The reasons for the bifurcation of corn

Corn always bifurcates when it comes to seedlings. in fact, corn bifurcation is that corn grows tillers. In fact, for crops, tillering is a good thing, tillers will also bear fruit, but corn is different, corn tillers will not bear sticks. So today I'm going to tell you why corn bifurcates.

1. Variety selection

In fact, the variety accounts for a relatively large part of the corn bifurcation, there have been expert experiments have proved that in the same area, temperature, humidity, light and other management factors are the same, the bifurcation of different varieties of corn is also different. Some have no bifurcations, and some have bifurcations of nearly 50%. This is the bifurcation caused by the variety. For example, varieties with thicker leaves are more likely to occur than varieties with thinner leaves. High-growing varieties are less likely to occur than low-growing varieties.

2. Planting density

Corn planting density is also one of the reasons for corn bifurcation, we all know that corn should not be planted too dense, too dense will affect the ventilation and light of the cornfield. But can not plant too thin, if the corn planting is too low, the corn field nutrients will be too much, the quantity is not proportional to nutrients. Corn absorbs too much nutrients, and if you don't use so many nutrients, it will grow bifurcations on the side, and the bifurcation of corn will be very high when the planting density is too thin.

3. Excess of water and fertilizer

Although corn needs a lot of water and fertilizer in the process of growing, if it is excessive, the loss may outweigh the gain. Especially nitrogen fertilizer, many people think that nitrogen fertilizer can promote the growth of corn, corn cob is fat and big, can increase yield. But fertilizing corn is like eating. If you eat too much, you will feel uncomfortable if you eat too much. If you fertilize too much, it will be the same as the planting density is too thin, too much nutrients can not be absorbed, resulting in bifurcations on the side.

4. Dwarfism factor

In the process of corn planting, maize plants may be dwarfed due to early site selection or improper management, diseases and insect pests, excessive use of health control agents, rough shrinkage disease and so on. As a result, a certain plant of corn is much shorter than other corn, but it is still absorbing nutrients, and the plant is unable to grow and grow tall, so it can only grow and bifurcate next to it to form tillers and transfer nutrients.

The above four are the more common causes of tillers, in fact, corn tillers do not need to pay too much attention, because the corn itself is too nutritious to absorb bifurcations. However, if the tiller grows as high as the trunk, the tiller still needs to be removed, because the tiller needs more and more nutrients, which may lead to trunk malnutrition.
