If potted oranges are not properly managed, they often only bloom, but bear no fruit or little fruit, or even no flowers. In order to make potted oranges blossom and bear fruit every year, scientific management must be carried out in water, fertilizer and pruning, so as to achieve fruitful results. 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 can not meet the needs of citrus growth and must be pruned. Second, through pruning, the rational distribution of nutrients in the tree 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. The spring shoots of potted oranges must be pruned intensively before they germinate. First of all, we should remove dead branches, diseased branches, clustered branches, inward branches, cross branches and sprouting branches. Weakly cut strong branches, leaving 4 or 5 full buds; Strong pruning of weak branches leaves 2 or 3 buds, so that each branch can grow stronger spring shoots. After the spring shoots are fully grown, in order to control their imaginary length, they can be lightly cut and 3 or 4 branches can be cut off. When the new shoots grow to 6 ~ 8 knots, it is necessary to remove the heart to induce more summer shoots.

In order to prevent the summer shoots from growing too vigorously, at the same time, let the trees accumulate nutrients and promote the formation of buds, potted oranges should be "watered" before summer. The specific method is to gradually reduce the water supply to potted oranges more than ten days before the hot summer; In the first 5 days, the water was stopped, the basin soil was exposed to the sun, a lot of water evaporated, and the basin soil was dry; Due to the lack of water in roots, branches and leaves lose water, and leaves wither and curl. In order to prevent the leaves from dehydration, water can be sprayed on the leaves in the morning and evening, and a small amount of water can be sprayed on the pot soil at the same time, so that the axillary buds of oranges expand day by day under the condition of drought and not dying, and the color of the buds turns from green to white. When most axillary buds turn from green to white, "withholding water" will succeed in promoting flowers. At this time, it is necessary to restore the water supply of potted oranges in time.

Protect flowers and fruits:

After oranges bloom, in addition to applying thin fertilizer once a week, they should also be thinned. Sparse some buds before flowering; After the flowers wither and set fruit, some young fruits in inappropriate positions should be thinned out to reduce the consumption of nutrients, so that the limited nutrients can be concentrated on the preserved flowers and fruits, and the fruits can grow bigger and better. In the process of fruit growth, if the fertilizer and water are sufficient and the plants are nutritious, some branches will sprout new buds, and the growth of new buds will inevitably divert some nutrients, which will affect the growth of fruits. In order to protect the fruit, the new buds should be smoothed in time. When the fruit turns yellow, stop fertilizing, reduce watering and 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.

Rational fertilization:

Oranges like fat, so we should apply more thin fertilizer at ordinary times. Apply decomposed liquid fertilizer once before the plants germinate, and then apply liquid fertilizer mainly containing nitrogen every 7 ~ 10 days to promote more branches and leaves and more spring shoots. Fertilize in time after each coring to promote the early maturity of branches. During the growth of citrus, you can sprinkle some cake fertilizer on the basin surface, so that some fertilizer can penetrate into the soil every time you water it, and enhance the fertility. After autumn, fertilization will be reduced, plant nutrition will be avoided, autumn shoots will be promoted, and fruits will compete for nutrients, leading to fruit drop.

Turn the washbasin:

Because of the lack of pot soil, the nutrient supply of potted oranges is very limited After many years, the soil fertility is lacking, and citrus will weaken year by year, with few flowers and few fruits. In order to keep oranges blooming and bearing fruit every year, it is necessary to turn over the pots. The best time to turn over the pot is half a month before the oranges germinate. Before turning over the pot, prepare a pot one size larger than the original one, and take the oranges out of the pot without breaking the mud. Cut off the topsoil with a thickness of 1 and 2 cm along the mud lump, cut off dead roots and rotten roots, cut off the soil with a thickness of 1cm at the bottom of the mud lump, and take out the tiles embedded in the original pot bottom. The drainage holes of the new pool are laid with tiles. First, lay a drainage layer with a thickness of 2 or 3 cm, and then lay a layer of nutrient-rich culture soil with a thickness of 4 or 5 cm, which is mixed with a small amount of calcium superphosphate. Then put the orange paste into the pot, fill the cultivated soil around the mouth of the pot, slightly compact the pot soil, pour enough water, put it in a ventilated and semi-shady place, and put it back in place for daily management after one week.
