Problems solved by technology

[0003] Most of the organic compound fertilizers currently on the market only provide nutrients and trace elements for the soil, and some improve the soil structure to achieve slow release of nutrients, but most of the heavy metal elements in the soil cannot be degraded, so it is urgent to design a garden. The water-retaining slow-release organic compound fertilizer that degrades soil heavy metal elements solves the problems in the prior art

Abstract

The invention discloses a water-retaining slow-release organic composite fertilizer for gardens to degrade heavy metal elements in soil. The water-retaining slow-release organic composite fertilizer contains the following raw materials: pig manure, mushroom dregs, perlite, vermiculite, sludge, coal ash, biogas residues, kaolin powder, borax, sulfur coated urea, a modified slow-release agent, a modified degradation agent, a soil improver, monoammonium phosphate, potassium fulvic acid, ammonium chloride, diammonium hydrogen phosphate, ferrous sulfate, zinc sulfate, ammonium molybdate, composite ammonium nitrate, ammonium sulfate, stannous chloride and sodium hydrogen sulfite. The organic composite fertilizer disclosed by the invention is capable of degrading metal elements in soil and is excellent in water retention and slow release property.

Description

Technical field [0001] The invention relates to the technical field of fertilizers, in particular to a water-retaining and slow-release organic compound fertilizer used for gardens to degrade soil heavy metal elements. Background technique [0002] Heavy metals are highly toxic, carcinogenic, mutagenic, difficult to degrade, and easy to accumulate. Heavy metals cannot be biodegraded after entering the environment, but they participate in the food chain cycle and accumulate in organisms, destroying the body’s metabolism and harming The health of the human body, especially harmful to the human body, can cause mutations in human genes and cancerous cells. [0003] At present, most of the organic compound fertilizers on the market only provide nutrients and trace elements to the soil, and some improve the soil structure to achieve slow release of nutrients, but most of the heavy metal elements in the soil cannot be degraded, so there is an urgent need to design a garden The water-reta...
