If it's the weather

The middle and late stage of maize is a period of strong waterlogging tolerance. Flooding depth of the ground 10 cm, as long as the leaves surface for 3 days, the yield will be greatly affected, although it will not die. Because the growing point of calcaneus has not been exposed to the ground, the yield reduction is the most serious at this time, especially in summer when the temperature is higher and the rainfall is more. If it rains continuously, water will not flow out, corn fields will be soaked by rain, and seedlings will be drowned. In fact, we should "nip in the bud." Before sowing, we should plow the land, make beds and dig drains.

Waterlogging damage is mainly caused by excessive soil moisture, so the first step to alleviate waterlogging damage is to remove field moisture in time, disperse soil moisture in intertillage to increase soil permeability and ensure the normal respiration of plant roots. In continuous rainy weather, we should pay attention to the prevention and control of pests and diseases while doing a good job of drainage. If you encounter drought or lack of fertilizer, the leaves will curl and turn yellow, so you need to topdress and water them in time. When the rainy weather is long, attention should be paid to the wild growth of anthracnose or corn borer and weeds, and corn herbicides can be used to weed and kill insects.

If the rain is not drained in time, the corn seedlings will soon die when the sun comes out. Therefore, in the maize seedling stage, if it rains continuously, we must find a way to drain the rainwater in the maize field, so as not to let the rain soak the maize seedlings. Every time it rains, it must be ensured that there is no obvious water accumulation in the field within 6 hours after the rain stops. Secondly, when the rainy weather ends, the temperature will rise rapidly, and the soil will harden easily, which will affect the growth of maize roots. Therefore,

In view of the continuous rainy weather in the early stage of corn seedlings, we should first pay attention to the phenomenon that corn seedlings are blown down by the wind. Long-term rain will lead to unstable roots of corn seedlings and easy to be blown down by the wind. If maize seedlings lodging in time, it will lead to abnormal growth of maize seedlings. Is there any adjustment? According to the original division, Changzhi is a miscellaneous grain producing area dominated by corn and millet. Meteorologically, this area is called "Southeast Monsoon Climate", which means that it is windy and rainy in spring and is suitable for the growth of miscellaneous grains such as corn and millet.
