近年来，土壤中的钾素养分逐年下降，已成为提高作物产量的主要限制因素。在工业钾肥货缺价扬的情况下，生物钾肥为农作物提供了钾源新途径。１９９６～１９９７年秋播我市采用江苏省农林厅与南京农业大学联合生产的高效（液体）生物钾肥在小麦上进行试验研究，探讨生物钾肥在?
In recent years, soil potassium nutrients have been declining year by year, which has become a major limiting factor for increasing crop yield. In the absence of industrial potash fertilizer Yang, bio-potash provides a new source of potassium for crops. From 1996 to 1997 autumn broadcast in our city with the Department of Agriculture and Forestry, Jiangsu Province and Nanjing Agricultural University, joint production of high efficiency (liquid) bio-fertilizer on wheat in the experimental study of biological potassium fertilizer in?
