硫铵也叫硫酸铵,是一种生理酸性肥料。由于它吸湿性小,含氮量高,深受群众欢迎。但在安排明年施肥计划时,请农户注意不要连年在一块地上大量地施用它。因为硫铵施入土壤后,分解为铵离子和硫酸根离子。作物对它们的吸收具有选择性,大部分铵离子很快被吸收了,剩下的硫酸根离子就会在土壤中积累。同时作物根系呼吸放出的二氧化碳,又与土壤中的水形成碳酸,碳酸会进一步分解为氢离子和碳酸根离子。其中氢离子与土壤中积累的硫酸根离子结合而成硫 Ammonium also known as ammonium sulfate, is a physiological acid fertilizer. Because of its hygroscopicity, high nitrogen content, welcomed by the masses. However, when planning next year’s fertilization plan, ask farmers not to use it on a large scale year after year. Because ammonium sulfate into the soil, the decomposition of ammonium ions and sulfate ions. Crops are selective for their absorption, and most ammonium ions are quickly absorbed and the remaining sulfate ions accumulate in the soil. At the same time crop roots breathe the release of carbon dioxide, but also with the water in the soil to form carbonic acid, carbonic acid will be further broken down into hydrogen ions and carbonate ions. Hydrogen ions in the soil and the accumulation of sulfate ions combine into sulfur
