Some parts of China suffered heavy rains some time ago, and many food crops were damaged. Recently, many corn growers have asked the corn to be flooded. What should I do? What should I do if the corn seedlings are flooded?
1. Can the corn seedlings be flooded for more than a few days and cannot live?
In general, if the water is immersed for more than three days, it will seriously affect the root system's absorption of nutrient function, resulting in yellowing of the plant, leaf wilting, photosynthesis weakened or stopped; if the soaking continues, the root system cannot perform normal respiratory function, which will result in The roots rot and eventually cause the whole plant to die. Therefore, the clear water should be eliminated in the first place, and the surface should be dilute and dehumidified in time.
Second, what are the hazards of corn being flooded? How to avoid production cuts?
1. Harm the root system, leaf development, timely drainage
When the corn seedlings are flooded, it will definitely affect the development of the corn roots and the development of the leaves, so timely drainage is very critical.
2. Prone to grass shortage, timely weeding
After the flooded corn field, after the water is removed, due to the soil weight, it is unfavorable for cultivating, and it is very easy to occur. After the weather is fine, the field weeds should be removed in time by chemical or artificial means to avoid competition with corn for nutrients.
3. Easy to cause fertilizer loss, timely fattening
Due to the soaking of water, the fertilizer in the corn field is seriously lost due to dissolution, and it is necessary to supplement the fertilizer. Otherwise, the problem of de-fertilization is easy to occur. At this time, the time and severity of the flooded land should be combined to determine the amount of fertilizer, combined with the application of arable farming to ensure Normal fertilizer supply.
4. Prone to pests and diseases, timely prevention
After flooding of corn seedlings, due to poor function of leaves and roots, the plants are weak, the immunity is reduced, the disease resistance is poor, and they are more susceptible to diseases and pests. At this time, measures should be taken in time to combine local susceptible diseases and pests. Spray the corresponding agent to prevent the occurrence of pests and diseases.
In general, the corn seedling stage is greatly damaged by flooding. If it is not treated in time, the production will be reduced, but the production will be severely produced. It must be highly valued and treated in time to avoid production cuts.
