Abstract

The invention discloses a special rice water-soluble fertilizer for inhibiting adsorption of heavy metal lead, and a preparation method thereof, and belongs to the technical field of fertilizers. Thefertilizer is prepared from glutamic acid fermentation tail liquid, a microbial agent, potassium silicate, calcium superphosphate, diammonium phosphate, urea, potassium fulvate, potassium chloride, ammonium bicarbonate, alternaria tenuissima activator protein, ethylene diamine tetraacetic acid disodium salt and polypropylene alcohol according to a certain weight ratio. The fertilizer can effectively reduce activity of lead in heavy metal contaminated soil, absorption of rice to lead is reduced, and guarantee is provided for food safety of people.

Description

technical field [0001] The invention relates to a water-soluble fertilizer, in particular to a special water-soluble fertilizer for rice which inhibits the absorption of heavy metal lead and a preparation method thereof. Background technique [0002] Water-soluble fertilizer is a multi-component compound fertilizer that can be completely dissolved in water. Compared with traditional simple fertilizers and compound fertilizers, it has the advantages of easy absorption and high utilization rate. This characteristic of water-soluble fertilizer enables it to be combined with new agricultural technologies such as sprinkler irrigation and drip irrigation to realize the integration of water and fertilizer. Under the current severe situation of excessive fertilizer input in agricultural production, water-soluble fertilizers have become one of the effective ways to achieve the goals of water saving and weight loss. [0003] In recent years, the long-term accumulation of soil polluti...
