The reason for the spike of the latest corn

Today, August officially enters, the temperature is also getting higher and higher, and many areas where corn is grown have also entered the final stage of corn coking. But there are also many problems that follow, among which corn has many ears, and how good a plant is is a common problem at this stage. So what is the reason for the spike of corn? Next, the editor will introduce to you.

1. Temperature and humidity discomfort

Corn has a suitable temperature at each stage, for example, the most suitable temperature during flowering is about 26 degrees, and the humidity needs to be controlled at about 80%. Because this will be conducive to maize flowering and pollination, if the temperature is lower than 18 degrees or higher than 38 degrees, the survival rate of pollen will be reduced and the time will be shortened. Humidity below 60% will affect the flowering rate of corn, because the lack of water in pollen will shorten the survival time. If the humidity is more than 90, it is difficult for the pollen to disperse. When it comes into contact with water, it will break and cannot be pollinated.

2. Drought and water shortage

In the case of drought and lack of water, the male ear of maize can not be extracted or the time is too long, resulting in different periods of male and female heading, and it is not easy to pollinate and fertilize. Because there is a great need for water during the heading stage, if there is not enough water, the pollen of the female flower will be dead when the male ear is pulled out. High temperature will also make the female spike develop too late, silking too late, and wait until the end of the pollen spread of male flowers. At this time, there is no male pollen in the corn field, so it is impossible to pollinate and fertilize. Nutrition can not be transferred, downward transfer to stimulate the growth of axillary buds, resulting in the formation of multiple spikes, a multi-stick phenomenon.

3. Disease harm

The phenomenon of multi-spike will also be formed when corn is damaged by diseases and insect pests in the early and middle stages. Eating by diseases and insect pests will lose the growth point of corn, resulting in the top of corn can not grow, nutrition down to stimulate the germination of lateral buds, forming the current situation of many heads and many ears. And some pests also spread some diseases, such as aphids and so on. These pests will carry diseases such as virus diseases, resulting in the production of toxins in corn, the nutritional balance in corn is broken, the top can not grow, and nutrition moves down to make lateral buds germinate. How good it is to form multiple spikes.

4. Fertilizer is unreasonable.

Corn in the growth process needs to ensure its fertilizer and water, can not let corn lack of fertilizer and water, otherwise it will affect the normal growth and development of corn. But if there is too much water and fertilizer, it will also affect the development of corn, which is one of the reasons why corn has many ears. Because if there is too much water and fertilizer, too many nutrients in the corn can not be consumed, lateral buds will be produced and many ears will be formed.

The above four kinds are the main reasons why corn has many ears and is good. Of course, there are other reasons, such as variety, density and so on. Corn multi-spike and multi-stick should be broken immediately, because the multi-spike rod is withered and worthless, but it needs a lot of nutrients, which will grab nutrients with the trunk and affect the development of the trunk.
