Key Management Techniques for Pomelo Trees After Harvest

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 areas that need attention in the later management of pomelo trees are topdressing and orchard management. To help them get through a nutritionally healthy winter, growers still need to put in a great deal of effort. Below, the editor will give you a detailed introduction to a few 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 replenishment. Sufficient nutrients can help it better resist the low temperatures of winter and keep it vigorous. So what should be applied as fertilizer? 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 replenishing the nutrients the pomelo tree needs at this time. At a distance of 20 cm from the main trunk, form a circle around it with the manure, then cover it with soil.

2. Orchard Cleanup

Many sources of pests and diseases of pomelo trees attach to the branches and leaves, waiting for the chance to revive again the following year. Some of the residual branches and leaves left at harvest carry these sources with an extremely high probability, so cleaning up the orchard's residual branches is very important. If these residual branches are not cleaned up thoroughly, the pest and disease sources will slowly absorb nutrients as the residue decomposes, and finally enter the soil with it, allowing them to survive 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, so cleaning up some branches and trunks after harvest becomes very necessary. When pruning, note that areas that are dense but bear little fruit should be the focus of cleanup, to avoid reducing yield. The branches and leaves above the fruiting points must not be allowed to become too dense, otherwise the fruit will find it hard to enjoy sunlight and quality will be reduced. Those whose growth direction spreads in all directions and does not grow concentrated upward need to be cleaned up, as they will affect the growth of the fruit tree. These are the three points to note.

4. Insulation Measures

After the pomelo harvest, the cold winter basically arrives along with it, so insulation is extremely necessary; otherwise, if the fruit trees are frostbitten or frozen to death, unnecessary losses will be caused. Root insulation can be done by mounding soil, that is, piling the soil around the roots higher to achieve the insulation effect. If the temperature is below freezing, or if frost damage occurs, insulation film can be added for the pomelo tree so that it can get through the winter safely.

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