摘要
采用"3414"试验设计,探索花生间作大豆条件下氮磷钾配施效应,经过肥料效应函数拟合,研究了氮磷钾肥不同比例配合施用对花生、大豆产量的影响。结果表明:花生各施肥处理较不施肥处理增产21.48%～45.84%,大豆增产23.67%～63.32%,综合肥料效应函数分析表明花生间作大豆高产推荐施肥量(kg.hm-2)为:N166.39、P2O5224.91、K2O 125.45,即N∶P2O5∶K2O=1.33∶1.79∶1。
＂3414＂ fertilizer experiment design was adopted to investigate the optimum ratio of nitrogen,phosphorus and potassium fertilizer on yield of peanut intercropping soybean.Results showed the yield of peanut and soybean could be improved by 21.48%～45.84% and 23.67%～63.32% under different fertilizer combination,and the dosage of 166.39,224.91,125.45 kg·hm-2 for N,P2O5 and K2O（N∶P2O5∶K2O=1.33∶1.79∶1）was the optimum fertilizer combination for yield of peanut intercropping soybean.
