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。
The effects of different sources of potassium bacteria and KCl on the growth of rice and wheat and other crops were studied. The results showed that potassium bactericide had strong ability to decompose soil mineral potassium, potassium bactericide could promote the growth of rice and wheat in potassium deficiency silt clay, and convert more available potassium into plant Absorption and utilization of available potassium. For example, applying potassium bacteria in potash-deficient soil can increase the potassium utilization rate of potash and soil, and the economic benefit is remarkable with the input-output ratio of 1: 9.2-2.25.
