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 quantity of nitrogen fertilizer produced in our country is huge, but the proportion of fertilizer containing nitrate nitrogen is very small, which is unfavorable to the rational application of fertilizers. Ammonium and nitrate As nitrogen sources for plants, the two are essentially equivalent and should be rationally applied according to crop and soil conditions. China should appropriately increase the production of nitrate-containing nitric fertilizer. First, ammonium nitrate should be modified so that it can no longer make explosives. Second, it is necessary to eliminate the misconception that it can not produce green food with nitrate nitrogen fertilizer.
