How to manage bananas during the shooting stage? These key points you need to master
When bananas enter the shooting stage, their vegetative growth and reproductive growth advance side by side, and management at this time is extremely important. Even a small mistake can seriously affect yield and quality. So how should bananas be managed after entering the shooting stage? Come and take a look at the detailed introduction below with the editor.
1. Fertilization
Bananas need a large amount of nutrients when shooting, so fertilizer should be applied in time before and after shooting. Conventional fertilizers are mainly nitrogen, phosphorus and potassium, but the amount of nitrogen fertilizer applied should be reduced, especially nitrate nitrogen, to avoid excessive vegetative growth that delays shooting, or flower drop after shooting. In addition, bananas are a high-potassium plant, and during the shooting stage flower bud differentiation must be promoted, so boron and zinc should be supplemented to promote root growth and development and improve root absorption capacity. At the same time, calcium and phosphorus should be maintained to promote the growth of young fruit.
2. Flower bud adjustment and flower removal
Flower bud adjustment refers to moving the flower bud growing on the petiole away from the petiole to reduce its resistance, so that the flower bud can grow downward and develop better. Before flower removal, flower wiping is needed. When the flower bud turns black, the flowers on the fruit hands should be wiped off, so that after the flowers fade, the sap that flows out will not drip onto the fruit and affect the fruit's appearance and variety. After flower wiping is completed, the flower can be removed. When 2 to 3 hands of flowers do not set fruit after fruiting, cut off the tail part of their flower buds. Along with short flower removal, fruit thinning is also carried out. Generally, the fruit at the tail of the bunch should be cut off, leaving 1-2 to grow, to prevent the fruit axis from rotting upward.
3. Pest and disease control
During the banana shooting stage, a large amount of nutrients is consumed, and the plant's resistance declines. At this time, there is sometimes a high-temperature and high-humidity environment, which can easily cause pests and diseases, so pesticides should be sprayed in time before and after shooting to prevent pests and diseases. In order to improve the plant's disease resistance, when spraying pesticides, micronutrient resistance can be added to improve the plant's own immunity and disease resistance.
4. Waterlogging prevention
Bananas have a fleshy root system, and during the shooting stage they have relatively strict water requirements. The soil must be kept moist so they have sufficient water for growth, but they are also afraid of overly wet soil or water accumulation, which can cause root rot. The shooting stage is exactly a period with more rain, so drainage measures should be taken well to avoid water accumulation that causes root suffocation and rot and affects growth and development. After rain, take measures such as digging trenches for drainage. Organic fertilizer can also be applied to supplement soil organic matter, improve soil structure, and promote root growth.
