黑龙江省从1960年开始試驗研究氨水的肥效和施用技术,1965年在生产上进行了大面积示范,結果証明,氨水增产效果較高,是一种好肥料。为了充分发揮氨水的增产效果,提高作物产量,使之在新的生产高潮中发揮作用,現以1965年的大面积生产示范和所內試驗为主,把氨水在几种主要大田作物上的增产作用和使用方法簡介如下: Since 1960, Heilongjiang Province has experimentally studied the fertilizer efficiency and application technology of ammonia, and conducted a large-scale demonstration in production in 1965. The result proves that ammonia has a higher stimulation effect and is a good fertilizer. In order to give full play to the effect of increasing ammonia production, increase crop yield and make it play a role in the new production climax, we are now using large-scale production demonstration and in-house tests in 1965. Ammonia is applied to several major field crops The role of production and use of a brief introduction is as follows:
