我院农学系“小型轻便液氨施肥模型及其效果”科研成果鉴定已于1985年12月14日通过。这种液氨施肥模型比较适合我国田块面积较小的特点。液氨的含氮量为82%,是高含氮量氮素化肥,用试制的液氨施肥装置施肥,以稻、麦为指示作物,可获得与氯化铵、硫铵、尿素等周体氮素化肥等氮等效的结果。 Agronomy Department of our hospital, “a small portable liquid ammonia fertilization model and its effect” scientific research appraisal was passed on December 14, 1985. This liquid ammonia fertilization model is more suitable for our country plots smaller features. The nitrogen content of liquid ammonia is 82%, which is a nitrogenous fertilizer with high nitrogen content. Fertilizer is applied to the liquid ammonia fertilization device trial, rice and wheat are the indicated crops, and can be obtained with ammonium chloride, ammonium sulfate, urea and other perimeters Nitrogen fertilizer and other nitrogen equivalent results.
