Banana plants have a water content of more than 80%, and produce 600 parts of banana dry matter. Banana is a herbaceous crop with large stems and leaves and large transpiration. Most of the roots are distributed in the topsoil and are very sensitive to drought and mites. Experts from the Provincial Banana Association said that the banana root is a succulent fibrous root and is aerobic, so it is not resistant to water immersion. When the groundwater level of the banana plant is high and the drainage is poor, the soil water holding capacity is saturated for a long time, which will be severely deprived of oxygen and the root system is under hypoxia. Breathing and suffocating, easy to lead to rotten roots.
Experts suggest that bananas need a lot of water, but they can't be baptized. Therefore, in the cultivation of bananas, attention should be paid to preventing flooding and timely accumulation of water to meet the needs of banana growth and development. After the flood, the water should be removed and the garden should be cleared in time. The baptized banana plant should seize the time to dredge the irrigation and drainage ditch, quickly eliminate the waterlogging in the field and shorten the dipping time. It is necessary to clean up the banana plant in time, cut off the dead leaves, and try to clean the sludge on the leaves of the damaged banana seedlings.
Plants that can still grow normally after lodging are supported by brackets and cultivated well to prevent re-falling. For young fruit and strong fruit plants, most of the leaves are broken or the leaves are blown and filiform, and appropriate amount of fruit should be considered. Remove the broken and fallen stems and leaves in time, and move out of the banana plant to reduce the occurrence of pests and diseases. After the banana is immersed, the plant is poor in potential and vulnerable to pests and diseases. It is necessary to spray the medicine in time.
The banana plantation, which is seriously affected and difficult to resume growth, should be replanted in time. The banana plant with lighter damage can cover the noodles with banana leaves, straw, shading nets, etc., keeping the soil moist and accelerating root growth. After the water immersion, the root growth of the crops is slow to recover. Do not rush to fertilize. Spray one or two times of potassium dihydrogen phosphate, power 2003, Yunda 120 and other foliar fertilizers. After the new roots are issued, grasp the topdressing.
