一性状硫硝酸铵是硫酸铵与硝酸铵的混合物,其比例为硫酸铵占64%,硝酸铵占36%。其含氮量为26%,其中四分之一为硝酸態氮,四分之三为氨態氮。所以是一种氮素化学肥料,呈淡黄色,成小粒状。易溶解于水,稍有吸湿性。二施用硫硝酸铵做基肥或追肥都可。但它是速效性肥料,奏效快,所以最好是以农家肥料做基肥,用硫硝 A trait of ammonium sulfate is a mixture of ammonium sulfate and ammonium nitrate, the proportion of 64% ammonium sulfate, ammonium nitrate accounted for 36%. The nitrogen content of 26%, of which one quarter of nitrate nitrogen, three quarters of ammonia nitrogen. So it is a nitrogen chemical fertilizer, pale yellow, into a small granular. Soluble in water, slightly hygroscopic. Second, the use of ammonium sulphate to do basal or top dressing can be. But it is quick-acting fertilizer, effective, so it is best to do a base fertilizer with peasant farming, with sulfur nitrate
