1, rootstock selection
After several generations of selection, "Green Orange" with stable characters was selected as the most suitable variety. The suitable rootstock for green orange is red orange from Jiangxi or Sichuan, or lime from Guangdong.
Step 2 plant
The plant spacing is 3m× 4 ~ 5m, the close planting is 2.5m×4.0m, and the number of fixed plants is 660 ~ 825 plants /hm. What is the length of the planting hole? 80cm, 80cm wide and 80cm deep. Before planting, 20 ~ 30 kilograms of decomposed organic fertilizer and core soil are mixed and filled at the bottom of the hole, and the top soil is used to fill the 20 cm high mound. After the soil layer settles, plant it, transplant it with soil, and water the roots after planting. The planting depth is the same as the nursery.
3. Water and soil management

Mainly nitrogen fertilizer, combined with phosphorus and potassium fertilizer, a small amount of multiple applications. Fertilize the shoots 6 ~ 8 times in spring, summer and autumn, and topdressing them in bud stage and mature stage respectively.
5, plastic pruning
Molding trees according to local conditions can achieve the purposes of ventilation, light transmission, three-dimensional effect, labor saving and efficiency improvement. Adopt umbrella or tower tree. Light pruning is the main method in young trees. After selecting the extension branches of main branches and secondary branches, moderate to severe pruning is carried out, and the growth potential balance between main branches is adjusted according to the pruning degree and the direction of bud cutting. The remaining branches should be lightly cut to avoid excessive thinning and heavy cutting, and the dense branches should be appropriately deleted. Generally, the inner branches and weaker branches in the middle and lower part of the crown should be retained.
