I believe that many people have the experience of being a child. After the corn is ripe, the corn will be dumped and the corn will be picked up from the corn plants and transported home. Another one is that I especially hope to eat empty rods that are not corn, sweet, and like sugar cane. When I was young, I didn't understand things. I was excited to see the empty poles that didn't grow corn for a long time. It is estimated that adults should be uncomfortable when they see the empty rod. Because the corn empty rod will cause a drop in production, but why is there a hollow rod in the corn? Let's take a look at it.

What is the reason for the empty corn pole?

1. Corn varieties

There are many reasons for the emptying of corn, and corn varieties are also a key factor. Some corn varieties have high resistance to empty rods, and the probability of empty rods is small. Some corn varieties have low resistance to empty rods, and the probability of empty rods is high. If the empty rod is severe, it will have a great impact on corn production, which may result in a 30% to 40% reduction in corn production.

2, other reasons

In addition to corn varieties, planting density, fertilizer management, pests and diseases during the pollination are all responsible for the empty poles of corn.

Before planting corn, many people blindly pursue high density and ignore the optimal density for corn varieties. The higher the density of planting corn, the nutrients, water and light will be affected, and the field will be impenetrable, which will affect the normal growth of corn and affect the flowering and pollination of corn.

The common point of the empty stem plants is that the plants and the ears of corn are fine and small, which are caused by insufficient nutrition, insufficient water and pests and diseases. Therefore, during the cultivation of corn, in addition to watering and fertilizing according to the growth characteristics of corn, it is necessary to prevent the occurrence of pests and diseases and increase the growth of corn, which will naturally reduce the probability of corn empty poles.

The temperature is too high or too low during the pollination, and the humidity is too small and too small will affect the pollination rate of corn. During the pollination of corn, such as high temperature and low rainfall, timely irrigation and topdressing should be applied to reduce the temperature in the corn field, and drain in the rainy season. If necessary, increase the artificial pollination work and increase the pollination rate.

The above is the introduction of the corn empty pole. After reading the introduction of Xiaobian, is it that this is justified. Planting corn, naturally hope that it can bring high yield, so we must pay attention to the corn empty pole, the above mentioned the reasons for its emergence, I hope everyone can prescribe the right medicine.
