A summary of common lychee pruning mistakes, the latest key points explained in one article
Lychee is a fruit that many people like. It can only grow and bear fruit normally under good light conditions, but if the orchard is too dense and poorly ventilated, it will affect the light conditions, and at this time pruning is needed. But many people also fall into mistakes when pruning. Below, let's take a look at the common lychee pruning mistakes together.
1. Not paying attention to the degree of pruning
Many fruit growers prune haphazardly, and at the root they do not pay attention to the degree of pruning. The pruning degree for rotations in different regions and varieties is completely different, and lychee in different places cannot be pruned according to one standard. If pruning is too heavy after harvest, it will make it difficult for new shoots to sprout, the number will be too small, and it will be difficult to cultivate high-quality fruiting branches, affecting yield; but if pruning is too light, then the canopy cannot be effectively renewed and a high and stable yielding tree shape cannot be cultivated, which will also affect yield.
⟦NL>2. Not protecting the cut surfaces
After pruning, cuts and saw cuts of various sizes are left behind. If they are not treated in time or the treatment method is improper, the moisture in these cuts and saw cuts will quickly dissipate, causing drying and cracking, difficulty healing, and infection by pests and diseases. It will also affect sprouting branches, and may even cause dead branches and dead trees, increasing the difficulty and cost of cultivation management, and will also affect the tree vigor of the lychee tree and the yield of the coming year.
3. Uneven cut surfaces
When retracting fruiting branches, improper operation of pruning tools or directly breaking branches by hand will cause tearing of the cut surface, increase the density of wounds, and make healing more difficult. In addition, if the cut surface is uneven, moisture will dissipate faster, dry branches and dieback are very likely to occur, and it is also very susceptible to pests and diseases, seriously affecting the number and quality of new shoots sprouting near the cut surface.
4. Ignoring protection of the trunk
After heavy pruning, exposing the lychee trunk directly to sunlight can very easily cause sunburn and cracking of the bark, seriously affecting tree vigor. Moreover, branches that have dried and cracked will be harmed by pests and diseases, which not only affects the sprouting of new shoots, but is also unfavorable for trunk renewal. After heavy pruning, management needs to be strengthened. If the sun is too strong, a healing agent should be applied to the cut surfaces to promote healing, and fertilizer and water management should be strengthened at the same time to encourage the plant to sprout more new branches.
