[0016] The present invention uses cation exchange resin to neutralize cations in the soil, uses phosphorus and potassium dissolving bacteria to maintain the soil aggregate structure, and uses polyvinyl alcohol to retain water, thereby achieving the effect of improving saline-alkali land. The use of Bacillus subtilis can have a good effect of degrading potassium in the soil, and releases soluble potassium elements and trace elements such as calcium, sulfur, magnesium, iron, zinc, molybdenum, and manganese. That is, it improves soil fertility, promotes the formation of soil aggregate structure, prevents soil compaction, destroys soil capillary phenomena, prevents soil water evaporation, greatly improves soil fertilizer efficiency, and thus activates the soil. The use of cow dung is a high-quality organic fertilizer that contains rich organic matter and nutrients, such as nitrogen, phosphorus, potassium, humus, etc. The use of cow dung fertilizer can increase soil fertility, improve soil structure, and promote plant growth and development. The use of potassium dihydrogen phosphate can make the soil weakly acidic, which can promote the dissolution of iron elements in the soil, which will be beneficial to the absorption of iron by the plant root system. The use of limestone can improve soil structure, increase soil pH value, promote plant growth, increase soil fertility, etc.

[0017] Specific implementation comparative example: 120 peppers, tomatoes and corns were selected respectively, and the fertilizer of the present invention and the existing common fertilizer were used respectively, and the fertilizers were applied for 20 days.
