How to manage banana after flower stalk removal? Latest technical method tutorial
Banana flower stalk removal means that after the female flowers of the banana begin to set fruit, about 3 flowers will fail to set fruit. At this time, they should be cut off at the tail in time. Reasonable flower stalk removal work can ensure the growth of the fruit. The time for banana flower stalk removal should be chosen on a sunny afternoon, when the sap flow of the banana tree is not strong. The management work after flower stalk removal is very important and affects the growth of banana fruit, so let us take a look at the management techniques after banana flower stalk removal.
1. Apply fruit-fattening fertilizer in time
After banana flower stalk removal, because some nutrients will be lost, attention should be paid to applying an appropriate amount of fruit-fattening fertilizer. The fruit-fattening fertilizer is mainly farmyard manure and phosphorus-potassium fertilizer. After flower stalk removal is completed, each banana tree should be applied with 1 jin of potassium chloride and about 12kg of farmyard manure, and the fertilizer should be mixed and stirred with an appropriate amount of plant ash. Then dig a ring-shaped ditch around the plant, keeping the depth of the ditch at 20cm and the width at about 50cm. After ditch application, cover the fertilizer with soil, pour in enough clean water, so that the fertilizer can dissolve as soon as possible to promote absorption by the plant roots and improve the fertilizer utilization rate.
2. Promote root growth
When applying the fruit-fattening fertilizer, we can directly spread soil-organic fertilizer or soil on the banana tree beds for earthing up. The amount used per tree should be kept at about 45kg, and the thickness should be controlled at about 10cm. Then spread the ditch soil dug out earlier onto the pond sludge or soil-organic fertilizer. About 5 cm is enough to ensure that the roots can absorb sufficient nutrients and promote the growth of bananas. It can also improve the soil's water and fertilizer retention, and its protective effect on the roots is also relatively large. It can enhance the absorption capacity of the roots and avoid the phenomenon of plant growth decline and death.
3. Foliar topdressing
After banana flower stalk removal, we should also do a good job in foliar topdressing. Generally, foliar fertilizer is sprayed once a week, and the foliar fertilizer is mainly urea and potassium dihydrogen phosphate. When spraying foliar fertilizer, ensure that the spraying is thorough and uniform. It is advisable to spray until water droplets drip from the top growth point of the plant. Only in this way can sufficient nutrients be effectively provided to banana leaves and fruit. Promote the expansion and coloring of banana fruit, and avoid the phenomenon of yellow leaves, which would affect the yield and quality of bananas.
4. Reasonable watering
After banana flower stalk removal, attention should be paid to watering well to ensure that the plant does not lack water, and to avoid the bed surface cracking due to water loss and drought. The bed surface should often be kept moist, so we should pay attention to observing weather changes. If drought occurs, then attention should be paid to timely watering. But also be careful to control the amount of watering, and do not water too much, to prevent water accumulation, which would cause dead roots and root rot in banana trees. This would affect the roots' ability to absorb nutrients and water, and hinder the growth and development of bananas.
The above is a brief introduction to the management techniques after banana flower stalk removal. That is all for today's introduction. This article is for reference only, and I hope it can be helpful to everyone.
