采用田间试验的方法,对玉米养分吸收规律及优化配方施肥技术进行研究。结果表明,在玉米中,处理N2P2K2在籽粒养分吸收量上综合来看最为理想。玉米籽粒中氮素的累积量受氮、磷、钾化肥的施用的影响相对较大。磷素的累积受氮、钾肥施用的影响较大,而钾的累积受施肥影响较小。
Field experiments were conducted to study the law of nutrient uptake in maize and the optimization of fertilization technology. The results showed that in corn, N2P2K2 treatment of grain nutrient uptake in the most comprehensive point of view. The accumulation of nitrogen in maize grains was relatively affected by the application of nitrogen, phosphorus and potassium fertilizers. The accumulation of phosphorus was more affected by the application of nitrogen and potassium, while the accumulation of potassium was less affected by fertilization.
