摘　　要：【目的】探究内蒙古土默川平原区工业大麻氮磷钾合理施肥量,提高工业大麻籽实产量。【方法】试验采用随机区组设计,设CK(不施肥)、N_(1)PK、N_(2)PK、N_(3)PK、NP、PK和NK 7个处理,分析不同施肥处理对工业大麻产量的影响,并计算氮磷钾肥料利用率,同时将氮肥用量与工业大麻产量进行一元二次回归线性拟合。【结果】N3PK处理(施氮量337.5 kg/hm^(2))工业大麻产量最高,为5676.95 kg/hm^(2),其次是N2PK处理(施氮量225.0 kg/hm^(2)),产量为5533.61 kg/hm^(2),较CK分别提高29.51%和26.24%;施用氮、磷、钾肥的产量反应分别为700.35~733.70、33.35~100.05、266.80~300.15 kg/hm^(2),施用氮、磷、钾肥农学效率分别为9.34~9.78、0.44~1.33、3.56~4.00 kg/kg,施肥的增产效果为氮肥>钾肥>磷肥;一元二次回归线性拟合结果表明,氮肥用量为274.84~320.88 kg/hm^(2)时可获得较高产量,为5574.38~5800.76 kg/hm^(2)。【结论】内蒙古土默川平原区工业大麻合理施肥参考值为氮肥用量274.84~320.88 kg/hm^(2)时,可获得5574.38~5800.76 kg/hm^(2)的较高产量。【Objective】To investigate the optimal NPK fertilizer utilization rates for industrial cannabis(Cannabis sativa L.)on the Tumechuan plain in Inner Mongolia,aiming to increase seed yield.【Methods】The effects of fertilizer treatments on the yield of industrial cannabis were conducted with a randomized block design,with CK(control without any fertilizer),N_(1)PK,N_(2)PK,N_(3)PK,NP,PK and NK seven treatments.The NPK fertilizer utilization rates were calculated.A univariate quadratic regression linear model was used to fit the amount of nitrogen fertilizer utilized and the yield of industrial cannabis.【Results】The maximum yield of industrial cannabis was 5676.95 kg/hm^(2) in the N_(3)PK treatment(nitrogen application rate 337.5 kg/hm^(2)).Followed by the N_(2)PK treatment(nitrogen application rate 225.0 kg/hm^(2))with a yield of 5533.61 kg/hm^(2).These were 29.51%and 26.24%higher than CK,respectively.The yield responses of nitrogen,phosphorus and potassium fertilizer were 700.35-733.70,33.35-100.05 and 266.80-300.15 kg/hm^(2) respectively.The agronomic efficiency of nitrogen,phosphorus and potassium fertilizer were 9.34-9.78,0.44-1.33 and 3.56-4.00 kg/kg respectively.Fertilizers had the following effect on yield:nitrogen fertilizer>potassium fertilizer>phosphorus fertilizer.The univariate quadratic regression linear fitting results showed that the yield was 5574.38-5800.76 kg/hm^(2) when the amount of nitrogen fertilizer was 274.84-320.88 kg/hm^(2).【Conclusion】The yield was 5574.38-5800.76 kg/hm^(2) when the nitrogen application rate was 274.84-320.88 kg/hm^(2) on industrial cannabis in the Tumechuan plain in Inner Mongolia.
