Abstract
This invention relates to a humic acid complex urea and the method of making same, by charging 465-550 share urea and 35-45 share humic acid. The process comprises: dissolve the humic acid to 120-160 share water with temperature no more than 25Deg C in autoclave A, dissolve the urea to 280-390 share water with temperature no more than 40Deg C in autoclave B, add the dissolved humic acid in autoclave A into autoclave B, slowly add in phosphoric acid with pH test at the same time until pH 5-7, so as to produce the invented flavic acid complex liquid fertilizer. This invented flavic acid complex liquid fertilizer has been dissolved and formed biuret while being applied, providing benefits of being easily and fast absorbed by plants, and quick effect, which is suitable for being used in current broadly applied dropping and spraying planting modes.
Description
Technical field
The present invention relates to a kind of detritus acid complexing liquid fertilizer and production method thereof, especially a kind of fulvic acid complex liquid fertilizer and production method thereof.
