为了展示测土配方施肥效果,进一步校正施肥技术参数,优化肥料配方,我们在宜阳县小麦中产区进行了测土配方施肥田间肥效校正试验。结果表明:配方区较习惯区增产55.84千克/667平方米,增产率为13.68%;配方施肥区投入产出比为1∶7.58,习惯施肥区投入产出比为1∶7.08。肥料利用率氮肥提高17.69%、磷肥提高0.86%、钾肥提高49.88%。667平方米节本增效97.56元/667平方米。
In order to show the effectiveness of soil testing and fertilizer formula, fertilizer parameters to further correct fertilization, fertilizer formulations optimization, we Yiyang wheat mid-yielding field fertilizer application field fertilizer correction test. The results showed that the yield of reclaimed area was 55.84 kg / 667m2 and the rate of increase was 13.68%. The input-output ratio of reclaimed area was 1: 7.58. The input-output ratio of habitat area was 1: 7.08. Fertilizer utilization increased 17.69% nitrogen fertilizer, phosphate fertilizer increased 0.86%, potash increased 49.88%. 667 square meters cost-effective 97.56 yuan / 667 square meters.
