Description
Technical Field
The invention relates to the technical field of fertilizers, in particular to a microbial fertilizer for improvement of a spot-shaped salinized area in Huang-Huai-Hai.
Background
The characteristics of the soil in the spot salinized area of Huang-Huai-Hai are as follows: the cause of the spotted salinized area of the Huang-Huai-Hai is that coastal climates of the Huang-Huai-Hai and the Huai-Hai are arid, evaporation is vigorous, and underground water is excessively exploited in the coastal area, so that seawater invades the land to be salinized, and the salinized land is lack of nutrients and poor in ventilation due to the fact that the underground water level rises and water evaporates. The microbial fertilizer has the advantages that: the beneficial bacteria can be propagated in a large quantity to form dominant species around the root system of the plant, so that the life activities of other harmful bacteria are inhibited. The biomass in the soil can be rapidly decomposed, the formation of soil granules is promoted, the soil can be loosened through the activity of beneficial bacteria, and the fertilizer, water and air permeability of the soil are well regulated. Meanwhile, pesticide residues in soil can be decomposed, pesticide damage of residual pesticides to crops in the next season is avoided, and harmful substances discharged in the root system growth process are decomposed.
