How should corn farmers face the ongoing drought in Shandong?

Friends who plant summer corn may encounter such a situation. When corn is sown, the soil is relatively dry due to high temperature and lack of rain. However, during the growth process of the seedling stage, it is still in a relatively dry state, and even reaches In the middle and late stages, it is still relatively dry. In this case, it has a great impact on the growth of corn.

During the growth process of corn, the demand for water is very important. Water shortage at different periods will cause different symptoms, or different effects.

If there is drought from the seedling stage, the corn seedlings will grow slowly and not grow very high. Compared with normal, they will not only be relatively wilted, but also darker in color.

At the bell-mouth stage, if it is relatively dry, it will have a very important impact on the final yield, because the bell-mouth stage is a period when corn needs water and fertilizer. In drought conditions, fertilizer absorption will also be affected.

At the pollination period, if the field is relatively dry, the most direct impact will be on pollination, which will lead to the phenomenon of empty cobs. In previous years, some growers reported that their own corn had empty cobs. Many, a very important factor is caused by drought.

If it reaches the grain filling period and the field is relatively dry, the corn kernels will not be full and the arrangement will not be close, which will directly affect the final yield.

It can be seen from the above symptoms that corn drought has a direct impact on corn yield. What methods can farmers use to remedy this drought situation? Here are 4 points:

1. Irrigation and watering

Water when there is a drought. This is the first method that everyone thinks of. Friends who have the conditions can choose the right time to water. Water, however, according to some farmers, there are no suitable irrigation conditions in the local area. There is no well water or river water around, so it is impossible to water during drought. They usually plant according to the weather. In this case, you can look at the following methods.

2. Apply water outside the roots

When there are no irrigation conditions, water can be sprayed on the roots through a sprayer to alleviate drought conditions, but it is suitable for family growers with small plots. , if you are a large farmer, this situation will require more labor and is not cost-effective. It is recommended here that when spraying water, you can add some foliar fertilizer appropriately to provide some medium and trace elements for the corn.

3. Artificial assisted pollination

If drought occurs during the pollination period and pollination is affected, the yield reduction can be reduced through artificial assisted pollination. For artificial pollination, bamboo poles can be used to catch pollination. , increase pollination opportunities and increase the number of corn cobs.

4. Drought-resistant varieties

The above three points are measures after sowing. Another important method is to purchase drought-resistant varieties before sowing to reduce the risk of drought in drought zones. Under the same external conditions, varieties with stronger drought resistance will be relatively less affected.

The above are the hazards and remedial measures when encountering high temperature and drought weather in the process of planting corn. I hope it can bring some help to everyone.
