Banana Cold-Protection and Wintering Techniques
Banana is a fruit that grows in the tropics, a plant that likes warmth and moisture, but it fears low temperatures and frost, so low-temperature environments are extremely unfavorable for its growth. However, nowadays many growers prefer to plant bananas mainly by avoiding cold damage at the seedling stage, so banana bunch emergence must go through the cold winter. So how can bananas be protected from the cold in winter? How can they overwinter safely? Let's take a look together with Qinnongwang.
1. Choose cold-tolerant varieties
When planting bananas, climate and soil conditions must be considered. Choose areas that are flat and open, with sufficient sunlight, and also require plots with deep, loose soil, good drainage, and few frost occurrences for planting. In addition, the varieties chosen at planting time should preferably be highly cold-tolerant, high-yielding and stable-yielding, with shorter pseudostems and strong wind resistance.
2. Strengthen fertilizer and water management
In winter, apply overwintering fertilizer well to raise soil temperature and enhance the cold resistance of the plants, but the overwintering fertilizer should preferably not be nitrogen fertilizer. Nitrogen fertilizer will make the plants grow rapidly, consume nutrients, and the newly grown leaves are too tender and green, with low cold resistance. More warm-natured fertilizers should be applied, such as organic fertilizer and farmyard manure such as manure water. These fertilizers release a large amount of heat when decomposing, which can raise soil temperature. Foliar fertilizer can also be sprayed at the appropriate time to improve the cold resistance of the leaves. In water management, if the weather is dry and cold, water promptly to keep the soil moist, which can increase soil temperature; if the weather is wet and cold, drain promptly to protect the root system.
3. Bagging for warmth
The bagging-for-warmth method is a common cold-protection method. For bananas that cannot be harvested in time in November, tie up the banana leaves and wrap them tightly with plastic film to prevent water from entering the banana stem. For banana fruits that have already emerged, use plastic bags to cover the fruit, with a warm-natured bag inside and a waterproof plastic film outside. Before bagging, also spray a 500-fold solution of Fruit and Vegetable Preservation Transparent Coat, which can both prevent disease intrusion and improve fruit quality. When bagging, pad with a layer of straw paper to avoid the plastic film directly touching the banana fruit, which can also raise the temperature and promote normal growth of the bananas.
4. Clear the orchard and smoke it
Before overwintering, clear all weeds and debris from the orchard, then pile together rice straw or dead banana leaves, firewood, and the like, and light them during cold and low-temperature periods. It is best to light them in the evening. When lighting, be careful that the open flame should not be too large, so that it slowly produces smoke, forming a layer of smoke above the entire orchard. This can raise the orchard temperature and prevent frost damage.
