Detailed Explanation of the Latest Management Key Points During the Banana Bunch Emergence Stage
When bananas enter the bunch emergence stage, their vegetative growth and reproductive growth advance side by side, and management at this time is extremely important. The slightest carelessness will seriously affect yield and quality. So how should bananas be managed after entering the bunch emergence stage? Let's take a look together with the editor at the detailed introduction below.
1. Fertilization
Bananas require a large amount of nutrients during bunch emergence, so fertilization should be carried out promptly before and after bunch emergence. Conventional fertilizers are mainly nitrogen, phosphorus and potassium, but the application rate of nitrogen fertilizer should be reduced, especially nitrate nitrogen, to avoid excessive vegetative growth of the plant causing delayed bunch emergence, or flower drop after bunch emergence. In addition, bananas are high-potassium plants. During the bunch emergence stage, flower bud differentiation should be promoted, so boron and zinc elements should be supplemented to promote root growth and development and improve the root system's absorption capacity, while calcium and phosphorus should be maintained to promote young fruit growth.
2. Bunch alignment and bunch cutting
Bunch alignment refers to moving the flower bud growing on the leaf stalk away from the leaf stalk to reduce its resistance, so that the flower bud can hang down and grow, which is beneficial to flower bud development. Before bunch cutting, flower removal is needed. When the flower bud turns black, the flowers on the fruit hands should be removed to prevent the sap flowing out after the flowers fade from dripping onto the fruit and affecting the fruit's appearance and variety. After flower removal is completed, bunch cutting can be done. When there are 2 to 3 hands of flowers that do not set fruit after fruiting, cut off the tail ends of their flower buds. Together with short bunch cutting, fruit thinning is also carried out. Generally, the fruit at the tail end 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 bunch emergence period, a large amount of nutrients is consumed, and the plant's resistance decreases. At this time, there is sometimes a high-temperature and high-humidity environment, which is extremely likely to cause pests and diseases, so pesticides should be sprayed promptly before and after bunch emergence to prevent pests and diseases. In order to improve the plant's disease resistance, when spraying pesticides, micro-nutrient resistance can be added to improve the plant's own immunity and improve disease resistance.
4. Waterlogging prevention
Bananas have fleshy root systems. During the bunch emergence period, their water requirements are relatively strict. The soil must be kept moist so that there is sufficient water for growth, but they are also afraid of excessively wet soil or standing water, which can cause root rot. During bunch emergence, it is precisely the period with more rainfall, so drainage measures should be taken well to avoid standing water soaking and rotting the roots and affecting growth and development. After rain, ditch digging and drainage measures can be adopted, and organic fertilizer can also be applied to supplement the soil's organic matter, improve soil structure, and promote root growth.
