Abstract

The invention discloses a novel multi-element ecological chelate fertilizer and a making method thereof. The fertilizer comprises urea, ammonium sulfate, monoammonium phosphate, potassium sulfate, potassium nitrate, anhydrous magnesium sulfate, nitrate tetrahydrate, 0.6-1.2 parts of zinc sulfate heptahydrate, ferrous sulfate heptahydrate, copper sulfate pentahydrate, boric acid, a synergistic chelating agent (citric acid+ammonia water+glycolic acid) and a biodegradable chelating agent trisodium ethylenediamine disuccinate. Through appropriate compatibility of the synergistic chelating agent and EDDS (ethylenediaminedisuccinic acid), the compound chelating agent is biodegradable, the chelating properties are significantly improved, trace elements in the fertilizer are subjected to two chelating reactions to form a water-soluble reticular chelate, and then the water-soluble reticular chelate and macroelements nitrogen, phosphorus and potassium are subjected to granulation, thus obtaining the product. The product has the advantages of wide pH application range, good water solubility, balanced nutrients and easy absorption, avoids nutrient deficiency symptom caused by antagonism between nutrient elements, increases crop yield, improves the quality of agricultural products, and enhances the fertilizer utilization rate by 10-15%.

Description

technical field [0001] The invention relates to the technical field of agricultural fertilizers, in particular to a novel multi-element ecological chelated fertilizer and a manufacturing method thereof. Background technique [0002] my country is a big agricultural country, using 7% of the world's arable land to feed 21% of the world's population. Fertilizer is used as grain, and 50% of the increase in grain production comes from the contribution of fertilizer. However, due to unscientific and reasonable fertilization, heavy metals in the soil in our country exceed the standard, soil compaction, soil secondary salinization, and soil acidification. Unreasonable fertilization is mainly manifested in excessive fertilization, improper fertilization methods, and unreasonable fertilization structure. In recent decades, in order to pursue high yields, people have applied excessive amounts of chemical fertilizers, resulting in serious fertilizer loss, resulting in eutrophication of...
