The invention belongs to the field of slow release fertilizer, and specifically discloses an efficient slow-release fertilizer for Armeniaca sibirica on hillside dry land. The fertilizer is characterized by including the following components by weight: micron calcined broiled fish bone meal, attapulgite clay, polyacrylamide, mesoporous silica nanoparticles, tamarind polysaccharide, konjac polysaccharide, calcium stearate, sodium oleate, chelated zinc, maleic anhydride, organic acid chelated titanium, medium trace element, Ginkgo biloba fermented powder, eucommia leaf fermented powder, fly maggot powder, and sugar residue. Attapulgite clay, tamarind polysaccharide and konjac polysaccharide are chelated to prepare a water absorbing and holding of slow -release coating material; while materials of different sizes are added to enrich the pore size of the coating material, control the nutrient release rate, reduce the degradation rate of the coating material, and prolong the fertilizer efficiency. The Ginkgo biloba leaf fermented powder, eucommia leaf fermented powder, fly maggot powder and sugar residue provide rich nutrition for Armeniaca sibirica and promote the efficient cultivation of Armeniaca sibirica.
