It 20-50 parts, continues to use mixed stirring device and is stirred, the time control of stirring is in 1-1.5h to get to mixing organic fertilizer；
5) 4-10 parts of copper nitrate, 4-8 parts of chitosan, 10-15 parts of soybean protein and 2-6 parts of pure selenium powder are put into stirring
In machine, and water appropriate is added, stirs 45-60 minutes, after stopping stirring, so that the temperature fall control in blender exists
15-20 DEG C, the mixing organic fertilizer in step 4) is added in blender together then and is stirred work, this time stirring when
Between be 30-50 minute, then be made selenium-rich mixed fertilizer；
6) selenium-rich mixed fertilizer obtained in step 5) is put into batches in molding granulation machine and carries out granulation work, it then will system
Fertilizer particle be sequentially placed into drying box and carry out drying operation, by the fertilizer particle after drying be put into blow box into
The blowing work of the floating powder of row, is finally packaged using packing machine, packed bag with fertilizer is put into storage chamber and is deposited
It puts, stores indoor temperature control at 23-27 DEG C, obtain a kind of biological selenium-enriched fertilizer.
