AI Technical Summary
Existing bio-organic fertilizers have difficulty achieving stable survival and effective colonization of microorganisms in saline-alkali environments, resulting in unstable field effects and failing to meet the comprehensive needs of complex agricultural production environments.
The SK5+NJAU4742 compound microbial agent, including Penicillium SK5 and Trichoderma guizhouense NJAU4742, is used to prepare bio-organic fertilizer by mixing and maturing with decomposed organic substrate. This provides physical protection and a nutrient environment, enhancing the survival and colonization of microorganisms under saline-alkali conditions.
It significantly improves crop emergence uniformity, promotes plant growth and biomass accumulation, and increases crop yield in saline-alkali soils, demonstrating a stable and significant growth-promoting and yield-increasing effect.
