Mild Saline-alkali Land Management Model in Xinrong District, Datong City, Shanxi Province

Saline-alkali soil in Xinrong District of Shanxi Province is mainly distributed in the low-lying part of the watershed. Most of them are mild salt and alkali hazards, mainly sulfate and soda salinization. The soil fertility is not high, the soil structure is not good, the surface layer is shallow and other obstacles are more.

Technical model

The model applied soil improvement, fertility cultivation and other comprehensive technology models to improve the quality of cultivated land, including three key technologies, including adding organic fertilizer, applying ferrous sulfate, and applying organic fertilizer.

Key Technical Points

1. Applying organic fertilizer

2. Applying ferrous sulfate

3. Applying organic silicone fertilizer

Technical effect

The average increase in grain per mu is 31.2 kg, and the increase in income per mu is 124.8 yuan. The soil organic matter content was increased, the salt content of cultivated land was decreased obviously, and the quality grade of cultivated land was improved. The physical and chemical properties of soil were significantly improved, the soil compaction was broken, and the water storage capacity of soil was enhanced.
