液氨直接施肥是世界施肥技术史上的一项重大革新。近年来,兵团农一师建化厂、农科所、一团场,农六师一○二、一○三团场及塔里木农大等单位,在自治区液氨施肥协作组与化工局的指导支持下对该项技术进行了引进试点。实践证明:它在我新疆垦区适用可行并具有较大潜力。特别是目前尿素供应仍呈短缺与一些中小碳铵厂急待改产的情况下更有重要的现实意义。 一、液氨施肥的增产原理 液氨,又称合成氨(NH_3),是一种高浓度的液体化肥。它的含氮量高达82.3％,为尿素含氮量46％的1.8倍,为碳酸氢铵含氮量17％的4.9倍。它的沸点为-33℃ Direct application of liquid ammonia is a major innovation in the history of fertilization technology in the world. In recent years, Corps Nongyi Shi Jianhua Plant, Agricultural Science Institute, a group of field, the six farmers of 1022, 103 field and Tarot Farmers and other units in the autonomous region liquid ammonia fertilization collaboration with the guidance of the Bureau of Chemical Industry Under the introduction of the technology pilot. Practice has proved that: It is feasible and has great potential in our Xinjiang reclamation area. In particular, the current urea supply is still short of some small and medium-sized ammonium plants urgently need to change the case of more important practical significance. First, the liquid ammonia fertilization principle of liquid ammonia, also known as ammonia (NH_3), is a high concentration of liquid fertilizer. Its nitrogen content is as high as 82.3%, which is 1.8 times that of urea 46% and 4.9 times that of ammonium hydrogen carbonate 17%. Its boiling point is -33 ℃
