How to prevent banana fruit cracking? Practical prevention and control measures shared
In the late stage of banana fruit development, the peel is highly prone to longitudinal splitting; after rain, the cracks rot, while in dry climates the peel near the cracks shrinks and dries. It also invites pests and diseases, seriously affecting fruit yield and quality and causing huge economic losses. So how should banana fruit cracking be prevented? Let's take a look at the detailed introduction below.
1. Strengthen fertilizer and water management
The main cause of banana fruit cracking is climate change; for example, when a long drought is suddenly followed by rain, the flesh rapidly thickens after absorbing too much water, and the peel cannot keep up with the flesh's growth rate, bursting under the pressure of the flesh. Therefore, management should be strengthened in the late growth stage of bananas. After the banana emerges from the bud, increase the application of farmyard manure or organic fertilizer to improve soil structure, making the soil loose and fertile, promoting root growth, strengthening the tree vigor and improving disease resistance. During fruit development, in case of drought, water once every 3-5 days to keep the soil moist, and at the same time pay attention to the application of phosphorus and potassium fertilizers to ensure sufficient nutrients.
2. Foliar fertilization
After the banana bud is removed, the demand for nutrients is relatively high, and the absorption capacity of the roots of some plants cannot keep up with what their growth requires; therefore, to promote their growth, foliar spraying should be adopted. Generally, spray foliar fertilizer once every 7-10 days; you can use Jiaodabao 700-800 times dilution or polymucleotide 200 times dilution, or high-efficiency foliar potassium Lvfengsu 1000 times dilution, to promote fruit development.
3. Bagging
During the fruit development period, inspect frequently; if fruit cracking is found, promptly cut off the cracked banana hands and dispose of them centrally to prevent further cracking. To reduce the occurrence of fruit cracking, when the young banana fruit turns upward and the hands separate, you can use special banana bags to cover the banana bunch well, which facilitates fruit development and has a good effect on preventing fruit cracking.
4. Timely harvesting
Bananas also crack when overripe, so at maturity, fruit for distant sales should generally be harvested at 70-80% ripe, while fruit for local sale can be harvested at 80-90% ripe. This avoids severe fruit cracking when bananas are overripe and reduces losses.
