AI Technical Summary
Existing corn coating agents cannot effectively alleviate salt and alkali stress when applied to saline-alkali land, resulting in low seed germination rates and poor seedling growth. Furthermore, they do not fully consider the soil characteristics of saline-alkali land and the growth needs of corn.
Using a multi-acrylate copolymer emulsion as the coating base, combined with novel biostimulants and biochar, a breathable and water-retaining film is formed, which isolates salt and alkali ions, promotes root development and seedling growth, and enhances stress resistance.
It significantly improves the emergence and seedling vigor rates of corn in saline-alkali soil, enhances growth conditions, adapts to saline-alkali soil environments, and is easy to operate and environmentally friendly.
