Method for rapidly increasing organic matter in saline-alkali land by combining planting and breeding

A method for rapidly increasing organic matter in saline-alkali land by combining planting and breeding, comprising the following steps:

• step 1:
• ploughing and performing a land preparation, then sowing green manure plant seeds with a sowing rate of 8-10 kg/mu;
• during ploughing, applying a soil conditioner, a base fertilizer and 200-300 kg/mu of a homemade organic fertilizer into the soil, at 40-45 days after sowing, applying 30-40 L/mu of a salt-tolerant foliar fertilizer by spraying;
• step 2:
• grazing livestock when a plant height is 40-50 cm, collecting cattle and sheep feces, terminating the grazing when the plant height is 10-20 cm, and resuming when the plant grows to a height of 25-35 cm until the green manure is harvested;
• at harvest, collecting straw for subsequent use, and leaving a root stubble in place at a height of 10-20 cm and applying into the soil;
• step 3, mixing the green manure straw, cattle and sheep feces, calcium superphosphate, ferrous sulfate and composite bacterial agent, fermenting the mixture to obtain a homemade organic fertilizer;
• step 4, rotating green manure crops and continuing to graze livestock.
