Rotten phytic acid increase type slowly-releasing is muddy fertile granule again

The utility model discloses a rotten phytic acid increase type slowly-releasing is muddy fertile granule again belongs to slowly-releasing compound fertilizer technical field. Wherein, every compound thoughtlessly fertile granule from inside to outside by the kernel granule made including biological rotten phytic acid, the slowly-releasing layer of making by sustained release agent and urea and prevent compound the forming of caking layer three layer construction by what anti-caking agent made. Should compound mix the biological rotten phytic acid that fertile kernel granule contains, and be rich in organic matter, the dissolubility is strong, and the molecular weight I directly is absorbed by the crop, and multiple active material such as the multiple amino acid of microorganism production, phytohormone can promote the root system growth. Simultaneously, the rotten phytic acid of this biology has certain slowly-releasing function, and the microelement in the ability chelate soil, reduction phosphorus fixation loss have effectively improved fertilizer use efficiency, strengthen the resistance of crop. The slowly-releasing layer is in the urea thick liquids adding the controlled release agent, can slow down hydrolysis speed and the nitrification of urea in soil, and extension nutrient release time satisfies the crop middle and later periods to the demand of nutrient, prevention and cure early ageing.
