AI Technical Summary

Technical Problem

Traditional chemical fertilizers lead to soil compaction, acidification, and a decline in organic matter. Microbial fertilizers are insufficient in nutrients, making it difficult to meet the high concentration requirements of rice. Furthermore, the activity of microbial agents is low, resulting in poor disease resistance. Existing microbial strain combinations are limited and lack synergistic mechanisms, making it difficult to achieve the multiple goals of promoting growth, disease resistance, and nutrient release.

Method used

A combination of photosynthetic bacteria, Bacillus subtilis, Bacillus mucilaginosus, Trichoderma harzianum, Bacillus polymyxa, and Bacillus megaterium, along with well-rotted cow manure, fermented soybean meal, potassium humate, zinc sulfate, sodium molybdate, sodium silicate, and bentonite, forms a synergistic metabolic network. The bacteria are protected by a bentonite carrier for slow release and a sodium alginate cross-linked membrane, thus meeting the growth requirements of rice.

Benefits of technology

It increased the ammonium nitrogen content in the soil, reduced the incidence of diseases, improved the thousand-grain weight of rice and the nutrient supply during the tillering stage, enhanced cell wall disease resistance, and achieved a synergistic effect of efficient nutrient utilization and disease control.
