科学施用氮肥不仅对农作物产量有所提高,而且会降低农业生产的成本,改善人类的居住环境,反之,不合理的施用氮肥除了对产量的增加起不到任何作用外,还会对环境造成大量的污染。在当前的农业生产中,存在氮肥施用量过大、单一的施用氮肥、裸施氮肥等不合理施用氮肥现象,针对不合理的施用氮肥现象,提出定量施肥、配合施肥、施用控释肥和配方肥等措施,从而减少氮肥的损失,降低生产成本,减少环境污染。
Scientific application of nitrogenous fertilizer will not only increase the crop yield, but also reduce the cost of agricultural production and improve the living environment of human beings. On the contrary, unreasonable application of nitrogenous fertilizer will have no effect on the increase of output, Pollution. In the current agricultural production, there is an excessive nitrogen fertilizer application, a single application of nitrogen fertilizer, nitrogen fertilizer and other unreasonable application of nitrogen fertilizer phenomenon, for irrational application of nitrogen fertilizer, proposed quantitative fertilization, with fertilization, the application of controlled release fertilizer and formula Fertilizer and other measures to reduce the loss of nitrogen fertilizer, reduce production costs and reduce environmental pollution.
