What are the key technical points for post-harvest management of mangoes?

We are all familiar with mangoes; they are a very popular tropical fruit on the market. It is a fruit variety introduced into China from elsewhere, and it contains relatively high levels of vitamins, carotene, protein, sugar and minerals, giving it ever-greater value on the market. At present, the scale of mango cultivation in China has been continuously expanding. How should we manage mangoes after harvest? So let us read the content below together.

1. Branch and leaf pruning

Generally, after mangoes are harvested, branch and leaf pruning needs to be carried out. At this time, the mango tree's healing ability is still relatively strong, so the damage to the mango tree will be relatively small. When pruning, we mainly cut away cleanly some messy-growing branches and leaves, diseased and pest-infested branches, overly dense branches and leaves, and branches and leaves with few fruits. Secondly, we also need to reasonably prune the mango tree's canopy to maintain a certain degree of openness. Finally, we need to control the distance between the branches at all levels of the mango tree, and we can adjust the density between the branches at all levels by means of pulling.

2. Orchard clearing management

Clearing the orchard is also a very important task, and it is generally carried out after branch and leaf pruning. At this time, we need to clean up the pruned branches and leaves as well as dead branches, fallen leaves and so on. It is best to clear these pruned branches and leaves out of the orchard and then burn them or bury them deeply. After the branches and leaves have been cleared out, we need to carry out comprehensive disinfection, sterilization and pest elimination in all areas of the orchard, especially in some dead corners, so as to effectively prevent and control pests and diseases and prepare for a high yield the following year.

3. Later-stage topdressing

After the mangoes are harvested and the orchard is cleared, we also need to carry out topdressing, which can maintain the mango tree's normal growth needs and promote the growth of the mango tree. In addition, the mango tree itself is in poor condition after harvest, so in order to improve the nutritional level of the mango tree, we should scientifically apply maintenance fertilizer as a topdressing according to the mango tree's growth condition. The later-stage topdressing of mango trees generally needs to be carried out in two applications. The first is carried out before and after harvest, mainly based on quick-acting nitrogen fertilizer, used in combination with phosphate and potassium fertilizer, ternary compound fertilizer and so on. The second is after entering winter, around November or December, when it is mainly based on organic fertilizer, applied together with nitrogen fertilizer. The later-stage topdressing amount can be said to account for about 70 percent of the annual fertilization amount.

4. Drainage and irrigation

After mangoes are harvested, if a dry season is encountered and watering is not carried out in time, then the mango tree will find it difficult to recover its vigor, which will have a great impact on the growth of the mango tree and the later fruiting. So we need to water reasonably according to the mango tree's water requirements. In addition, when there is a lot of rainfall, we need to drain excess water out of the field, so as to avoid greater losses, such as various diseases like anthracnose and root rot.

5. Preventing freezing damage

The climatic conditions in many regions of China are actually not the most suitable for growing mango trees. If cold-protection measures are not taken well in winter, freezing damage is also very likely to occur. First, we can whitewash the trunk in November, which can not only play a role in cold protection but also help prevent pests and diseases.

Mango is a fruit we very much love, so it is also a fruit crop favored by many growers. Since it has been planted, it should be made to deliver greater economic value. So if everyone is interested, you can also carefully read the content above. I believe you can gain some unexpected rewards from it.
