What are the remedial measures after banana plants suffer flooding damage?
How do you remedy banana plants after flooding damage? Please explain the methods. Banana plants have fleshy roots with strong respiration and need a loose, well-aerated soil environment. Once they are submerged and waterlogged, the soil lacks oxygen, which causes root rot, and their absorbing capacity declines or is lost, throwing the supply and demand of water and nutrients in the banana plant out of balance; the leaves, stems and fruit cannot get water and nutrients...

Banana plants have fleshy roots with strong respiration and need a loose, well-aerated soil environment. Once they are submerged and waterlogged, the soil lacks oxygen, which causes root rot, and their absorbing capacity declines or is lost, throwing the supply and demand of water and nutrients in the banana plant out of balance; the leaves, stems and fruit cannot get water and nutrients, so not only can they not grow and develop, but severe physiological water loss can also cause them to wither and die. The severity of flooding damage to bananas is related to factors such as the banana variety, the duration of submergence, the banana growth stage, the shade density of the banana plantation, the timing of fertilisation and the type of fertiliser, the type of banana seedling, and the weather after submergence.
Improve the flood control and drainage system of the banana plantation, drain the waterlogged area as quickly as possible, clear the drainage ditches, and shorten the submergence time.
Create environmental conditions that speed up the recovery of root growth. After the disaster, cover the bed surface or the area around the planting holes with banana leaves, rice straw, etc., and in dry weather irrigate and sprinkle water in the morning and evening to keep the soil layer moist. Once the corm has produced new roots, top-dress promptly.
After flooding damage the plants are in poor vigour and are prone to pest and disease damage, so pests and diseases must be controlled promptly. Spray Jiaobanling plus omethoate to control leaf spot disease and aphids, etc., and at the same time spread slaked lime around the base of the banana trunk to prevent fungal diseases of bananas.
After the disaster, clean up the plantation promptly, cut off dead leaves, and cut down plants that have lost economic value, so that suckers grow early and quickly or the plantation can be replanted.
For polder banana plantations with a high groundwater table and near rivers, the embankments must be reinforced, drainage and irrigation ditches and flood discharge sluice gates at all levels must be established, and flood discharge pumping stations must be set up within the polder to drain the accumulated water out of the plantation promptly.
