Watering corn after emergence should not be too hasty to avoid choking seedlings.

The corn has just emerged. Can you water it? Science Xingnong believes that if it is dry, it will be watered, but if it is not dry, there is no need to rush to water.

The demand for water of maize is much higher than that of soil, and the root development of maize at seedling stage is poor, so sufficient water supply is needed to ensure the growth and development of seedling stage. Soil properties directly affect the soil water storage and fertilizer conservation capacity, such as sandy soil, it is very easy to drought, for this kind of field of corn, once the lack of water in the seedling stage is also the most vulnerable. Therefore, in terms of watering at the seedling stage, it is still necessary to comprehensively consider the soil and soil moisture at the seedling stage.

Generally speaking, the field should not be watered after corn sowing, but it should also be considered comprehensively according to the soil moisture in the field. Good soil moisture is the premise of realizing the whole seedling, full seedling and strong seedling, which should be considered before sowing, but if the soil moisture is not good, it will inevitably lead to the lack of maize seedlings or unable to complete the seedlings in the field.

For example, the northern part of China is relatively dry and has been short of corn for a long time. For example, this year, the drought in Northeast China has led to the above situation. For this reason, many netizens have asked whether it is possible to water the seedlings when they have just emerged. If you just sow seeds and pour a stubble of masked water, it is very helpful to realize the whole seedling. However, many farmers have missed this opportunity, resulting in uneven seedling stage, at this time, should we recharge water?

Here, it is suggested that the soil water capacity in the field can be measured, and if the amount of water is 60-65%, there is no need to rush to water, because the maize plant at the seedling stage is weak, drought-tolerant and afraid of waterlogging, and if strongly watered, the seedlings may be injured. However, if the water content is too low, it must be watered!

But watering is also skillful, as mentioned above, the seedling plant is weak, so if watering, you need to reduce the amount of water supply, small water flooding or sprinkler irrigation, you can water 40 cubic meters per mu, there is no need to pursue a large amount of water.

The above is a scientific view on whether the corn has just emerged and watered. I hope it will be helpful to you.
