Abstract

The invention relates to a biological preparation for repairing soil. The biological preparation comprises the following components in parts by weight: 1.5-5 parts of a microbial preparation, 15-25 parts of single-walled carbon nanotubes, 60-90 parts of vinegar lees, 10-30 parts of soybean meal powder, 10-20 parts of tea bran powder and 5-10 parts of animal bile, wherein the microbial preparationis prepared by mixing trichoderma, nitrogen-fixing bacteria, streptomyces, bacillus megaterium, bacillus subtilis, bacillus natto and bacillus laterosus according to a volume ratio of 4-8:6-10:3-5:2-5:2-4.5:5-9:5-10, and the bacterial activity of each bacterium is not lower than 10<9> / g. According to the invention, the biological preparation can effectively increase the nutritional ingredients andbeneficial flora of soil, and effectively reduce the pH value of soil and the harm of heavy metals.

Description

technical field [0001] The invention relates to a biological agent, especially a biological agent for repairing soil. Background technique [0002] In recent years, the problems of soil salinization, impoverishment and soil compaction have become increasingly prominent. In addition, unscientific fertilization, large amounts of pesticide residues, and unreasonable application of chemical fertilizers have caused problems such as soil acidification or salinization, excessive heavy metal content, and soil compaction. High content of water-soluble salt in saline-alkali soil affects the growth and development of plants through osmotic stress or ion poisoning, or causes ion imbalance in the soil, making plants unable to use nutrients and inhibiting growth and development; soil compaction leads to soil water retention, fertilizer retention and permeability Excessive heavy metal content will damage the chloroplast structure of plants, resulting in blocked photosynthesis, reducing pla...
