Latest Key Technical Points for Post-Harvest Management of Pomelo Trees

After the pomelo harvest is complete, it is time to prepare for next year's bumper crop, so post-harvest management is very important. The main aspects of late-stage pomelo tree management that need attention are topdressing and orchard management. To help them get through a nutritious and healthy winter, growers still need to put in a great deal of effort. Below, the editor will give you a detailed introduction to several key points.

1. Topdressing

The pomelo tree has just finished its fruiting period, and its nutrient consumption is very high. Generally, no topdressing is applied in the month before pomelo harvest, so at this time the pomelo tree urgently needs nutrient supplementation. Sufficient nutrients can help it better resist the low temperatures of winter and keep it vigorous. So what kind of fertilizer should be applied? The editor suggests that growers bury farmyard manure around the roots. This type of fertilizer contains a complete range of trace elements and is most suitable for supplementing the nutrients the pomelo tree needs at this time. At a distance of 20 cm from the main trunk, form a circle with the manure around it, then cover it with soil.

2. Orchard Cleanup

Many pest and disease sources of the pomelo tree attach themselves to the branches and leaves, waiting for the chance to revive again next year, and some of the residual branches and leaves left during harvest carry these sources with an extremely high probability, so cleaning up the residual branches in the orchard is very important. If these residual branches are not cleaned up thoroughly, the pest and disease sources will slowly absorb nutrients as the residues rot, and finally enter the soil along with them, allowing them to evade the low-temperature season and planting hidden dangers for later disease outbreaks. Farmers should pay attention to this aspect.

3. Branch and Trunk Pruning

Fruit trees are not better the denser they are; excessive density reduces the fruiting rate and competes for nutrients. After harvest is finished, clearing some branches and trunks becomes very necessary. When pruning, note that areas that are dense but bear little fruit should be focused on for clearing, so as not to reduce yield. The branches and leaves above fruiting points must not be allowed to become too dense, which would make it difficult for the fruit to enjoy sunlight and reduce quality. Those growing in scattered directions and not concentrated upward need to be cleared away, as they affect the growth of the fruit tree. These are the three points to note.

4. Insulation Measures

After the pomelo harvest, the arrival of cold winter basically follows, so insulation is extremely necessary; otherwise, if the fruit trees are frostbitten or frozen to death, unnecessary losses will be caused. For root insulation, mounding soil can be used, that is, piling the soil around the roots higher to achieve an insulation effect. If the temperature is below zero, or if freezing disasters occur, insulation film can be added for the pomelo trees so they can get through winter safely.

Post-harvest management of pomelo trees is very important, as this is the first guarantee of next year's high yield. A good harvest in the current year only means we did well before; we must also pay attention to the harvests that follow.
