Abstract

The present invention relates to a biological multicomponent phosphorus potassium fertilizer. The raw material for producing said biological multicomponent phosphorus potassium fertilizer is potassium-contained shale, in which the main components are SiO2, P2O5, K2O, B, Zn, Mo, Cn, Fe2O3, Mn, S, Se and Na2O, etc. Its preparation method includes the following steps: breaking natural potassium-contained shale containing the above-mentioned various components, adding phosphorus-decomposing and potassium-decomposing bacterial strains in broken ore powder, stirring and uniformly mixing them and ferment the mixture for 10 days at normal temperature.

Description

technical field [0001] The invention relates to a biological multivariate phosphorus and potassium fertilizer, which belongs to the technical field of agricultural fertilizers. Background technique [0002] Fertilizers are food for crops. The "three elements" of nitrogen, phosphorus, and potassium are the same as the "three major nutrients" of carbohydrates, protein, and fat necessary for human survival, and are indispensable nutrients for the survival of all living things. For this reason, countries all over the world are looking for new fertilization methods and new fertilizer sources. [0003] Since the 1980s, with the rise of high-yield cultivation techniques, the popularization and application of new varieties, and the improvement of irrigation conditions, the multi-cropping index of farmland has increased, and the yield per unit area of ​​farmland has been greatly improved; The absorption of mineral nutrients in the soil also increases accordingly. In order to achie...
