目前常用的钾素化肥有四种。硫酸钾:含钾48-52%。呈白色或淡黄色结晶体。稍吸湿,不结块,易溶于水。为化学中性、生理酸性速效钾肥。适用于各种作物,各类土壤。施用方法:1、因钾在土壤中的移动性小,以作基肥和早期追肥效果好,追肥过晚肥效较差。宜采用条施、穴施集中施肥方法,把肥料施到作物根系密集的土层中。2、每亩施用量15～25斤。对于保肥能力差的砂性土,要少量多次的施
There are four commonly used potassium fertilizers. Potassium sulfate: potassium 48-52%. White or light yellow crystals. Slight moisture absorption, non-caking, soluble in water. For chemical neutral, physiological acid fast-available potassium. For a variety of crops, all kinds of soil. Application method: 1, due to potassium mobility in the soil is small, as a base fertilizer and early dressing effect is good, too late dressing fertilizer effect. Should adopt Article facilities, points in the collection of fertilization methods, the fertilizer applied to crop roots dense soil. 2, 15 ~ 25 kg per acre application. Abundant fertility for sandy soil, to a small amount of Shi Shi
