Anti-freezing measures of sugarcane overwintering

Sugarcane is mostly on the market in spring, but in fact, sugarcane has matured in winter, and it is cold in winter, which is not conducive to listing, so it is listed when the temperature picks up in spring. If it is harvested and stored in winter, if the storage time is too long, it will lead to water loss and decay of sugarcane, so many growers choose to spend the winter in sugarcane fields. However, the low temperature during the overwintering will lead to sugarcane frost damage, so overwintering anti-freezing measures are extremely important, the following pro-agricultural network will bring several anti-freezing measures during the overwintering, let's take a look.

1. Smoking and anti-freezing

When the temperature is low in winter, frost is very easy to occur, resulting in no harvest in the whole sugarcane field. We can achieve temperature rise by smoking to prevent frost damage. Set up a smoke pile in the ventilated part of the sugarcane field to burn smoke when the temperature is low at night and continue until the temperature picks up in the morning, which can generally rise by 1-30 degrees, but it needs to be handled properly, if it produces open fire, it is also extremely harmful, and it is only suitable for sparsely populated, open environment, and has a certain degree of pollution to the environment.

2. Irrigation and anti-freezing

Irrigation and anti-freezing is suitable in arid areas, but not in humid environment, otherwise it will be counterproductive. Proper irrigation in sugarcane fields can not only enhance photosynthesis, but also increase yield and sugar accumulation, increase soil moisture, store heat during the day, and slow the cooling rate of soil at night, which can play a role in anti-freezing.

3. Increase fertilizer application

If the temperature is low in winter, we can find a way to increase the temperature, and fertilization is also a more practical way to apply phosphate fertilizer or thermogenic organic fertilizer before winter, so that the fertilizer will emit heat when it is decomposed, which can not only improve the temperature of the soil and the frost resistance of sugarcane, but also increase the yield.

4. Plastic film mulching

In the sugarcane fields of overnight sugarcane, ridges and soil cannot be opened and loosened before the end of the frost season, so as to avoid frost damage to the roots of sugarcane. If the frost is more serious, the fallen sugarcane leaves can be collected to cover the roots of sugarcane, or directly covered with plastic film, sugarcane leaves can increase and maintain the ground temperature, play the role of anti-freezing.

The above are the sugarcane winter anti-freezing measures brought by the pro-agricultural network, there are many anti-freezing measures for sugarcane, here are just a list of common methods, hope to help you, more agricultural knowledge, please pay attention to the pro-agricultural network.
