Corn can't stand salt and alkali, it will be difficult to grow in such soil for a long time, the plant will become short, the leaf color will not be normal, it will become dull, and in serious cases, it will die. If you want to plant corn in the saline alkali soil, you must first improve the soil quality. Because the soil has a high salt content, you should often wash it with clean water. In addition, we should often plough deeply and turn over the part with less content.
Increasing the application of organic fertilizer is also one of the ways to change the structure of the soil, can inhibit the rise of water and salt, long-term use of this fertilizer, can change the soil quality.
Because the growth characteristics of different varieties are different, so the salt resistance is not the same. It is better to select the most salt resistant varieties, so that the obstacles to growth can be reduced.
The sowing time should be delayed, about one week later than the general varieties. At this time, the temperature is higher, the germination speed is faster, and the time of salt damage is shorter. Because in this kind of soil, it is difficult to sprout. Before sowing, we need to speed up sprouting, soak the seeds in warm water, and then sow them after water absorption and expansion.
