What about corn lodging?

Corn is a long-stalk crop, although the root system is deep, but with a little external effect, the corn will lodge. After lodging, it is generally difficult to support it, which directly affects the yield. Therefore, lodging must be avoided, and timely and correct operation is needed after lodging. Try to recover the loss. Let's take a look at the causes of lodging and the ways to prevent and improve it.

1. Flood lodging

Because the flood lodging is not uncommon, some fields in the valleys, which are low-lying and close to the river, are easy to be washed down after the summer flood, generally because the whole plant loses after the soil of the root system is washed by water. The root system is turned out of the soil. Such a situation can be picked up from the lodging direction, and then re-cultivate the soil. After timely drainage, change the loose soil and distribute water as soon as possible, but pick it up on the day of flushing.

2. The influence of strong wind

If it is caused by extreme weather, such as windy days, the general situation may be stem lodging, that is, the root system, the base of the stem is not broken, but the upper part of the stem is deformed and cannot be automatically restored for a while. This should be able to slightly help up, support each other, or set up a support. Growth will resume in a short period of time. If it is blown off, it generally needs to be unplugged, and the firm one can be retained after folding.

3. Rainstorm lodging

Because the heavy rain presses the plant and scours the ground soil, the top-heavy stem is easy to bend, but it generally does not lodge from the root. As long as you shake off Rain Water, float up and cultivate some soil under your feet, it will recover in a few days when the weather clears up. Shake the water early and go as soon as the rain stops, otherwise, the backlog will be long and the situation will be aggravated. Shake the water gently with a bamboo pole, do not damage the leaves.

4. Strengthen the management

After lodging treatment, topdressing phosphorus and potassium fertilizer is needed to help growth recovery. In addition, it is easy to get sick after lodging, so we should pay attention to the prevention and control of corn leaf spot and leaf spot, and spray with 50% carbendazim 500 times solution. Use it once a week and use it several times in a row to see the effect. Corn borer is easy to break stem lodging and focus on prevention and control.

In general, lodging often occurs in corn, the reasons may be inconsistent, but the result is the need to improve and save. Sometimes consolidating growth ahead of time is also the best prevention.
