Causes and Preventive measures of Sugarcane lodging

In the process of planting sugarcane, farmers often encounter the phenomenon of sugarcane lodging, which is extremely disadvantageous to the growth of sugarcane, and there may be a large area of dead plants. So what is the cause of sugarcane lodging? Let's get to know it with the editor.

1. The cause of sugarcane lodging

In the middle and later stage of sugarcane elongation, the plant is tall and has more leaves, so if it is attacked by wind and rain, it is easy to lodge for a long time. Especially when the sugarcane tail accumulates too much water after rain, it will lodge in case of wind. after the sugarcane lodging, its stem nodes near the ground are very easy to sprout, sprout lateral buds, making the originally upright stem become curved, and because the nutrients of the internodes are consumed in large amounts, resulting in hollow or bushy rows. This will result in a serious reduction in sugarcane production, sugar content decline, resulting in persistent root dysplasia, will also have a great impact on the following year's planting.

2. The effect of sugarcane lodging

After lodging, the leaves of sugarcane will overlap each other, resulting in a reduction in the area of photosynthesis, so that the synthesized nutrients are very few, and after lodging, its rhizome will be damaged or directly broken, so that the absorption and transport of nutrients in the root system will also be hindered, and it is very easy to form hollow and puxin, so sugarcane has no commercial value. And after lodging, stem nodes will germinate a large number of aerial roots, resulting in a large number of lateral buds germination and growth, which will lead to a substantial decrease in sugar content of sugarcane, resulting in a serious reduction in yield. And because after lodging, the leaves cover the ground, which creates the best place for diseases, insect pests and rodents, and the breaking of the root system will affect the germination of persistent roots in the following year.

3. Preventive measures

When selecting varieties, the varieties with strong wind resistance and lodging resistance should be selected, the soil blocks with back Phoenix and sunny soil should be selected in the hilly areas of the heart, and the windbreak forest belts should be planted in the plain areas, which can greatly prevent lodging due to strong winds. When planting, we should adhere to deep ploughing, and appropriate deep planting, which can promote the root system to go down and enhance the lodging resistance of the plant. Reasonable fertilization, no partial application of nitrogen fertilizer, reasonable combination of nitrogen, phosphorus and potassium fertilizer, in order to enhance the toughness of sugarcane fruit, timely soil cultivation, appropriate increase of soil height. It is necessary to drain and reduce the water level in time after the rain, which can lead to deep binding and multiple occurrence of the root system. Before the windy weather, sugarcane can be stripped and bundled, and the adjacent three or five rows of sugarcane can be tied into a herringbone bundle to enhance the support between each other. Straighten the fallen sugarcane in time after the wind, step on the soil at the same time, and apply a small amount of nitrogen fertilizer in time.

The above is the introduction of the causes and preventive measures of sugarcane lodging. I hope it can help you. If you want to know more about it, please follow us.
