Abstract

The invention relates the chelating water aqua boron fertilizer, which is made by 35-44wt% inorganic boron, 42-5wt% polyatomic alcohol, hydroxy compound(pH6-8) and 11-14wt% water reacting for 6-8 hours under 90-120Deg.C. The inorganic boron is boracic acid and natrium boricum, the polyatomic alcohol is ethylene alcohol, glyceryl alcohol, butylene glycol or pentaerythritol, and hydroxy compound is natrium hydroxydatum or potassium hydrate. The invention has the advantages of improving crop output, modifying crop quality and improving biological stress. When the soil is short of boron, the invention can modify the symptom, modifying crop quality and improving biological stress.

Description

Technical field: [0001] The invention relates to boron fertilizer, in particular to a chelated water-based boron fertilizer. Background technique: [0002] At present, most boron fertilizers are inorganic powder fertilizers (such as boric acid, borax, etc.), which are difficult to dissolve in water at normal temperature. Only when the water temperature is 50-60 degrees, can they be completely soluble, and they will crystallize immediately when they meet cold water after dissolving. Utilization is very low. In recent years, the Sule boron fertilizer introduced from the American Borax Company and the domestically produced instant boron fertilizer, although soluble in water, still exist in the state of borate, which is also inorganic, and the utilization rate of boron is very low. [0003] Although domestic also has the boron fertilizer kind of aqua, most is to dissolve borax or boric acid with water as solvent, and the content of boron in its aqueous solution is below 2%, can...
