Technology of banana to prevent cold and pass the winter

Banana is a fruit growing in the tropics, happy warm and wet vegetation, but afraid of low temperature and frost, so the low temperature environment is extremely unfavorable for its growth, but now many growers like to avoid cold damage in the seedling stage Banana planting, so banana buds have to go through cold winter. So bananas in winter if cold? Safe for the winter? Let's take a look at the pro-agricultural network together.

1. Select cold-resistant varieties

When planting bananas, climate and soil conditions should be considered. Some flat and open areas with sufficient light should be selected. Land with deep soil layer, loose soil, good drainage and less frost should be planted. In addition, when planting varieties, it is best to choose cold-resistant, high-yield and stable yield, low seedling stem, strong wind-proof force.

2. Strengthen fertilizer and water management

In winter, winter fertilizer should be applied to improve the soil temperature and enhance the cold resistance of the plant, but winter fertilizer is best not nitrogen fertilizer, nitrogen fertilizer will make the plant grow rapidly, consume nutrients, and the new leaves are too tender green, cold resistance is low. More warm fertilizer should be applied. Such as organic fertilizer and manure and other farm manure, these fertilizers will release a lot of heat when decomposed, can improve the soil temperature, but also timely spray foliar fertilizer, improve the cold resistance of leaves. In watering management, if it is dry and cold weather, water in time to keep the soil moist and increase the soil temperature, while if it is wet and cold weather, drain water in time to protect the root system.

3. Bagging insulation

Bagging and heat preservation method is a common cold protection method. Bananas that cannot be harvested in time in November will be bundled with banana leaves and wrapped firmly with film to prevent moisture from entering the banana stem, while banana fruits that have been extracted will be covered with plastic bags, with warm bags inside and waterproof films outside. Before bagging, we should spray 500 times solution of fruit and vegetable key protection transparent coat, which can not only prevent disease infestation, but also improve fruit quality. When bagging, put a layer of straw paper to avoid direct contact with banana fruit, but also increase temperature and promote normal growth of banana.

4. Smoke in Qingyuan

Before overwintering, all weeds and sundries in the orchard shall be removed, and then straw or dead banana leaves and firewood shall be piled together, and it shall be ignited in cold and low temperature. It is best to ignite it in the evening. When igniting, it shall be noted that the open fire shall not be too large, so that it shall smoke slowly, so that there is a layer of smoke over the whole orchard, which can improve the temperature of the orchard and prevent freezing damage.

The above is the banana cold-proof winter technology brought by the pro-agricultural network. I hope it can help you. If you want to know more about banana planting knowledge, please pay attention to the pro-agricultural network.
