补充资料：钾肥
| 钾肥 potash fertilizer 具有钾（K或K2O)标明量的单元肥料。能提高土壤供钾能力和植物的钾营养水平。根据钾肥的化学组成可分为含氯钾肥和不含氯钾肥。所有的钾盐肥料均为水溶性，但也含有某些其他不溶性成分。主要钾肥品种有氯化钾、硫酸钾、钾石盐、钾镁盐、光卤石、硝酸钾、窑灰钾肥。钾肥的施用除取决于土壤的供钾能力外，还受作物种类、农业生产水平和气候及土壤条件等因素的影响。土壤中钾的含量、形态及其转化和供钾能力是合理分配和施用钾肥的重要依据。土壤的全钾含量变幅较大 ，一般为0.1％～3％，平均约为1％。土壤中的钾包括3种形态：①矿物钾。主要存在于土壤粗粒部分，约占全钾的90％左右，植物极难吸收。②缓效性钾。约占全钾的2％～8％，是土壤速放钾的给源。③速效性钾。指吸附于土壤胶体表面的代换性钾和土壤溶液中的钾离子。植物主要是吸收土壤溶液中的钾离子。当季植物的钾营养水平主要决定于土壤速效钾的含量。一般速效性钾含量仅占全钾的0.1％～2％，其含量除受耕作、施肥等影响外，还受土壤缓放性钾贮量和转化速率的控制。 |
