The soil layer is required to be deep and fertile; the orchard terrain slope is less than 25 degrees. When planning the garden, there should be necessary roads, drainage and irrigation, water storage and ancillary building facilities. In the specific planning, try to concentrate as much as possible and build gardens in places with good transportation and water resources.

Citrus can grow in a wide range of soils, including purple soil, red and yellow soil, beaches and tidal flats, with a pH value of 4.5 to 8, with a pH value of 5.5 to 6.5 being the most suitable. Citrus root growth requires high oxygen content, loose soil texture, organic matter content of 2% to 3%, and well-drained soil.

The principle of fertilization should be to fully meet the needs of various nutrient elements in oranges. It is recommended to apply more organic fertilizers, rational application of inorganic fertilizers and formula fertilizers. Fertilization is guided based on leaf analysis results, orchard soil analysis results, orange phenological stages, etc.

Pruning

(1) Young trees: Mainly light pruning. After selecting the extended branches in the center of the cluster and the extended branches of each main branch and sub-main branch, cut them moderately or even severely, and adjust the growth balance between the main branches based on the degree of shortcut and the direction of the cut buds. In addition to appropriate thinning and deletion of overly dense branch groups, the inner branches and weak branch tips in the middle and lower parts of the crown should be retained.

(2) Early fruiting period: Continue to choose short cuts to extend the backbone branches at all levels to wipe out summer shoots and promote strong autumn shoots. In autumn, flower-promoting measures such as girdling, root cutting, and water control are adopted for vigorous trees.

(3) During the fruiting period: timely retract the fruiting branch group, the flowering and fruiting branch group and the declining branch group, and cut off light-blocking branches, dead branches, diseased and insect-infested branches.
