1、 Soil improvement
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 is abnormal, and it will become dim and dull. In serious cases, it will die. If you want to plant corn in saline alkali land, you must first improve the soil quality. Because the soil contains high salt, you should often irrigate it with clean water. In addition, we should often plough deeply and turn over the part with less content p>
2、 Increase the application of organic fertilizer
Increasing the application of organic fertilizer is also one of the methods, which can change the soil structure and inhibit the rise of water and salt. The long-term use of this fertilizer can improve the soil quality p>
3、 Variety selection
Because different varieties have different growth characteristics, they have different salt resistance. It is best to select the varieties that are most resistant to saline alkali land, so that the obstacles to growth can be reduced p>
4、 Rational 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 to sprout in this soil, it is necessary to promote germination before sowing, soak the seeds in warm water, and wait until they absorb water and expand before sowing p>
