Abstract
The invention provides a special organic-inorganic blue-green alga compound fertilizer for corn and a preparation method thereof. The compound fertilizer comprises the following raw materials in parts by weight: 20-28 parts of blue-green alga powder, 35-46 parts of urea, 15-23 parts of monoammonium phosphate, 6-12 parts of potassium chloride, 0.5-3 parts of zinc sulfate, 0.5-1.5 parts of borax and 2-9 parts of sepiolite powder. The compound fertilizer has the advantages that the sepiolite powder is utilized as an adhesive due to adhesiveness to gain better granulation effects; the material granulation rate is high; the moisture content of the product is low, thus solving the problems that organic fertilizer products have high moisture contents and are powdered after being stored for a long time, thus being not suitable to sow by machine; the nutrient ratio of the product and abundant trace elements in the product are more suitable for the growth requirements of corn; and the product also has the effects of promoting fertilizer synergy, improving soil and improving the crop yield and quality.
