摘　　要：基于国内对钾长石化学活化和生物活化的长期研究,开展了有关钾长石生物-化学协同活化的试验。试验以水溶性钾和速效钾含量为指标,进行菌株、活化剂及联用组合的优选评价,再通过玉米盆栽试验验证其肥效。结果表明,解钾菌Q22与活化剂CM联用,钾长石在常温条件下经8~12 h生物-化学协同活化,可取代50%的氯化钾用量并获得明显的增产效果。Based on the long-term research on chemical and biological activation of potassium feldspar in China, experiments on the biochemical synergistic activation of potassium feldspar are carried out. In the experiment, the content of water-soluble potassium and available potassium is taken as the index to optimize and evaluate the bacteria, activator and their combination, and then the fertilization effect is verified through maize pot experiment. The results show that the combination of potassium bacteria Q22 as well as activator CM and potassium feldspar being activated by biochemical synergism for 8-12 hours at room temperature can replace 50% of potassium chloride and obtain obvious yield increase effect.
