Problems solved by technology

[0003] The fertilizer efficiency of slow-release fertilizers depends on the slow-release material and the form of coating. It is common in the market to use the same or different coating materials to achieve layered coating and then achieve slow-release regulation, but this will increase material costs and production costs.

Abstract

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.

Description

technical field [0001] The invention belongs to the field of slow-release fertilizers, and in particular relates to a high-efficiency slow-release fertilizer for mountain apricots in dry land on hillsides and a preparation method. Background technique [0002] Coated slow-release fertilizer can significantly improve the utilization rate of fertilizer. However, the vast majority of slow-release fertilizers currently on the market are facing many problems, for example: 1. The coating material is made of chemically synthesized non-degradable polymers, and these refractory polymer coating materials are easily left in agricultural fertilizers. Soil degradation and serious pollution are caused in the soil; 2. The coating material is made of natural polymer degradable materials, but the slow-release fertilizers made of these natural polymer degradable materials are too expensive on the one hand, and the controlled release effect is not good on the other hand , with the degradation...
