Key points of Sugarcane Management in Autumn

Today is the Beginning of Autumn, which also means that autumn is coming. Autumn is also an important stage for the growth of sugarcane, which is more important for the growth of sugarcane. It is also an important node for sugarcane to improve sugarcane yield, so the management of sugarcane plays a vital role in the growth quality of sugarcane in autumn, so how to manage sugarcane correctly in autumn? Let's take a look at it with the editor.

1. Water and fertilizer management

Autumn is the key time point for the final yield of sugarcane. If there is a high temperature and drought in this period, the soil should be irrigated once every 10 days. The distance between the soil surface and underground 40-60cm should be kept at a minimum of 80% of the soil water content. The fertilizer demand in this period is also greatly increased, according to the growth of soil and sugarcane corresponding to fertilization, if found that the leaf yellowing situation should be timely spraying strong tail fertilizer, according to the land area to determine the amount of fertilizer, the amount of fertilizer per mu is about 30 jin. Do not have too much nitrogen fertilizer, otherwise it will be counterproductive and reduce the yield.

2. Disease and pest control

Autumn is also a season with high incidence of many diseases and insect pests, such as aphids, borer and so on. If the occurrence of aphid borer pests is serious, the centralized control treatment can be carried out by using air spraying equipment to carry out pesticide spraying in the air according to the prediction of insect situation. Decentralized control can also be carried out and aldicarb mixed with water can be used to spray and kill aphids. Use chlorobenzamide suspension against borers in accordance with the requirements of the instructions. For sugarcane fields with serious diseases such as tip rot, the diseased plants should be pulled out in time, the old leaves of diseased plants should be burned, and only healthy plants should be left in the field.

3. Wind prevention and disaster reduction

Many kinds of sugarcane are located in the coastal areas, but this year the coastal areas have suffered a large number of typhoons, which have caused serious damage. This period of time happens to be the most popular stage of typhoons, so we should pay attention to the wind prevention work in sugarcane fields and minimize the disaster as far as possible. Make the mound high and secure the center of gravity of sugarcane. Under each sugarcane, there is a mound at least as high as 25cm. The fallen sugarcane is picked up in time after the typhoon, and the adjacent sugarcane is tied up with a rope to form a "in" shape to restore the normal growth of sugarcane as soon as possible.

4. Waterlogging and waterproof

Typhoons are bound to bring a lot of rain. Sugarcane is a water-loving but intolerant crop. The drains in the field should be prepared before the typhoon. The prevention and control of precipitation for too long can not be artificially drained, resulting in waterlogging damage to sugarcane. After the typhoon stops raining, the stagnant water in the field should be discharged quickly and the land should be ploughed again to enhance the permeability of the soil. Fertilize in time, because stagnant water will bring a large amount of water out of the soil, this stage is the least amount of fertilizer.

The above is how to manage sugarcane in autumn, sugarcane grows taller, lodging is easier in case of wind, and lodging will have a greater impact on the yield and quality of sugarcane. Therefore, we should pay attention to this point, and it is also necessary to pay attention to the fact that sugarcane is not resistant to waterlogging. Many friends think that sugarcane needs a lot of water, so it will not manage the stagnant water in the field, which eventually leads to the rot of all the roots of sugarcane.
