The invention provides a combination technology of soil disinfection and soil restoration, including preparation before soil disinfection, soil disinfection and soil restoration. Before soil disinfection: the plowing depth is 40-50cm; the border height is 20-30cm; the height between the film and the soil in the border is 10-20cm. The soil disinfectant used includes the following components: dithiocarbamate, sodium formate, 2-chloroisobutyl nitrite, borax, cyclodextrin, laminarin, and phthalimide. The soil remediation agent used includes the following components: microbial powder, sodium alginate, 2-hydroxybenzoic acid-5-sodium sulfonate, β-cyclodextrin, sodium caseinate, medical stone powder, EDTA-iron, Corn protein peptide, polyglutamic acid, polyacrylamide, earth wattle powder. The technology of the invention has obvious control effects on root rot, canker, fusarium wilt, verticillium wilt, bacterial wilt and stem base rot of plants, and at the same time has obvious improvement on soil properties.
