Taurine crystals are precisely loaded into the nanopores through vacuum impregnation technology. This structure effectively neutralizes the lipolysis toxicity of diols and triols in ginsenosides by slowly releasing taurine molecules, significantly reducing their damage to the membrane structure of lactic acid bacteria and yeast, thus improving the survival rate of EM bacteria. At the same time, the unique silica skeleton of diatomaceous earth constructs a microchannel system in the soil, breaking the dense layer structure of saline-alkali soil, increasing the water infiltration rate and oxygen diffusion efficiency, and greatly improving the root microenvironment. This can solve the contradiction between the inhibition of microbial activity and soil compaction in highly active ginseng fertilizers, allowing the ginseng bio-fertilizer to play its role effectively.
