我国无氯钾肥生产现状与市场需求

Production situation and market demand of chloride-free potash fertilizer in our country

无氯钾肥是不含氯的钾肥,忌氯作物需要施用无氯钾肥。我国目前生产的无氯钾肥主要有硫酸钾、硝酸钾、磷酸二氢钾、偏磷酸钾、硫酸钾镁、窑灰钾肥、硅钾肥,年总生产不足50万t K2O。随着农产品结构调整与高效农业发展,无氯钾肥市场需求潜力巨大,年需求量至少在100万t K2O以上。

Chloride-free means fertilizer without chlorine ,which is specifically used for crops that are sensitive to chlorine. The annual production of chloride-free potash fertilizer is less than 50 000 t （K2O） ,including potassium sulphate, potassium nitrate ,potassium dihydrogen phosphate, potassium metaphosphate, magnesium potassium sul- phate ,cement flue dust ,silicon-potassium fertilizer. With the structure readjusting of farm product and development of agriculture ,the potentiality of market demand for chloride-free potash fertilizer is great and the annual demand is probably more than 100 000 t（K2O）.
