Abstract

The invention discloses a preparation method of a healthy and environment-friendly rice special fertilizer. The preparation method comprises the following steps that waste straw, pig manure, biogas residue, coal ash, sunflower seed meal, humic acid and EM preparations are blended, water is added into the mixture, the mixture is sealed to ferment, and a fermented material is obtained; ammonium chloride, calcium magnesium phosphate and potassium nitrate are added to be stirred, dried and ground, the water content is adjusted, the mixture is ground to be 60-mesh, chitosan, medical stone powder and corn starch are added to be blended uniformly, and then subjected to pelletizing and drying, and the healthy and environment-friendly rice special fertilizer is obtained. The preparation method of the healthy and environment-friendly rice special fertilizer can not only provide sufficient nutrients to growth of rice, has the extremely good slow-release effect, but also can improve the situationof soil hardening caused by long-term use of the fertilizer in the soil, the permeability of the soil can be increased, the cost is low, and the production increasing and quality increasing effects ofthe rice are outstanding.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a method for preparing a healthy and environment-friendly special fertilizer for rice. Background technique [0002] Rice is one of the main food for people.
