土壤中含有丰富的磷、钾矿物,但主要呈铝硅酸盐及磷灰石等矿物态形式,不能直接被植物吸收利用。因此,应用钾细菌,促使这些磷、钾矿物转化为植物能够直接吸收利用的可给态,是值得我们很好研究的。近几年来,市郊连续进行了钾细菌大田肥效试验,施用钾细菌308菌株,三麦增产9.7％,油菜增产7.2％,同时对植物的某些病害也有减轻作用。为了了解钾细菌308的增产原因,我们在前人(注)研究的基础上,对钾细菌308菌株的作用机制作了一些研究,现将钾细菌308菌株对磷、钾矿物分解能力的研究小结如下。
Soil is rich in phosphorus and potassium minerals, but mainly in the form of minerals such as aluminosilicates and apatites, can not be directly absorbed by plants. Therefore, the application of potassium bacteria, to promote these phosphorus and potassium minerals can be directly absorbed into the plant can give state, it is worth our good study. In recent years, the suburbs of continuous potassium fertilizer field fertilizer efficiency test, the application of potassium bacteria 308 strains, three wheat yield 9.7% rapeseed yield 7.2%, while some plant diseases also have a mitigating effect. In order to understand the reasons for the increase of Potassium Bacteria 308, we made some research on the mechanism of Potassium Bacteria 308 based on the previous studies. Now we summarize the research on Potassium and Potassium mineral decomposition ability of Potassium Bacteria 308 strain as follows.
