The germination phase fertilizer is particles of inorganic fertilizer core body and fertilizer hydrogel layer wrapped at outside of inorganic fertilizer core body. The development phase fertilizer is particles of inorganic fertilizer core body and chicken manure layer and fertilizer hydrogel layer wrapped at outside of inorganic fertilizer core body.    USE - Used as slope protection herbaceous plant three-stage slow-release fertilizer.    ADVANTAGE - The fertilizer provides nutrients and promotes healthy growth of plants.    DETAILED DESCRIPTION - Slope protection herbaceous plant three-stage slow-release fertilizer comprises 20-25 pts. wt. germination phase fertilizer, 30-40 pts. wt. development phase fertilizer and 40-50 pts. wt. growth phase fertilizer. The germination phase fertilizer is particles of inorganic fertilizer core body and fertilizer hydrogel layer wrapped at outside of inorganic fertilizer core body. The development phase fertilizer is particles of inorganic fertilizer core body and chicken manure layer and fertilizer hydrogel layer wrapped at outside of inorganic fertilizer core body. The growth phase fertilizer is particle of inorganic fertilizer core body and chicken manure layer, fertilizer celite layer and fertilizer hydrogel layer wrapped from the inside to the outside of inorganic fertilizer core body. An INDEPENDENT CLAIM is also included for preparing the slope protection herbaceous plant three-stage slow-release fertilizer, comprising (i) taking 13-16 pts. wt. urea, 12-15 pts. wt. diamine phosphate, 4-5 pts. wt. potassium sulfate, 10-15 pts. wt. of 80-100 meshes starch and 10-15 pts. wt. environmentally sensitive hydrogel; mixing urea, diamine phosphate and potassium sulfate, adding 50-60 pts. wt. water, mixing and dissolving completely to form a mixed solution; adding starch into the mixed solution, heating, dissolving completely, stirring the mixed solution to form colloid; pouring the colloid into convex shape mold, cooling, condensing into particles and forming germination phase inorganic fertilizer core body; and adding environmentally sensitive hydrogel into inorganic fertilizer core body, granulating, completely wrapping the inorganic fertilizer core body and low-temperature drying; (ii) taking 10-13 pts. wt. urea, 15-18 pts. wt. diamine phosphate, 9-10 pts. wt. potassium sulfate, 10-15 pts. wt. of 80-100 meshes starch, 30-40 pts. wt. chicken manure fermentation powder and 10-15 pts. wt. environmentally sensitive hydrogel; mixing urea, potassium sulfate and diamine phosphate, adding 50-60 pts. wt. water into the mixed material and dissolving completely to form a mixed solution; adding starch into the mixed solution, heating and dissolving completely, stirring the mixed solution to form a colloid; pouring the colloid onto a convex shape mold, cooling, condensing into particles, forming development phase inorganic fertilizer core body; adding chicken manure fermentation powder into development phase inorganic fertilizer core body, introducing into a disc pelletizer, rolling and granulating, completely wrapping chicken manure fermentation powder with development phase inorganic fertilizer core body surface and forming the development phase chicken manure fertilizer layer; and adding fertilizer granule into environmental sensitive hydrogel, completely wrapping fertilizer particles with hydrogel to form development phase fertilizer hydrogel layer and low-temperature drying; and (iii) taking 5-8 pts. wt. urea, 10-15 pts. wt. diamine phosphate, 5-6 pts. wt. potassium sulfate, 10-15 pts. wt. of 80-100 meshes starch, 50-60 pts. wt. chicken manure fermentation powder, 20-25 pts. wt. celite powder and 10-15 pts. wt. environmentally sensitive hydrogel; mixing urea, diamine phosphate and potassium sulfate, adding 50-60 pts. wt. water to dissolve the mixed material and forming a mixed solution; adding starch into the mixed solution, heating, dissolving completely, stirring the mixed solution to form a colloid; adding the colloid into convex mold, condensing into particles to form inorganic fertilizer core body; adding inorganic fertilizer core body into chicken manure fermentation powder, introducing into a disc pelletizer, rolling and granulating, wrapping the chicken fermented manure with inorganic fertilizer core body outer surface to form chicken fertilizer manure layer; adding fertilizer particles into celite powder, introducing into the disc pelletizer, carrying out second tumbling granulation, completely wrapping celite powder on outer surface of the chicken manure fertilizer layer to form celite fertilizer layer; adding fertilizer particles into the environmentally sensitive hydrogel, granulating, completely wrapping the fertilizer granules with hydrogel to form hydrogel fertilizer layer growth and low-temperature drying; and (iv) mixing germination phase fertilizer, development phase fertilizer and growth phase fertilizer.
