Abstract

The invention discloses a compound fertilizer for controlling soil pollution. The compound fertilizer is used for improving soil for the alkalinity or acidity of soil to be repaired, after the pH of soil reaches an appropriate range, a chelating agent in the soil is used for heavy metal complexing, and a specific reactant generates antagonism with heavy metals in the soil, so that the complexing effect of the chelating agent for heavy meals is improved, and then the heavy metals in the soil are greatly fixed, the content of heavy metal ions in the soil is reduced, and the influence on plantingplants in the soil is reduced to a great extent. Moreover, edible fungus waste materials are added into the compound fertilizer, on one hand, the edible fungus waste materials react with heavy metalsto generate insoluble heavy metal complexes through organic matters, on the other hand, the edible fungus waste materials are also rich in abundant nutrient substances, and then the compound fertilizer also can meet the nutritional requirement of plants in soil under the condition of without adding other extra nutritional ingredients, so that the soil characteristics are indirectly improved.

Description

technical field [0001] The invention relates to the technical field of compound fertilizers, in particular to a compound fertilizer for controlling soil pollution. Background technique [0002] At present, soil pollution in some areas of my country is relatively serious, and heavy metals such as lead, cadmium, and mercury in the soil exceed the standard, which seriously affects the safety of crop production. Due to the increase in industrial pollution and the total use of automobiles, heavy metal dust enters the atmosphere in the form of aerosols, and enters the soil through natural sedimentation and precipitation, causing soil pollution. The pollution along the roads caused by automobile driving is particularly serious. The soil on both sides of the expressways in some provinces is seriously polluted, and the two sides of the roads have become lead-polluted areas. The lead content in vegetables, tea and other crops exceeds the standard, and the lead and unburned tetraethyl...
