Composite microbial fertilizer for soil improvement and preparation method thereof

Abstract

The invention relates to composite microbial fertilizer for soil improvement. The composite microbial fertilizer is prepared from the following components in parts by weight: 10 to 15 parts of alkaline phosphatase, 10 to 15 parts of sucrase, 10 to 15 parts of bacillus licheniformis, 10 to 15 parts of yeast strain, 20 to 50 parts of dandelion, 10 to 15 parts of gypsum, 15 to 25 parts of sodium alginate, 5 to 15 parts of calcium sulfate, 1 to 10 parts of humic acid, 1 to 5 parts of palm oil, 1 to 5 parts of ferrous sulfate, 10 to 20 parts of powdered rock phosphate, 20 to 30 parts of pine needle mulch, and 1 to 5 parts of trace elements. The composite microbial fertilizer improves soil nutrients and water retention properties of land.

Description

technical field [0001] The invention relates to a fertilizer, in particular to a compound microbial fertilizer for soil improvement; the invention also relates to a preparation method for the compound microbial fertilizer for soil improvement. Background technique [0002] Alkaline soil refers to the soil with a soil alkalinity greater than 7; that is, the concentration of hydroxide ions in the soil solution is greater than the concentration of hydrogen ions, and practically refers to the soil with a pH value above 7.3. But in nature, there are often various obstacles in the soil where plants grow, which limit plant growth. A serious problem on alkaline soil is low nutrient availability, and there are many types of nutrients involved, such as Alkaline soils generally lack nitrogen, phosphorus and potassium; many soils lack calcium and magnesium; some soils lack manganese, and the lack of these nutrients is mainly determined by the characteristics of alkaline soil composition...

AI Technical Summary

Problems solved by technology

But in nature, there are often various obstacles in the soil where plants grow, which limit plant growth. A serious problem on alkaline soil is low nutrient availability, and there are many types of nutrients involved, such as Alkaline soils are generally deficient in nitrogen, phosphorus and potassium; many soils are deficient in calcium and magnesium;

The soil for planting crops requires rich nutrients and the land has a certain water retention performance. The lack of nutrients caused by alkaline soil will cause great damage to the land harvest.
