Preventive measures of banana fruit cracking

In the late stage of banana fruit development, the pericarp is prone to vertical phenomenon, and the crack will rot after rain, while in the dry climate, the pericarp near the crack will dry up. Moreover, it will also induce diseases and insect pests, seriously affect the fruit yield and quality, and cause huge economic losses, so how to prevent banana fruit cracking? Let's take a look at the detailed introduction.

1. Strengthen the management of fertilizer and water

The main reason for banana fruit cracking is due to climate change, such as sudden rain in a long drought, the pulp will become thicker rapidly because it absorbs too much water, and the peel can not keep up with the growth rate of the pulp. Therefore, the management of banana should be strengthened in the later stage of banana growth. after the budding of banana, farm manure or organic fertilizer can be applied to improve soil structure, make soil loose and fertile, promote root growth, enhance tree potential and improve disease resistance. During fruit development, water should be watered every 3-5 days in case of drought to keep the soil moist and pay attention to the application of phosphorus and potassium fertilizer to ensure adequate nutrients.

2. Extra-root fertilization

After the banana bud is broken, the demand for nutrients is higher, and the root absorption of some plants can not catch up with the needs of its growth, so it is necessary to promote its growth by foliar spraying. Generally, foliar fertilizer is sprayed every 7-10 days. Banana Dabao 800-fold liquid or poly-nucleotide-free 200-fold liquid or 1000-fold solution of high-efficiency leaf potassium green abundant element can be used to promote fruit development.

3. Bagging

In the period of fruit development, it should be checked frequently. If the phenomenon of fruit cracking is found, the banana strips with split fruit should be cut off in time and concentrated treatment to prevent the occurrence of fruit cracking. In order to reduce the occurrence of fruit cracking, when the young fruit of the banana is combed upward, the special bag of the banana can be used to cover the banana ear, which is beneficial to the fruit development and has a better effect on preventing fruit cracking.

4. Timely harvest

Bananas will also crack when they are overripe, so when they are ripe, fruits that are sold far away are generally harvested when they are ripe, while those sold locally can be harvested when they are ripe. In order to avoid banana overripe fruit cracking phenomenon is more serious, reduce the loss.
