摘要
采用"3414"施肥方案,通过大田试验研究了不同N、P、K配比与用量及喷施硼肥对花椒产量的影响。结果表明:N、P、K配合施用能明显提高花椒产量,其中配方6施肥效果最好,单株产量较对照提高88.4%。喷施硼肥可以增加花椒产量,较不喷肥产量平均提高4.07%。根据肥料效应模型,氮(N)、磷(P2O5)、钾(K2O)施用量分别为254、1761、16 g.株-1时产量最高。
Field trial was conducted to study the effect of N, P, and K balanced fertilization on the production of Zanthoxylum bungeanum Maxim with the ＂3414＂ fertilizer application scheme. Meanwhile a split- plot study on the effect of spraying boron on the production of Z. bungeanum. The results showed that the mixture of N, P , and K could increase the production significantly. Yield per plant with the formula 6 （N ： P ： K=150 ： 120 ： 120） increased by 88.4% and 88. 6% compared to the control（no fertilization）. Foliar spraying boron also could increase the yield by 4.07% compare to the control（no spraying）. In conclusion, the best nitrogen, potassium and phosphorus applied amount to every plant was 254 g, 176 g, and 116 g to get high production.
