Method for improving desertification mine soil

The invention discloses a method for improving desertification mine soil, and a desertification mine soil conditioner comprises the following components in parts by weight: a plant immune resistance inducer, modified charcoal, crushed plants, a complex microbial inoculant, fly ash, a plant immune resistance inducer, a microbial inoculant, a biological humic acid fertilizer, an inorganic fertilizer, palygorskite, bentonite and polyaspartic acid. The method further comprises the step of improving the desertification mine soil. According to the invention, the modified charcoal used in the invention has the advantages of long lasting period, complete functions and low manufacturing cost; the soil pH is increased, the acid soil is improved, and the soil fertility is increased; heavy metals and organic pollutants are adsorbed and fixed, the activity of the heavy metals in the soil is reduced, and formation of soil aggregates is promoted; the conditioner prepared from the components according to the preparation meth
