近年来世界各国对氨水氮肥的生产和应用,都有显著的增加,苏联和波兰正在广泛地发展氨水的生产。根据我国各地的试验资料认为化学肥料以氮肥增产最显著,所以氮肥需要量也最多。目前我国生产的氮肥以硫酸铵为主,生产硫酸铵需要消耗大量的硫酸,而生产氨水不用硫酸,大大降低生产成本,因此氨水的生产和使用,党和政府极为重视,1959年8月和12月
In recent years, the production and application of ammonia nitrogen fertilizer have been significantly increased in all countries in the world, and the production of ammonia water is being widely developed in the Soviet Union and Poland. According to the test data around our country that chemical fertilizers to increase the most significant nitrogen fertilizer, nitrogen fertilizer needs are also the most. At present, the nitrogenous fertilizer produced in our country is mainly ammonium sulfate. The production of ammonium sulfate consumes a large amount of sulfuric acid, and the production of ammonia does not use sulfuric acid, greatly reducing the production cost. Therefore, the production and use of ammonia water attach great importance to the party and the government. In August 1959 and December 12 month
