Abstract

The invention discloses a compound fertilizer for remediation of organic contaminated sandy saline-alkali soil. The compound fertilizer comprises an organic fertilizer, a compound water-retaining agent, a sandy saline-alkali soil remediation agent and an organic contaminated soil remediation agent in a weight ratio of (29-33):(10-14):(15-19):(38-42). The invention also discloses a preparation method of the compound fertilizer. The compound fertilizer provided by the invention can effectively improve the structure of the sandy saline-alkali soil, reduce the salinity and alkalinity, improve a nutrient content of the soil, reduce a content of organic pollutants in the soil and effectively remediate the saline-alkali soil for a long time.

Description

technical field [0001] The invention belongs to the technical field of saline-alkali land improvement, and in particular relates to a compound fertilizer for remediation of organically polluted sandy saline-alkali land soil and a preparation method. Background technique [0002] With the development of society, a large number of chemical factories have been relocated to the seaside tidal flats in order to avoid living areas and working areas. The deterioration of the soil has seriously affected the growth of plants in the area and brought a devastating blow to the ecology of these areas. [0003] At present, the treatment of chemical pollution generally adopts physical and chemical joint remediation method, chemical and biological joint remediation method, plant and microorganism joint remediation method and soil leaching remediation technology. Among them, the organic pollution remediation technologies include chemical oxidation technology, thermal desorption technology, c...
