小麦的有机肥氮部分替代化肥氮试验研究

Experiment on Partial Replacement of Chemical Fertilizer Nitrogen by Organic Fertilizer Nitrogen Based onWheat

有机肥氮部分替代化肥氮在小麦上的试验结果表明,单施无机氮处理在小麦单位面积有效穗、穗粒数、籽粒产量等方面均优于单施有机氮和有机氮与无机氮配合施用处理。在综合考虑作物产量、经济效益和环境效益的前提下,结合本试验研究,以有机肥替代20%化肥施用可最大程度地减少小麦产量降低,增加氮肥利用率,减少环境污染。

The results showed that the effective panicle per unit area,grain number per panicle and grain yield of wheat treated with inorganic nitrogen alone were better than those treated with organic nitrogen alone and combined application of organic nitrogen and inorganic nitrogen.On the premise of comprehensive consideration of crop yield,economic benefits and environmental benefits,combined with this experimental study,the application of organic fertilizer instead of 20%chemical fertilizer can reduce the decrease of wheat yield to the greatest extent,increase nitrogen use efficiency and reduce environmental pollution.
