含硝态氮的国产化肥少了

我国生产的氮肥数量巨大,但含硝态氮的化肥所占比例很小,这不利于化肥的合理施用.铵态氮和硝态氮作为植物的氮源,两者基本上是等效的,要根据作物和土壤条件合理施用.我国应当适当增加含硝态氮化肥的生产.第一,要对硝酸铵进行改性,使之不能再制造炸药;第二,要消除认为用了硝态氮肥就不能生产绿色食品的错误认识.

The amount of Home-made nitrate N-containing fertilizers should be increased

The proportion of nitrate N-containing fertilizers in the total amount of nitrogen fertilizers is lower though a huge amount of nitrogen fertilizers is produced in China,which results in the unreasonable use for the chemical fertilizers.As the sources of plant nitrogen nutrition,both ammonium N and nitrate N have same effectiveness,based on the rational application of these two sources according to different crops and soil conditions.Production of nitrate N-containing fertilizers should be properly increased.Firstly,ammonium nitrate should be modified,so that it can not be to produce explosive.Secondarily,the misunderstanding that green food can not be produced with applying nitrate fertilizers should be cleared up.
