How to grow corn in saline-alkali soil

1. Soil improvement

Corn cannot tolerate saline-alkali conditions and will have difficulty growing in such soil for a long time. The plants will become short, the leaf color will become abnormal and dull, and in severe cases, they will die. If you want to grow corn in saline-alkali land, you must first improve the soil. Because the soil contains a high salt content, you must frequently irrigate it with clean water. In addition, deep plowing should be carried out frequently to turn the part with less content to the top.

2. Increase the application of organic fertilizer

Increasing the application of organic fertilizer is also one of the methods. This can change the structure of the soil and inhibit the rise of water and salt. Long-term use of this fertilizer can improve the soil quality.

3. Variety selection

Because different varieties have different growth characteristics, their salt resistance varies. It is best to select the varieties that are most resistant to saline-alkali soil so that growth obstacles can be reduced.

4. Reasonable planting

The sowing time should be delayed, about a week later than that of ordinary varieties. At this time, the temperature is higher, the germination speed is faster, and the time of salt damage is shorter. Because it is difficult for seedlings to germinate in this type of soil, the seeds must be germinated before sowing. Soak the seeds in warm water and wait until they absorb water and swell before sowing.
