三元化肥是一种含有氮、磷、钾的复(混)合肥料。在毛主席“独立自主、自力更生”伟大方针指引下,我国自己设计、制造的三元化肥,经山东、河南等烟区广泛应用,表现出良好效果。一、改进烟叶品质烟草施用化肥的一个突出问题是,品质欠佳,烟味辣呛,而施用国产三元化肥的烟草,质量显著提高。经三年连续试验,以及有关部门和贫下中农的评吸鉴定,一致反映,施用国产三元化肥的烟味,较施用进口复合肥料者好得多,而与施用饼肥的烟味相近似。 Ternary fertilizer is a complex containing nitrogen, phosphorus and potassium (mixed) Hefei material. Under Chairman Mao’s guiding principle of “independence and self-reliance,” our country’s own design and manufacture of ternary fertilizers has been widely used in such tobacco-growing areas as Shandong and Henan and has shown good results. First, to improve the quality of tobacco Tobacco application of a prominent problem is that the fertilizer, poor quality, tobacco smoke spicy choking, and the application of domesticated three yuan fertilizer tobacco, significantly improve the quality. After three years of continuous testing and assessment of appraisals by the relevant departments and poor and under-middle peasants, it was unanimously reflected that the smoke smell of domesticated ternary chemical fertilizers was much better than that of imported compound fertilizers and similar to that of the cake-coated fertilizer.
