Technical Model of Salinized Soil Improvement in Shandong Province

Salinized soil in Shandong Province is widely distributed in the alluvial plain of the Yellow River and the Yellow River Delta region, and the salinized soil area of the province is about 8.9 million mu. Because of the special geographical environment of the Yellow River alluvial plain and the Yellow River Delta area, there is always the threat of salinization.

Technical Model

There are engineering measures, agronomic measures and biological measures based on the rich experience accumulated in salinized soil improvement.

Technology Principle

According to the factors restricting the improvement of soil fertility, various basic construction measures of water control and soil improvement should be adopted according to local conditions. On the basis of transforming the soil environment of saline-alkali land, the soil is cultivated and the soil fertility is improved constantly.

Key Technical Points

1.A deep ditch drainage salinity

2. Underground pipe drainage project

3. Flat land

4. High field

5. Choose to plant salt tolerant crops

6. Enriching the soil fertility

Technical Effect

Through land improvement and fertilizer cultivation, the long-term fertility of the soil is improved. The average annual grain increase is 150kg, and the annual income is 390 yuan. Improving farmland infrastructure can improve the efficiency of water supply and expand the irrigated area. It can reduce the groundwater level, reduce the salt content of soil and improve the ecological environment of farmland.
