The invention relates to the technical field of fertilizer, in particular to novel remediation water-soluble fertilizer. The novel remediation water-soluble fertilizer is prepared from the following raw materials in parts by weight: 10-30 parts of urea, 8-18 parts of ammonium nitrate, 10-30 parts of triple superphosphate, 10-30 parts of potassium nitrate, 8-18 parts of potassium sulfate, 8-12 parts of humic acid, 6-8 parts of compound micro-fertilizer, 10-20 parts of compound bacteria, 15-25 parts of a complexing agent and a right amount of water. The functional water-soluble fertilizer is prepared according to the fertilizer requirement law of crops and on the basis of soil fertility, pollution conditions, and the like, and is evenly distributed into the soil of the roots of plants by means of integration of water and fertilizer; the novel remediation water-soluble fertilizer can be accurately applied while meeting the requirements of the crops for various nutrients, can effectively permeate into the earth surface while increasing the fertilizer utilization efficiency, and can realize effective soil remediation; the water-soluble fertilizer is not only obvious in heavy metal repair effect, and but also has rich nutrition, thus effectively promoting the growth of the crops.
