Method for preparation of biomass agricultural soil conditioner based on crop straw

Relating to the technical field of agricultural arable land treatment, the invention provides a method for preparation of a biomass agricultural soil conditioner based on crop straw. The method consists of: selecting crop straw, conducting primary treatment, then performing decomposition and milling, mixing the obtained powder with the residual components, adding water to conduct stirring, and then performing drying and granulation, thus obtaining the soil conditioner. The method provided by the invention has the advantages of concise process and reasonable selection of raw materials, converts polluted straw in current agricultural plantation into an arable land pollution control product, and in actual processing, the cost is low, with a good use effect, the soil conditioner is flexible and convenient for application, effectively performs corresponding treatment on polluted agricultural arable land, improves the soil viscosity, and increases the loose degree of soil, thus being convenient for root expansion,
