Bananas are like hot and humid, afraid of low temperature, bogey frost. Low temperature and dryness in winter are unfavorable for the growth and development of bananas. To do a good job in the management of the winter banana garden and to promote the healthy growth of the banana plant is an important part of ensuring the safe wintering of the banana plant and capturing the high quality and high yield of bananas of the year and the following year.
First, fertilization and soil cultivation in the winter banana garden fertilization should pay attention to increase the application of phosphorus and potash fertilizer, grass ash, fire soil and fully decomposed refuse such as thermal fertilizer. Fertilization time is appropriate before and after the beginning of winter in early November, combined with the spraying of high-potassium-type Gaole or Green-wang No. 1 or potassium dihydrogen phosphate and other high-potassium foliar fertilizer, spraying once every 7 days. , spray 2-3 times. Should be combined with the winter banana garden ditch for surface soil, the thickness of 5 cm is appropriate.
Second, moisture management in winter low temperature dry, banana strains susceptible to cold due to lack of water. Therefore, the banana garden should be well-watered ditch (especially dry land banana plantation) for irrigation and water storage, often maintaining a shallow water layer in the gutter and wet surface, in order to increase the soil temperature and humidity in the orchard, the banana plant warm and cold effect.
Third, the surface of the sorghum and pseudo-stem cover the surface of the banana leaf, rice straw or plastic film covering the sacral soil, so as to protect the saccharin and its roots from cold and promote good root growth. For banana plants with a height of 1.0m or less, the leaves should be bundled to protect the heart and leaves before the frost comes. The frost will be unwrapped after frost. For banana plants with a plant height of 1.5 meters or more, banana leaves or straw should be covered at the base of the heart and leaves of the pseudostem to reduce frost damage.
IV. Ears Bagging For the ear that is about to break buds, the insect should spray the insecticide bactericide evenly once every 15-20 days after bud breaking. The commonly used insecticide is 10% imidacloprid WP 1000 times. 80% dichlorvos EC 1000 times, 40% Dimethoate EC 1000 times, 10% Beta-cypermethrin EC 3000 times etc.; 70% chlorothalonil WP 800 times, 40% polysulfide suspension 400 times Liquid, 12.50% Myclobutanil EC 800 times, 50% Propilotine WP 1000 times and so on. The agents should be used interchangeably to increase efficacy. After the second spraying of the ear, the bag should be bagged. The tail leaves should be placed on the fruit shaft. Then the white woven bag should be used to wrap the ear (including the fruit axis and the tail leaf), and then put on the light blue film bag ( 1.2 meters long, 0.75 meters wide, and 0.03 mm thick. The upper end of the bag is fastened at the bend at the top of the fruit shaft, and the lower end of the bag opens naturally.

Smoke protection, cold protection and water spray, frost frost should be timely to do a good job banana garden smoke, can be used chaff, sawdust, straw, weeds and dried banana leaves, etc. as smoke material, add appropriate amount of waste oil to ignite, in the banana garden In the windward place, a pile of light is ignited every 7-10 meters, so that a smoke layer forms over the entire banana plantation. It is best for all banana farmers to act together. After the frost had passed, spray the frost deposited on the recesses of the banana leaves and petiole in a timely manner with a high-pressure sprayer in the early morning hours to avoid frostbite.
6. Insect pest control Weevil weevil can be connected at the base of the petiole and the pseudostem at the groove, in the evening of the sunny day with 50% dichlorvos EC 800 times or 25% insecticide double water 400 times perfusion, but also in the old leaves Apply a small amount of 3% miral granules on the petiole to kill insects. For newly harvested banana plants, the bud should be sprayed with an insecticide in time to prevent flower buds, spray once every 7-10 days, and spray 2-3 times. For the prevention and treatment of damage to the ear and rodents, it is recommended to use towns or villages as the unit. The medicines can be used for bromadiolone or rat poison, and the ear can be bagged.
