1. The main links of management are as follows: reasonable pruning; There are two reasons for pruning potted oranges. First, the pot is small, the soil is small, and the nutrients provided are limited, which cannot meet the needs of orange growth and must be pruned. Second, through shaping and pruning, the rational distribution of nutrients in trees can be adjusted, so that limited nutrients can be supplied to buds and leaves to form more fruiting branches, thus achieving full flowering and fruiting branches.

2. Before the spring shoots of potted oranges germinate, the intensity pruning must be carried out. First, dead branches, diseased branches, overgrown branches, inward branches, cross branches and sprouting branches should be removed. Cut the strong branches weakly, leaving 4 or 5 full buds; The weak branches are strongly cut, leaving 2 or 3 buds, so that each branch can produce more robust spring shoots. After the spring shoots are fully grown, in order to control their vain growth, they can be lightly cut and cut off 3 or 4 branches. When the new shoots grow in the future have 6 ~ 8 knots, they will be cored, in order to induce more summer shoots.

3. "Water withholding" before flowering In order to prevent the summer shoots from growing excessively, and at the same time, the trees should accumulate nutrients and promote the formation of flower buds, the potted oranges should be "water withheld" before the summer. The specific method is that the water supply to potted oranges is gradually reduced more than ten days before the summer heat; The water supply was stopped in the first 5 days, and the basin soil was exposed to the sun, and a large amount of water evaporated and the basin soil was dried; Because of the lack of water in the root system, the branches and leaves lose water, and the leaves are shriveled and curled. In order to prevent the leaves from dehydration, water can be sprayed on the leaves in the morning and evening, and at the same time, a small amount of water can be sprayed on the basin soil, so that the axillary buds of oranges are expanding day by day under the condition of drought and not dying, and the color of buds turns from green to white. When most axillary buds turn from green to white, "withholding water" will be successful in promoting flowers. At this time, it is necessary to restore the water supply to potted oranges in time.

4. flower and fruit protection: after the orange blooms, in addition to applying thin fertilizer once a week, it is also necessary to sparse flowers and fruits. Sparse some buds before the flowers bloom; After the flowers wither and the fruits are set, some young fruits in improper positions are thinned, so as to reduce the consumption of nutrients, let the limited nutrients concentrate on the preserved flowers and fruits, and make the fruits grow bigger and better. During the fruit growth, if the fertilizer and water are sufficient and the plant nutrition is good, some branches will sprout new shoots, and the growth of new shoots will inevitably divert some nutrients and affect the growth of fruits. In order to keep the fruit, the new shoots should be erased in time. When the fruit is yellow, stop fertilizing and reduce watering to keep the soil moist and slightly dry. If we continue to give too much fertilizer and water, the fruit will ripen and fall early, shortening the viewing time.
