The pruning method of orange tree

Orange is a common fruit, many people like to eat oranges, so many fruit growers have planted orange trees, pruning orange trees is a very headache, let's take a look at the pruning methods of orange trees.

I. pruning requirements for each growth period

1. Vegetative growth period: on the basis of fixed trunk shaping of seedlings, the crown was mainly cultivated by shaping, and the main branches and auxiliary main branches were selected in the first and second year after planting, and the lateral branches were arranged to make the tree compact and luxuriant branches. The shoots were cultivated 3 or 4 times a year to form a crown as soon as possible and remove the buds in time.

two。 Growth and fruiting period: continue to cultivate the crown and bear fruit in an appropriate amount. Promote the development of new shoots 2-3 times a year, the shoots are dense and evenly arranged, and form a compact crown as soon as possible. The middle and upper part of the plant did not bear fruit or had little fruit during the day, and the pruning was mainly to wipe buds and control shoots.

3. Full fruit period: the height of the tree is generally controlled below 250cm, the crown opens, the periphery is concave and convex, the branch growth is robust, the thickness of green leaf layer should be above 100cm, ventilated and transparent, three-dimensional fruit. Control the crossing between rows, and the crown coverage is 75%-85%. Pruning according to the tree system, cut the density to stay sparse, remove the weak and stay strong; cut it and leave it inside; cut more trees with more flowers, and cut trees with fewer flowers lightly.

4. Aging period: retraction pruning, renewal or thinning of old fruiting branches, forcing new fruiting branches in the inner chamber or lower part, keeping sprouting, densification and thinning, arrangement, more flowers and more pruning, and appropriate strong pruning of weak trees.

II. Pruning period

From early February to mid-March in spring and from early July to mid-August in summer and autumn. In addition, auxiliary pruning such as wiping buds and controlling shoots and pruning flower branches were carried out from late April to early July.

Third, pruning methods

It can be controlled flexibly according to the characteristics of each variety and the strength of the tree.

1. Trees with many flowers should be re-pruned, thinning and cutting should be combined with truncation, while trees with few flowers should be cut lightly, only some dense branches and thin and weak branches should be deleted.

two。 Withered branches, serious disease and insect branches, all cut off from the base.

3. The senescent branch group should be renewed or thinly deleted, and the length of the regeneration branch depends on the strength and position of the branch group.

4. Cross branches and long branches are cut off from the base in principle, but when the middle and lower parts of the crown are empty, they can be appropriately cut short as new branches or fill the gap; dense branches should be thinned and excised if they are too long.

In fact, the pruning of orange trees is relatively simple, in addition to pruning, but also pay attention to the management of water and fertilizer.
