Abstract: The production technology involved using microbial protectant to encapsulate microbial agents and then incorporating them into high nutrient content compound fertilizers, resulting in compound formula fertilizer with high active microorganisms and high nutrient content. Field experiments were conducted to assess their effects on the growth, nutrient absorption and quality of pepper（Capsicum annuum L.） and tomato（Solanum lycopersicum L.）. The results indicated that after granulation under the condition of 40% nutrient content, the viable microorganism count could reach 7.21× 10⁹ CFU/g, and the survival rate after six months of storage was 91.67%. The compound formula fertilizer with high active microorganisms and high nutrient content significantly promoted vegetable growth and improved both fruit quality and yield. Compared to vegetable specific formula fertilizer and conventional fertilization, the application of the compound formula fertilizer with high active microorganisms and high nutrient content increased pepper yields by 8.09% and 14.14%, and tomato yields by 11.00% and 14.44%, respectively. In conclusion, the compound formula fertilizer with high active microorganisms and high nutrient content added protectant effectively enhanced vegetable fruit quality, boosted production and income, and improved the economic benefits for farmers.
