中文摘要	通过田间小区试验,研究了不同施肥对春小麦籽粒、秸杆和根系养分的吸收状况及产量的影响.结果表明,与对照(CK)相比,科学合理施肥不但在一定程度上增加了春小麦N、P、K养分含量,而且大幅度的增加了春小麦的产量,以化肥氮磷钾(NPK)处理的效果最为显著,其氮、磷、钾素的总吸收量分别增加了156.9%、94.4%和112.8%,氮、磷、钾的养分收获指数最大分别是0.730、0.778和0.130.增施化肥及有机肥均能促进春小麦产量的增加,增产幅度为32.8%～214.2%,其中氮肥的增产效果最为明显,以化肥氮磷钾(NPK)配施处理最优,在促进作物氮、磷、钾养分浓度的提高及产量的增加效果上最为明显.
英文摘要	In this paper, the effect of absorption and yield in grain, straw, root of spring wheat under different fertilization were studied by field plot experiment. The results showed that, Scientific and rational use of fertilization not only increased spring wheat yield, but also increased N、P and K con-tent in spring wheat to some extent, Which compared with control. The treatment of NPK is most significant, the total uptake of nitrogen, phosphorus and potassium increased respectively by 156. 9%, 94. 4% and 112. 8%, The maximum of nutrient index of nitrogen, phosphorus and potassium is respectively 0. 730, 0. 778, 0. 130. Applying organic manure and chemical fertilizer could increase spring wheat yield, The output increased by 32. 8%～214. 2%, the effect of Nitrogen fertilizer in-creasing production is obvious. Combined application of nitrogen, phosphorus and potassium has best effect, has significantly effect on increasing crop N, P and K content and yield.
