Detailed Explanation of the Latest Technical Points for Sugarcane Management in Autumn
Today is the Beginning of Autumn, which also means that autumn is about to arrive. Autumn is also an important stage for sugarcane growth and is quite important for the growth of sugarcane. It is also an important point for increasing sugarcane yield, so doing a good job of sugarcane management in autumn plays a vital role in the growth quality of sugarcane. So how exactly should sugarcane be managed correctly in autumn? Let's take a look together with the editor below.
1. Water and fertilizer management
Autumn is the key time point that determines the final yield of sugarcane. If high temperature and drought are encountered during this period, deep plowing and irrigation of the soil should be carried out at most once every 10 days. The soil moisture content from the surface down to a depth of 40-60cm should be maintained at a minimum of 80%. The fertilizer requirement also increases greatly during this period. Fertilize according to the soil and the growth condition of the sugarcane. If yellowing of the leaves is found, timely spray the tail-strengthening fertilizer. The amount of fertilizer applied should be determined according to the land area, with about 30 jin per mu. Do not apply too much nitrogen fertilizer, otherwise it will have the opposite effect and reduce the yield.
2. Disease and pest control
Autumn is also a season with a high incidence of many diseases and pests, such as aphids and borers. If aphid and borer infestations occur severely, according to pest monitoring and forecasting, aerial spraying equipment can be used to carry out chemical spraying in the air for centralized control. Dispersed control can also be carried out, using pirimicarb mixed with water to spray and kill aphids. Use chlorantraniliprole suspension concentrate according to the instructions to target borers. For sugarcane fields with severe diseases such as pokkah boeng, promptly remove the diseased plants, burn the old leaves of the 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 reducing the disaster situation as much as possible. Pile soil high to stabilize the center of gravity of the sugarcane, with each sugarcane having an earthen mound at least 25cm high at its base. After the typhoon, promptly lift up the lodged sugarcane, tie adjacent sugarcanes together with rope to form a "" shape, and restore the normal growth of the sugarcane as soon as possible.
4. Drainage and waterlogging prevention
Typhoons will inevitably bring a large amount of rainfall. Although sugarcane likes water, it is not tolerant of waterlogging. Before the typhoon arrives, the drainage ditches in the field should be prepared. This prevents waterlogging damage to sugarcane caused by rainfall lasting too long and the inability to drain water manually. 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 the permeability of the soil. Fertilize in time, because accumulated water will carry a large amount of nutrients out of the soil. This stage is when the fertilizer amount is at its 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 because sugarcane has a large water requirement, they do not manage the accumulated water in the field, which ultimately causes the entire root system of the sugarcane to rot.
