钾细菌制剂对土壤钾素的影响探讨

Effect of Bacillus mucilaginosus preparation on potassium in soils

  • 摘要: 试验K 细菌制剂在控制条件和大田下对土壤难溶性K 的转化作用,特别是土壤速效钾和缓效钾的动态变化表明,缺K 土壤适当施用K 细菌制剂,可增加土壤速效钾含量,成熟植株体内K 增加32.3% ,拔节孕穗期土壤速效钾含量比对照高128.6% ,而土壤、磷矿粉、沙子等3种基质平均速效钾含量比对照高160.6% 。K 细菌制剂不板结土壤和不污染水源。

     

    Abstract: Effect of Bacillus mucilaginosus preparation on the transform ation of potassium of soil mineral in pot mineralization test and field test and particularly the dynamics changes between available potasium and slow acting potasium in soils are reported in the article.Results show that adequate Bacillus mucilaginosus preparation applied in potasium deftcient soil increases the available potasium,up to 128.6% in contrast to CK in jointing stage,and potasium adsorbed by plant,by 32.3% more than CK ,due posibly to the release of the mineral potasium in soil by a special enzyme produced by Bacillus mucilaginosus
