土壤磷活化剂,是河北省微生物研究所最新研制的液体型复合菌剂,是采用巨大芽孢杆菌和胶质芽孢杆菌经多级液态深层发酵而成。该制剂施入土壤后,既能将土壤中固定态的磷分解转化成速效磷,又能将无效钾分解转化为速效钾,有利于作物的吸收 Soil phosphorus activator, Hebei Institute of Microbiology is the latest development of the liquid composite bacterial agent, is the use of Bacillus megaterium and Bacillus coli by multi-level liquid fermentation from deep. After applied to the soil, the preparation not only converts fixed phosphorus in the soil into quick-acting phosphorus but also decomposes the ineffective potassium into quick-acting potassium, which is good for crop absorption
