What are the key technical points for post-harvest management of mango?
We are all familiar with mango, a tropical fruit that sells very well on the market. It is a fruit variety introduced to China from elsewhere. It contains relatively high levels of vitamins, carotene, protein, sugar and minerals, and its value on the market is growing ever higher. At present, the scale of mango cultivation in China has been continuously expanding. How should we manage mango after harvest? So let's read the content below together.
1. Pruning of branches and leaves
Generally, after mango harvest, pruning of branches and leaves is needed. 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, overgrown branches and leaves, diseased and pest-infested branches, excessively dense branches and leaves, and branches and leaves with low fruit yield. Secondly, we also need to reasonably prune the canopy of the mango tree to maintain a certain degree of permeability. 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 through pulling.
2. Orchard cleaning management
Cleaning the orchard is also a very important task, generally carried out after pruning of branches and leaves. At this time, we need to clean up the pruned branches and leaves as well as dead branches, fallen leaves, etc. It is best to remove these pruned branches and leaves from the orchard, and then burn them or bury them deeply. After the branches and leaves have been cleared away, we need to carry out comprehensive disinfection, sterilization and pest elimination in all parts of the orchard, especially in some dead corners, so as to effectively prevent and control pests and diseases and prepare for high yields the following year.
3. Later-stage topdressing
After mango harvest and orchard cleaning, we also need to apply topdressing, which can maintain the normal growth needs of the mango tree and promote its growth. 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 according to its growth condition. The later-stage topdressing of mango trees generally needs to be carried out in two applications. The first is before and after harvest, mainly using quick-acting nitrogen fertilizer, combined with phosphate and potassium fertilizer, ternary compound fertilizer, etc. The second is after entering winter, around November or December, mainly using organic fertilizer combined with nitrogen fertilizer. The amount of later-stage topdressing can be said to account for about 70 percent of the annual fertilization amount.
4. Drainage and irrigation
After mango harvest, if a dry season occurs and watering is not carried out in time, it will be very difficult for the mango tree to recover its vigor, which will have a great impact on the growth of the mango tree and its later fruiting. Therefore, we should water reasonably according to the water requirements of the mango tree. In addition, when there is a lot of rainfall, we need to drain excess water from the field to avoid greater losses, such as anthracnose, root rot and various other diseases.
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 tree trunks in November, which can not only play a role in cold protection, but also help prevent pests and diseases.
Mango is a fruit we greatly 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 you are interested, you can also carefully read the content above. I believe you can gain some unexpected benefits from it.
