How to deal with the continuous rainy weather in maize seedling stage and reduce losses?

Summer has a unique climate feature, that is, when the temperature is high, there is more precipitation.

However, in many areas, after continuous rainfall, the sown corn seedlings were flooded. So what should corn growers do to reduce losses? Let's have a look.

At present, the planting environment of corn usually chooses field planting. In view of the excessive accumulation of water in the field, no matter whether the precipitation continues or not, it is necessary to ditch and drain in time.

In case of continuous rainy weather, it is necessary to decide the future management according to the specific growth of corn seedlings, as follows:

First, corn seedlings were seriously affected.

Generally, in the continuous rainy weather, the growers' friends did not carry out the drainage work in time, which led to the corn seedlings soaking in water for too long, which would have a serious impact on the dead roots and rotten roots, which basically meant that the corn seedlings were hopeless.

It is suggested that after drying in the field for a period of time, land preparation should be resumed and other crops suitable for local growth should be planted to reduce losses.

Second, corn seedlings have not been seriously affected.

If the corn seedlings are only weak, yellow and weak, the following four points should be done in time:

1, topdressing in time: topdressing is needed in time when the drainage work is completed and manual operation is resumed in the field.

Part of urea can be topdressing to promote the normal growth of corn, and some foliar fertilizer can also be sprayed.

2. Pest control: flooded corn fields are prone to pests and diseases, and the resistance of corn seedlings is greatly weakened after continuous rainfall.

Therefore, during this period, we should pay attention to timely observation and spray corresponding pesticides or fungicides for specific pests and diseases.

3. Weed control: continuous precipitation has little effect on weeds, and some vigorous weeds will greatly affect the growth of corn.

In view of this situation, weeding in the field should be carried out in time after the corn has been loose for a period of time.

4. intertillage management: After the precipitation subsided in summer, it ushered in a sunny day with continuous high temperature. At this time, intertillage management should be carried out in time, the main purpose of which is to prevent soil hardening.

At the same time, weeds in the field can be effectively controlled during intertillage.

The above is the introduction of the coping methods of corn seedlings when they encounter continuous precipitation weather.

Generally speaking, growers should take corresponding measures in time according to the specific growth situation of corn seedlings. If they can prevent it in advance, they should also do a good job of rescue afterwards to reduce losses.
