The requirements of potted orange trees for tree selection, spray shaping and branch pulling;

1, tree shape Select the tree shape of potted fruit trees. According to the different requirements of fruit tree types and varieties, such as vertical and drooping, imaginative trees can be shaped, such as natural round head, tower, one cliff, two antlers, three cups, weeping willows and dragon curves. Make it not only beneficial to the result, but also have aesthetic effect and improve its ornamental value.

2. Chemical control technology is applied to spray shaping to dwarf trees. In summer, during the vigorous growth period of potted fruit trees, plant growth retardants (such as chlormequat chloride and paclobutrazol) should be sprayed on the leaves for 2-3 times, which can make branches stout, internodes shorter and plants shorter. In addition, the measures to promote the dwarfing and pruning of flowers mainly include: wiping buds, removing cores, taking branches, bending branches, ring cutting, retracting and renewing.

3. Pull branches, etc. Through the angles of open branches and sparse branches, dense branches and invalid branches, the illumination is enhanced and the ideal tree shape is obtained.

4. Flower and fruit management When the number of flower buds of fruit trees is large, flowers should be thinned during the pregnancy of flower buds, and fruits should be thinned after the physiological fruit drop period; If there are few buds, you can leave more flowers and pollinate artificially at the same time.

In the case of meeting the above conditions, let's introduce the potted methods of orange trees:

First, select a container.

The container of potted fruit trees is mainly round, which is beneficial to the uniform stretching of the surrounding roots. At the same time, the container needs water seepage and good air permeability to ensure the oxygen demand for root growth and prevent root rot due to water accumulation in the container.

Among all kinds of containers, the plain pot is the most suitable for planting fruit trees. When using containers made of other materials, in order to overcome the shortcomings of poor air permeability, coarse sand with a thickness of 5 cm can be laid at the bottom of the basin, and a new layer of tiles can be placed along the inner wall, and then trees can be planted by filling the soil.
