生物钾肥是南京农业大学微生物研究室研制的新一代细菌性肥料，其作用机理是活化土壤中难溶性钾元素为作物所吸收利用，增补作物钾素的不足。为探索生物钾肥在我地自然条件下对农作物的增产作用，1994～1996年，根据江苏省作物栽培指导站的安排，我们在啤麦上进行了生物钾肥的 Biological potassium fertilizer is a new generation of bacterial fertilizer developed by the Microbial Research Office of Nanjing Agricultural University. The mechanism of action is to absorb insoluble potassium in the soil for crop absorption and utilization, and to supplement the deficiency of potassium in crops. In order to explore the effect of bio-potash fertilizer on crop yield increase under natural conditions in our country, from 1994 to 1996, according to the arrangement of Jiangsu Provincial Crop Cultivation Guide Station, we conducted bio-potash fertilizer
