Mineral source humic acid type microbial soil conditioner

The invention relates to the technical field of soil reform, in particular to a mineral source humic acid type microbial soil conditioner which comprises the following components: 1-5 parts of mineral source humic acid, 0.5-2.5 parts of a neutralizer, 0.8-3 parts of a complexing agent, 1-5 parts of charcoal, 0.1-0.5 part of a microbial agent, 0-0.6 part of a diatom agent, 0-0.7 part of sepiolite powder and 12-60 parts of a fertilizer. According to the method, the plant height, root length, biomass and chlorophyll content of corn seedlings are increased, enrichment of Cd and Pb by the corn seedlings is reduced, the arsenic absorption amount of plants is reduced, the toxic action of arsenic on the plants is relieved, moreover, compared with biochar and humic acid, increase of the copper content of wheat ears caused by copper pollution can be more effectively relieved, the effect of improving copper-polluted soil is better, and the yield of the copper-polluted soil is increased. The potassium humate, the organic
