The invention discloses an organic slow-release
fertilizer special for corn. The organic slow-release
fertilizer special for corn is prepared from, by weight, 54-56 parts of soybean
straw, 32-34 parts of sweet potato vines, 3.5-3.7 parts of
citric acid residues, 4.2-4.4 parts of pepper
meal, 6.5-6.7 parts of
bone meal, 4.4-4.6 parts of coffee residues, 0.05-0.07 part of triadimenol, 11-13 parts of
potassium nitrate, 14-16 parts of
ammonium phosphate, 7-9 parts of
monopotassium phosphate, 0.21-0.23 part of
bacillus megaterium, 0.14-0.16 part of
rhizobium astragali, 0.27-0.29 part of
azotobacter chroococcum, 3.6-3.8 parts of cattail leaves, 4.1-4.3 parts of
potamogeton crispus, 2.7-2.9 parts of
yucca gloriosa leaves, 3.2-3.4 parts of ervatamia divaricata leaves, 4-6 parts of clay and 3-5 parts of
bentonite. The organic slow-release
fertilizer special for corn is scientific and reasonable in formula, all raw materials act complementarily, the functions of effectively increasing and updating
soil organic matter, prolonging fertilizer action time, promoting full absorption, utilization and conversion of corn to nutritional ingredients, achieving a high
ripening rate and making grains full can be achieved, and the functions of effectively decreasing the monolepta hieroglyphica
insect damage rate and the leaf
blight disease damage rate and increasing the yield and hundred-
grain weight of corn can also be achieved, so that higher economic profits are brought to farmer households.
