Choose an orchard with suitable climatic conditions, deep and fertile soil, hard soil without water accumulation and close to water sources.
Second, the preparation of planting land
1. Planting density varies with climate, soil fertility and varieties. At present, the planting densities in various places are 5m× 4m (33 plants/mu), 5m× 3m (44 plants/mu) or 4m× 3m (55 plants/mu).
2. Preparation of planting holes: dig holes 2-3 months before planting, with a width of 80cm and a depth of 70cm. Apply 20-30 kg of decomposed pig manure, cow dung or soil miscellaneous fertilizer and 0.5- 1 kg of calcium superphosphate to each hole, and mix the fertilizer with topsoil and return to the hole.
Third, fertilization.
1, young trees are mainly fertilized with nitrogen and phosphorus, with appropriate combination of potassium fertilizers, phosphorus fertilizers such as calcium superphosphate and bone meal are mainly used as base fertilizers, and nitrogen fertilizers are mainly topdressing.
After field planting, topdressing will be started when seedlings are pulled out 1-2 times, and topdressing will be done once in March, May, July and September, and urea 10-20g will be applied to each plant, and compound fertilizer will be applied in September.
2. Fertilization of fruit trees is mainly based on nitrogen and potassium fertilizers, and the amount of potassium is not less than nitrogen, and phosphorus, calcium and magnesium fertilizers are added.
Fourth, plastic trimming.
After the young trees were trimmed and planted, the height of the seedlings was 80- 100 cm, and the shaping began. When the height of natural round-headed crown is 80- 100 cm, the stem seedlings are picked or cut short to promote trunk branching. At this time, the pruning of the fruit tree is mainly short cutting and thinning.

Growing habits:
Growth habit of bud tip Mango buds grow in a crown-like way, and the buds are wrapped by bracts. When growing, the bracts bloom first, the buds are elongated, the leaves are unfolded, and the bracts fall off immediately.
The middle and lower leaves alternate, and the leaf spacing is large. Generally, branches are taken 6-8 times a year at seedling stage and young trees, 2-4 times for young fruit trees and 1-2 times for adult trees.
Bamboo shoots are spring bamboo shoots in March-May, summer bamboo shoots in June-August, autumn bamboo shoots in September 9- 10/October165438+1October and winter bamboo shoots in June-February. Autumn shoots are the main fruiting branches in Hainan.
However, spring shoots and summer shoots can also become fruiting mother branches. Under better conditions, some varieties of winter shoots can also blossom and bear fruit in 12-65438+ 10. It takes 15-35 days from bud germination to bud stop growth and leaf maturity.
Summer and autumn shoots last for a short time, while winter shoots last for a long time. Branch growth and root growth alternate.
