通过氮、磷、钾肥料的单因素量级试验,可以掌握各个施肥单元不同作物优化施肥数量,基、追肥分配比例、施肥时期和施肥方法为施肥分区和肥料配方提供依据。此试验结果表明以施纯氮14.0kg/667m2、五氧化二磷6.0kg、氧化钾10.0kg配合施用有机肥每400kg/667m2的处理667m2产量表现最高,为每8180.4kg/667m2。
Through the single factor test of nitrogen, phosphorus and potassium fertilizers, we can know the optimal fertilization amount, base and top dressing allocation ratio, fertilization period and fertilization method for different fertilization units to provide the basis for fertilizer division and fertilizer formula. The results of this experiment showed that the yield of 667m2 per kg 400kg / 667m2 combined application of 14.0kg / 667m2 of pure nitrogen, 6.0kg of phosphorus pentoxide and 10.0kg of potassium oxide had the highest yield of 8180.4kg / 667m2.
