液氨(NH_3)含N82.3％,是气体氨的液化形态,系氮肥工厂的中间产品。尿素、硝氨、碳氨、氨水是它的再加工产物。液氨直接施肥,即液氨不再加工成固体化肥,直接作为氮肥施用。这样,工厂可省去氨的加工工艺,能源消耗可降低20—30％,避免了氨的加工损失(15—20％),生产成本可降低30％左右。因此,液氨在售价上,比等氮量的固体氮肥低30％以上。 液氨直接施肥,是现代农业在施肥技术上的一项重大改革。在国外是一项成熟的技术,我国目前还处于小规模试验示范阶段,但已引起了各方面的关注。此项技术的推广,对于我国到2000年实现总产值翻两番,

Liquid ammonia (NH3) containing N82.3%, is the liquefied form of ammonia gas, nitrogen plant intermediate products. Urea, ammonia, ammonia, ammonia is its re-processed products. Direct liquid ammonia fertilizer, liquid ammonia is no longer processed into solid fertilizers, as nitrogen fertilizer directly. In this way, the factory can save ammonia processing technology, energy consumption can be reduced by 20-30%, to avoid ammonia processing losses (15-20%), the production cost can be reduced by 30%. As a result, liquid ammonia is 30% lower in price than a solid nitrogen fertilizer with equivalent nitrogen content. Direct application of liquid ammonia is a major reform of modern agricultural fertilization technology. It is a mature technology in foreign countries. At present, China is still in the pilot phase of small-scale experiments, but it has drawn all kinds of concerns. The promotion of this technology, for our country to quadruple the total output value by 2000,
