Saline-alkali soil conditioner rich in salt-tolerant microorganisms and preparation method and device thereof

The invention discloses a saline-alkali soil conditioner rich in salt-tolerant microorganisms and a preparation method and device thereof, the conditioner comprises salt-tolerant bacteria, a sulfur-containing substance, potassium humate, decomposed livestock and poultry manure and decomposed straw, through the cooperation of multiple salt-tolerant bacteria microorganisms, the micro-ecological environment of soil can be improved, and the buffer performance of the soil is improved; according to the preparation device, the integrated layout of modifier production is achieved, the occupied space can be saved, the drying efficiency of organic particles is improved, during preparation, the granulation step and the strain inoculation step are carried out separately, high-temperature rapid drying is carried out after wet granulation, and the production efficiency is improved. The bacterial liquid is uniformly sprayed on the organic particles dried and cooled at high temperature through the bacterial liquid opposite s
