This technology uses low-rank coal to prepare supermolecular aromatic carbon AHA saltfixing materials and salt-tolerant complex bacteria, which are combined to form ecological amendment YSW. Through plowing and tilling, ridge tillage-drip irrigation is adopted for vegetables, and field crops are directly broadcasted, achieving in-situ precise improvement, making crop yield and quality in saline-alkali land reach non-saline-alkali land levels.
