Soil secondary salinization problem solution

In some old vegetable production areas, the proportion of organic matter decreased, and some ion concentrations were high. Due to the interaction between ions, the roots of the plants were difficult to absorb some of the necessary ions for growth, resulting in secondary salinization of the soil.

1. Desalting with water: Mainly relying on flooding salt and ditching to bury the dark pipe. By washing the salt vertically, the brine is washed out through the brine pipe or discharged and concentrated.

2. Biological demineralization: use leisure or crop rotation to cultivate fast-growing salt-absorbing crops such as Sudan grass and corn.

3. Rotation: Carry out the rotation of paddy fields and vegetable fields.

4. Application of organic fertilizer: Some agricultural and sideline products with high carbon content such as rice husk, wheat straw and wood chips can be applied to the soil.

5. Tillage measures: Deep ploughing can be carried out to mix the topsoil and the deep soil moderately so that the ion concentration in the ploughed soil is appropriately reduced.
