AI Technical Summary
Existing soil improvement technologies for saline-alkali land have limited effectiveness, high costs, and poor stability, making it difficult to achieve large-scale and standardized application. Furthermore, they have failed to be organically integrated with the green ammonia production industry chain, resulting in insufficient economic viability.
A ternary synergistic mechanism of green ammonia-biochar-humic acid is adopted. By precisely controlling the pyrolysis temperature, mixing speed and time of biochar, granular soil conditioner is prepared, and an intelligent monitoring system is used to dynamically adjust the application parameters.
It significantly improved the soil improvement effect of saline-alkali land, with soil pH value decreasing by 0.3-0.5, water retention rate increasing by 10-12.8%, corn yield increasing by 6-9.6%, cost decreasing by 25%, and improvement effect stability increasing by 40%, achieving a four-dimensional integration of ecological restoration and high value-added agriculture.
