Detailed Explanation of Key Sugarcane Management Techniques in Autumn
Today is the Start of Autumn, which also means that autumn is approaching. Autumn is an important stage for sugarcane growth and is quite important for sugarcane development. It is also a key point for increasing sugarcane yield, so doing a good job of sugarcane management in autumn plays a vital role in the quality of sugarcane growth. So how exactly should sugarcane be managed correctly in autumn? Let's take a look together below.
1. Water and Fertilizer Management
Autumn is the key time node for determining the final yield of sugarcane. If high temperature and drought occur during this period, deep plowing and irrigation of the soil should be carried out at most once every 10 days. The soil water content from the surface down to a depth of 40-60 cm should be kept at a minimum of 80%. The fertilizer demand during this period also increases greatly. Fertilize according to the soil conditions and sugarcane growth. If yellowing leaves are found, timely spray a tail-strengthening fertilizer. Determine the amount of fertilizer based on the land area, with about 30 jin per mu. Do not apply too much nitrogen fertilizer, otherwise it will be counterproductive and reduce yield.
2. Disease and Pest Control
Autumn is also a season with a high incidence of many diseases and pests, such as aphids, borers and so on. If aphid and borer pest damage is severe, based on pest monitoring and forecasting, aerial spraying equipment can be used for concentrated control by spraying pesticide from the air. Dispersed control can also be carried out by using pirimicarb diluted with water to spray and kill aphids. Use chlorantraniliprole suspension concentrate according to the instructions for borers. For sugarcane fields with severe diseases such as pokkah boeng, promptly remove the diseased plants, burn the old leaves of diseased plants in a centralized manner, and keep only healthy plants in the field.
3. Wind Protection and Disaster Reduction
Sugarcane is mostly planted in coastal areas, and this year coastal areas have suffered a large number of typhoons, with severe typhoon damage. This period is also exactly the stage when typhoons are most prevalent, so attention should be paid to doing a good job of wind protection in sugarcane fields and minimizing disaster losses as much as possible. Pile soil high to stabilize the center of gravity of the sugarcane, with a soil mound at least 25 cm high at the base of each sugarcane plant. After the typhoon, promptly lift up the lodged sugarcane, tie adjacent sugarcane together with rope to form an "inverted V" shape, and restore normal sugarcane growth as soon as possible.
4. Drainage and Waterlogging Prevention
Typhoons will definitely bring a large amount of rainfall. Although sugarcane likes water, it is a crop that is not tolerant of waterlogging. Before the typhoon arrives, drainage ditches in the field should be prepared. This prevents waterlogging damage to sugarcane caused by rainfall lasting too long and making manual drainage impossible. After the typhoon rainfall stops, the accumulated water in the field should be drained quickly immediately, and the land should be plowed once to strengthen soil permeability. Fertilize in a timely manner, because accumulated water will carry away a large amount of the water in the soil, and this stage is when fertilizer levels are at their lowest.
The above are the methods for managing sugarcane well in autumn. Sugarcane grows relatively tall and is prone to lodging when exposed to wind. After lodging, it will have a relatively large impact on the yield and quality of sugarcane. Therefore, special attention should be paid to this point, and the fact that sugarcane likes water but is not tolerant of waterlogging also needs attention. Many friends think that sugarcane has a large water demand, so they do not manage the accumulated water in the field, which ultimately causes all the sugarcane roots to rot.
