By the degradable aggregate of preparation, it is added in material C and stirs 20s~50s, obtain initial material；
Initial material is poured into concrete mold, and vibrates 7s~10s on a vibration table, demoulding is after maintenance one day to get to certainly
The concrete for plant growth of nutrition and adjustable porosity.
8. as described in claim 1 from nutrition and the preparation method of the concrete for plant growth of adjustable porosity, which is characterized in that can drop
Solving aggregate processing method includes：Taking partial size is 100.00 parts of the broken corn of graininess, the saccharomycete 0.31 of 1.20mm~4.80mm
Part~0.52 part, 0.27 part~0.48 part of bacillus subtilis, 0.19 part~0.45 part of mould, actinomyces 0.11 part~0.37
Part, 17.00 parts~38.00 parts of water；All material is placed in container and stirs evenly post-fermentation, 30.00 DEG C of temperature of holding~
It 50.00 DEG C, takes out after the 36h~78h that ferments stand-by.
