摘　　要：亚麻是北方旱区重要的油料作物。论文采用"3414"试验设计,研究了旱地亚麻N、P、K肥效应及适宜的肥料用量。结果表明,N、P、K配合施用显著提高了亚麻产量,三因素增产大小顺序为N>P>K;在该试验条件下,N、P_2O_5、K_2O用量分别为45.00、33.75、37.50 kg/hm^2时,N、P、K肥利用率最大,分别为8.38、11.85、14.93 kg/kg。一元二次肥料效应模型模拟结果显示,旱地亚麻N、P_2O_5和K_2O适宜施用量分别为41.85、82.95、37.50 kg/hm^2。Flax is an important oil crop in arid north of China.Based on the“3414”fertilizer experiment protocol,a field experiment was conducted to study the effects of NPK fertilizers and optimum fertilizer rate on dryland of flax.The results showed that the coordinated application of nitrogen,phosphorous and potassium significantly increased the yield of flax significantly,and the effect on the yield of flax could be ranked as N>P>K;the most effective combination utilized N 8.38 kg/kg、P 11.85 kg/kg、and K 14.93 kg/kg when it was applied N 45 kg/hm2、P2O5 33.75 kg/hm2 and K2O 37.5 kg/hm2 respectively.According to univariate quadratic model,the most appropriate fertilization for flax was N 41.85 kg/hm2、P2O5 82.95 kg/hm2、K2O 37.5 kg/hm2 respectively.
