Potted oranges, if not properly managed, will often only blossom, bear no fruit or little fruit, or even not blossom. In order to make potted oranges blossom and bear fruit every year, scientific management must be carried out in water, fertilizer and pruning to achieve fruitful results. Here, Uncle Gardener introduces several main links of potted orange management. 1. 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; The second is to adjust the rational distribution of nutrients in the tree by pruning, so that limited nutrients can be supplied to buds and leaves, forming more fruiting branches and making flowers and fruits full of branches. Before the spring shoots of potted oranges germinate, intensity pruning must be carried out. One is dead branches, diseased branches, clustered branches, inward branches, cross branches, sprouting branches and so on. Must be removed. Weakly cut strong branches, leaving 4 or 5 full buds; Prune the fragile branches vigorously, leaving 2 or 3 buds to promote each branch to produce more robust spring buds. After the spring shoots are full, in order to control the length, you can cut them lightly and cut off 3 or 4 branches. When the new buds grow to 6-8 knots in the future, in order to induce more summer buds, it is necessary to lose heart. Second, "lock water" before flowering: In order to prevent the summer shoots from growing luxuriantly, at the same time, trees should accumulate nutrients and promote the formation of flower buds, potted oranges should "lock water" before high temperature. Specifically, more than ten days before the arrival of hot summer, the water supply for potted oranges gradually decreased; Water was cut off five days ago, 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 dehydration of leaves, water can be sprayed on the leaves in the morning and evening, or a small amount of water can be sprayed on the soil in the basin, so that the axillary buds of oranges expand day by day and the color of the buds turns from green to white. When most axillary buds turn from green to white, "water withholding" will successfully promote flowers. At this time, the water supply of potted citrus should be restored in time. Third, protect the flowers and fruits: after the oranges bloom, in addition to applying thin fertilizer once a week, the flowers and fruits must be thinned. Thinning a part of flower buds before flowering; After the flowers wither and set fruit, some unsuitable young fruits are thinned out to reduce the consumption of nutrients, and the limited nutrients are concentrated on the reserved flowers and fruits, so that the fruits grow bigger and better. In the process of fruit growth, if there is enough fertilizer and water, the plants will have good nutrition, and some branches will sprout new buds, which will inevitably divert some nutrients and affect fruit growth. In order to preserve the fruit, the new buds should be pulled out in time. When the fruit is ripe, stop fertilizing, reduce watering and keep the soil moist and slightly dry. If you continue to give too much fertilizer and water, the fruit will ripen and fall off ahead of time, shortening the viewing time. Fourth, rational fertilization: oranges like fertilization, and thin fertilizer should be applied. Apply decomposed liquid fertilizer once before germination, and then apply liquid fertilizer with nitrogen as the main fertilizer every 7~ 10 days to promote the growth of branches and leaves and spring shoots. Fertilize in time after each coring to promote the early maturity of branches. In the growing period of oranges, you can sprinkle some cake fertilizer on the basin surface, so that some fertilizer will penetrate into the soil every time you water it, and enhance fertility. Reduce fertilization after autumn, avoid overnutrition of plants, promote autumn shoots, compete with fruits for nutrients, and lead to fruit drop. 5. Turn over the pot: Potted oranges have limited nutrient supply due to less pot soil. The soil fertility is insufficient year after year, and the citrus will weaken year by year, with few flowers and few fruits. In order for oranges to blossom and bear fruit every year, the jar must be turned over. The best time to turn over the pot is half a month before the oranges germinate. Before turning over the basin, prepare a basin bigger than the original one. Take the oranges out of the basin,
