Soil improvement additive and preparation method thereof

[0045] A soil improvement additive and a preparation method thereof, comprising the following raw materials in proportions by weight: 100kg / mu of ore mixture, 500kg / mu of farm manure, 80kg / mu of inorganic fertilizer, 100kg / mu of fungal chaff, and 50kg / mu of mixed bacterial agent And auxiliary material 100kg / mu, described ore is the combination of one or two kinds of calcite and potassium feldspar, select pure ore to be calcite and potassium feldspar, and clean up, the harmful The ore powder is 80-100 mesh. The ore particles with too large mesh are not conducive to the growth of crops. The powder with too small mesh can not improve the soil. The spongy porous of the ore can be used It can loosen the soil and play a moisturizing role, which can improve soil compaction, and can use its specific medicinal effects (clearing heat and dampness, dredging the veins and detoxifying), thereby promoting the growth of beneficial microorganisms and inhibiting the growth of harmful m
