[0054] The preparation method of pecan cattail shell fermentation powder is:
[0055] 1) Collect hickory cattail shells during the hickory harvest season;
[0056] 2) Screw extrusion to remove part of the moisture;
[0057] 3) Put the hickory cattail shell into the horizontal fermentation equipment for fermentation, the fermentation temperature is 55-60°C, and the fermentation time is 10-15 days (no large amount of gas is produced, and the fermentation can be judged to be completed when the fermented product has a rotten smell); Good hickory cattail shells are broken, sieved, and dried to obtain hickory cattail shell fermentation powder;
[0058] The obtained hickory cattail shell fermented powder has an organic matter content of more than 60 percent, a water content of less than 25 percent, and a 20-mesh passing rate of more than or equal to 90 percent.
[0059] The preparation method of the special organic slow-release fertilizer for cereal crops is as follows: mixing each...
