钾盐对农作物的增产有明显的效果。试验结果证明,每斤氧化钾可增产粮食2.8—7.2斤,薯类33.3斤,花生7.1斤,籽棉1.9斤,黄麻4.1斤。在氮肥、磷肥施用量日益增加,农作物亩产量不断提高的情况下,土壤中钾的储备消耗很大而将感不足。因此,努力寻找钾肥资源,为生产钾肥提供原料,是当前石油化工部门和地质部门的一项迫切任务。钾肥资源包括草木灰、含钾的卤水、含钾的硅酸盐矿物和岩石、可溶性钾盐等。其中
Potash has a significant effect on the increase of crops. Test results show that per kilogram of potassium oxide can increase grains 2.8-7.2 pounds, 33.3 pounds of potato, peanuts 7.1 pounds, 1.9 pounds of seed cotton, jute 4.1 pounds. In the case of increasing nitrogenous fertilizer and phosphorus fertilizer application and continuous increase of mu production of crops, the reserve of potassium in the soil is very consumed and will not be sufficient. Therefore, efforts to find potash resources to provide raw materials for the production of potash are an urgent task for the petrochemical and geological departments. Potash resources include ash, potassium-containing brine, potassium-containing silicate minerals and rocks, soluble potassium salts and the like. among them
