Problems solved by technology

Due to the influence of the physical and chemical environment of the soil, the antagonism between certain nutrient elements causes the nutrient elements to not be fully absorbed by the crops.
Part of it is lost, part of it is fixed by metal ions to become an exchangeable substance, and part of it is absorbed by soil colloid, which greatly affects the effective use of fertilizer components.
Many fertilizer technologies have made some efforts to solve these problems and made some progress. However, none of them jumped out of the scope of changing the relationship between elements, which not only affects the growth of crops, but also causes a great waste of fertilizers.

Abstract

The invention discloses a fulvic acid potassium chelating fertilizer, belonging to the technical field of agricultural fertilizers. The fulvic acid potassium chelating fertilizer comprises the following raw materials in parts by weight: 18 parts of chelating agent, 18 parts of heavy calcium carbonate, 20 parts of urea, 12 parts of ammonium sulfate and 8 parts of ammonium nitrate, wherein the chelating agent is made from copper sulfate, ferrous sulphate, zinc sulfate, manganese sulfate, boric acid, fulvic acid potassium, urea, ethylene diamine tetraacetic acid (EDTA) and the like. Strong complexing ability and rich nutrient substances of fulvic acid potassium are utilized in the invention by a scientific and simple method. The fulvic acid potassium chelating fertilizer has high fertilizer efficiency, meets growth need of crops, improves utilization ratio of the fertilizer, and reduces environmental pollution.

Description

technical field [0001] The invention relates to a chelate fertilizer, in particular to a potassium fulvate chelate fertilizer, which belongs to the technical field of agricultural fertilizers. Background technique [0002] The growth and development of crops requires a large amount of elements and medium and trace elements. This has been proved by theory and practice. When the large, medium and trace elements are made into compound (mixed) fertilizers, their function and fertilizer efficiency are better than those of simple fertilizers and some containing only large elements. Compound (mixed) fertilizer, which has been verified in agricultural production. Due to the influence of the physical and chemical environment of the soil, the antagonism between certain nutrient elements causes the nutrient elements to not be fully absorbed by the crops. Part of it is lost, part of it is fixed by metal ions to become an exchangeable substance, and part of it is adsorbed by soil colloi...
