How to prune orange trees

(1) Small happy pruning of overlapping branches and leaves and canopy shading will seriously affect the photosynthesis of leaves in the inner chamber.

(2) Cut off the top branches of the compressed lower branch group by 1/2- 1/3, so that the upper branch group becomes light and inclined, and the lower branch group continues to droop without pruning, naturally forming an open and transparent state.

(3) Delete overlapping dense branches to achieve the purpose of seeing light in the hole.

(4) According to the specific situation, delete or truncate the fruiting branches, fruiting mother branches and weak branch groups of the previous year.

After the shoot is fixed, the navel orange should master the following points when setting the spring shoot after flowering and fruiting:

① Pruning method: Pruning in spring and summer mainly deals with new small branches.

(2) Pruning goal: to prevent the lower branches and leaves from being ventilated and transparent due to too many new branches and crowded new branches.

③ Pruning degree and pruning amount: Different from summer pruning, each tip is not cut short in spring, and the pruning degree and pruning amount are much lighter. Just cut off some overlapping branches and cross branches to make the branches and leaves ventilated and transparent.

Extended data:

First, the introduction of orange tree:

Citrus reticulata is a small evergreen tree of Rutaceae, which is native to China and widely distributed in the provinces south of the Yangtze River. It is about 3 meters high. Branchlets are thinner, glabrous and usually spiny. It blooms in spring and matures in February 10 ~ 10.

Orange trees are evergreen all year round, with dense branches and leaves, neat tree posture, blooming flowers in spring, and heavy yellow and yellow-green fruits in autumn and winter are extremely beautiful.

Second, the cultivation techniques:

It is required that the soil layer is deep (60㎝) and fertile; The ph value of the soil is 5.5-7.0; The slope of the orchard is less than 25 degrees. When planning a garden, there should be necessary roads, irrigation and drainage, water storage and ancillary building facilities. In terms of specific planning, we should concentrate on one place as much as possible and build gardens in places with good traffic and water conditions.

1) Digging planting holes with soil: pull wires at a fixed distance, dig planting holes with a depth of 80cm and a width of 80 cm, then press green manure 50cm deep and backfill soil 40cm high for planting;

2) Ridge planting: 8m, 60-80㎝ wide and 40-60cm deep, with every 2 ridges (width 1.5m, center distance 4m, height 20-30cm).

3) When planting, trim the roots of the seedlings moderately, place them in the center of the planting hole, stretch and straighten the roots, and gently lift the seedlings upward while filling the soil, so that the roots are closely connected with the soil. Water the roots, make a 1m tree tray around the seedlings, and cover it with chaff.
