The invention provides a preparation method of soil moisturizing bio-fertilizer. The composite microorganism bactericide adopted in the invention comprises an A group bactericide and a B group bactericide, and fermentation preparation is completed by smashing straws, composting and secondary piling fermentation. Compared with the prior art, the invention has simple preparation technique without needing large mechanical equipment, simple and practical method, wide raw material source, and low cost, solves the difficulty in straw treatment, and realizes recycling of resources; the inventive soil moisturizing bio-fertilizer has strong water absorptivity which is increased by over ten times, good moisture retention property to soil, and can eliminate soil hardening and promote root system to grow, improve content of organic matter in soil by 1-1.5 times, reduce dosage of fertilizer by over 35% resulting in planting in the next season without applying fertilizer, adjust soil micro-ecological environment, and reduc
