摘　　要：研究了不同来源的钾细菌制剂及KCl对水稻、小麦等作物生长的促进作用和增产效果。结果表明 ,钾细菌制剂对土壤矿物钾有较强的分解能力 ,在缺钾小粉白土中施用钾细菌制剂对水稻和小麦的生长有促进作用 ,能将更多的土壤无效钾转化为植物可吸收利用的速效钾。如在缺钾土壤中施用钾细菌制剂 ,能提高钾肥和土壤钾的利用率 ,经济效益显著 ,投入产出比达1∶9.2～ 2 2 .5。Effects of two bacterial potassium fertilizers,namely, Bacillus mucilaginosus preparations Bmp1 and Bmp2 from Yangzhou and Hebei in promoting growth of winter wheat or rice as well as in enhancing yield of crop are studied in Yangzhou. It is shown that application of Bmps in plots of potassium defficient soil such as chalky silt loam will promote growth of rice or wheat through transforming unavailable potassium in soil into available potassium that plants can absorb and utilize. Therefore,applying Bmp to potassium deficient soil as a cultural practice will enhance utilization rate of K in fertilizer and soil and so increase crop yield,giving significant economic effect,the ratio of input to output will be 1∶9.2 or 1∶22.5.
