摘要
为确定昌图县花生最佳施肥量,采用"3414"试验,研究氮、磷、钾肥对花生生长性状及产量的影响。结果表明:少施或缺施肥料对花生的长势和产量有不同程度的影响;合理的氮、磷、钾配比可明显促进花生生长。在中等肥力情况下,最佳施肥量为N5.0kg/667m2,P2O54.0kg/667m2,K2O3.5kg/667m2。
In the paper, the influence on the growing characters of peanut of different NPK levels was studied through ＂3414＂ test. The result showed rational proportion of NPK can obviously stimulate the growth of peanuts and the optimum ffertilization amount is N 5 kg/ 667 m2, P2O5 4 kg/667 mE, K2O 3.51 kg/667m2.
