以春播花生为试验对象,进行“3414”肥料试验,研究不同氮磷钾配比肥料施用量对产量的影响。试验结果表明:在本试验条件下分别对氮、磷、钾进行肥料效应方程拟合分析,得出氮肥最佳推荐量为在13.5 kg/667 m2基础上适当增加施肥量;磷肥最佳推荐量为8.5 kg/667 m2;钾肥最佳推荐量为10.4 kg/667 m2,在实际生产中和不同种植条件下可以对施肥量进行适当调整。
With spring sowing peanut as test object, “3414” fertilizer experiment was carried out to study the effects of different NPK fertilizers on yield. The results showed that under the test conditions, the fitting analysis of the fertilizer effect equation of nitrogen, phosphorus and potassium respectively showed that the best recommended amount of nitrogen fertilizer was the appropriate amount of fertilization on the basis of 13.5 kg / 667 m2; Is 8.5 kg / 667 m2. The best recommended amount of potash fertilizer is 10.4 kg / 667 m2. Fertilizers can be properly adjusted in actual production and under different planting conditions.
