What about sugar cane lodging?

As a kind of fruit with high sugar content and high nutrition, sugarcane is deeply loved by many people. As we all know, the average height of sugarcane is about 2 meters, and there must be many problems to be faced in the process of growing so tall, among which lodging is a more common problem of sugarcane. So why does sugarcane lodge? What should I do when sugarcane loses down? Let's take a look at it with the editor.

I. the reasons for the lodging of sugarcane

Sugarcane is a relatively tall crop, it can reach more than two meters in the later stage, the plant is tall, and the leaves will increase with it. If you encounter rainstorm and storm weather, the center of gravity is unstable and it is easy to fall down. Especially after the rain, the water in the ground causes the tail to become heavier, and the wind will lodge when the wind blows gently. After lodging, the part that touches the ground may grow new roots, sprout on the side, and the whole sugarcane will become bent, consuming nutrients in the trunk. Causes the sugarcane to dry up the space, the development is stunted.

Second, the influence of sugarcane lodging

1. After a large area of sugarcane lodging, the sugarcane leaves will overlap, resulting in the leaves inside unable to carry out photosynthesis, making the leaves withered and yellowed.

2. The lodging of sugarcane will break the rhizome and hinder the absorption and transport of nutrients in sugarcane, resulting in insufficient nutrient development of sugarcane stem and withered hollow.

3. Lateral buds will grow after lodging, and a large number of lateral buds will sprout and grow, robbing the dry sugarcane of nutrients. As a result, there is less sucrose in the dried cane, which in turn reduces the dry weight of the cane.

4. Rodent damage and cotton aphids are most likely to occur after lodging, they will gnaw on sugarcane, resulting in sugarcane damage and growth, and after lodging will break the root and affect the planting of the next year.

III. Prevention and control of sugarcane lodging

The main results are as follows: 1. When selecting varieties, we should choose this lodging-resistant variety, which is mainly because the cane stem is relatively hard, the root is very strong, and there are not many sugarcane leaves in the later stage, and the cane stem is straight and not easy to lodge.

2. Base fertilizer should be fully applied before planting, and topdressing will be done as soon as possible. It is necessary to prepare fertilizer reasonably and not apply more nitrogen fertilizer, so that sugarcane can grow sturdily and improve the ability of lodging resistance.

3. After the sugarcane grows tall, the lower old leaves and dead leaves can be removed, because the photosynthetic capacity of the old leaves has decreased a lot, and only 5-8 leaves are needed for each sugarcane plant. This can reduce the load-bearing and wind-exposed area of sugarcane and prevent lodging. The sugarcane can also be tied into a "human" shape with a rope when the sugarcane is about two meters long, which can also effectively prevent lodging.

The above is the brief introduction of the reasons and prevention of sugarcane lodging. Sugarcane lodging will directly affect the quality and yield of sugarcane. Everyone should take precautions in advance to avoid lodging. If there is a lodging, I hope this article can help you.
