At the seedling stage, when the seedlings grow to about 1 m, the branches that grow too messy, dry and yellow should be pruned; In the fruit-bearing period, branches that cannot bear fruit, twigs and branches infected with diseases need to be pruned in the fruit-bearing period; In the aging period, after entering the aging period, the diseased branches and dead branches should be pruned; Trimming and shaping. After pruning, it should be trimmed and reshaped according to the overall growth situation.

1, seedling stage

When the seedlings of orange trees grow to about 1 m after sowing and germination, they need to be pruned properly, the leaves and branches that grow too disorderly need to be pruned, and the dry and yellow branches need to be pruned so that the plants can grow more vigorously in the later stage.

2. Fruiting period

In the fruit-bearing period of citrus trees, it is necessary to prune overgrown branches, bald branches, weak branches and infected branches, so that plants can grow new branches, thus improving the yield and quality of fruits.

3. Curing period

After the orange tree enters the aging period, it is necessary to prune the diseased branches and dead branches to reduce unnecessary nutrient consumption. Plant ash should be sprayed on the wound after pruning to avoid exposure of tissue fluid. It is also necessary to spray carbendazim solution on the whole plant once to make the wound heal as soon as possible.

4. Dressing and shaping

After pruning, citrus reticulata should be pruned and reshaped according to the overall growth situation, so as to make the plant shape more beautiful. Branches and leaves that grow too densely can be thinned, and branches that grow too long can be cut short to reduce unnecessary nutrient consumption and concentrate on supplying nutrients to fruiting branches.
