摘　　要：研究钾细菌制剂用作早期追肥在小麦上的应用效果 ,结果表明 ,在缺钾土壤上施用钾细菌制剂能将土壤中的矿物钾转化为小麦可吸收利用的速效钾 ,促进小麦植株体内钾的积累 ,比对照增加 2 9.8% ,改善小麦植株性状和穗粒结构 ,最终增产 2 3 .3 3 % ,投入产出比为 1∶ 2 3 .85 ,具有明显的经济效益和生态效益。Effect of Bmp (Bacillus mucilaginosus Preparation) used as early seedling bacterial K fertilizer on wheat was studied.The results showed that Bmp can transfer undissolved mineral potassium in soils into fast available potassium adsorbed by wheat plant in potassium difficient fields.Bmp promots the accumulation of potassium in wheat plant,by 29.8% compared with CK;improves wheat appearance characters and panicle-grain constructures and leds to increase yield by 23.33% with the ratio of input/output of 1∶23.85.
