为摸清新疆阿勒泰市常规施肥下春小麦作物氮、磷、钾的利用率现状,以及测土配方施肥提高氮肥、磷肥和钾肥利用率的效果,特开展田间氮、磷、钾的对比试验,结果表明:配方施肥全肥区产量及增产率高于常规施肥全肥区;配方施肥区氮、磷利用率最高,值得在大面积生产上推广应用。
In order to find out the status quo of nitrogen, phosphorus and potassium utilization of spring wheat under routine fertilization in Altay, Xinjiang and the effect of soil testing and formula fertilization to improve the utilization efficiency of nitrogen, phosphorus and potassium fertilizer, the comparative experiments of nitrogen, phosphorus and potassium in the field were carried out. The results showed that the yield and yield increase of fertilizer and fertilization were higher than that of conventional fertilization and fertilizer application. The nitrogen and phosphorus utilization rate of formula fertilization was the highest, which deserved to be popularized and applied in large-scale production.
