.PK treatment promoted phosphorus accumulation but impeded potassium accumulation,while NK treatment facilitated the accumulation of both nitrogen and potassium.Hemp consumed potassium mostly,nitrogen secondly,phosphorus least.The results showed that NPK contributed differently to the growth and yield.There were mutual benefits and antagonistic ac-tion between the three elements,which affected the absorption and utilization of them in hemp.
