生物钾肥是指具有高钾低氮磷养分组成的植物的绿色体或秸杆。生物钾肥作用的实质是:植物不断吸收并活化土壤钾,富集土壤和水体中钾,通过以绿色体或秸秆形式归还,促进土壤钾的良性循环和再利用。生物钾肥中钾的溶解度和利用率都较高,其供钾性能类似矿质钾肥。在等钾量下,各种生物钾肥的增产效果和矿质钾肥接近。 Bio-potash refers to the green body or straw of a plant with a high potassium, low N-P nutrient content. The essence of bio-potash is that plants continuously absorb and activate soil potassium, enrich potassium in soil and water, and promote the virtuous cycle and reuse of soil potassium by returning as green body or straw. Potassium bio-potassium solubility and utilization are higher, similar to its potassium for mineral potassium. In the same amount of potassium, a variety of bio-potash fertilizer yield and mineral potassium close.
