Flowers are common, so are trees. But have you ever planted fruit trees on the balcony? Planting a fruit tree on the balcony can not only enjoy the beautiful scenery of greening, but also enjoy the wonderful experience of picking flowers, and this good thing of killing three birds with one arrow naturally makes all kinds of flower gods set off one after another. But growing fruit on the balcony is not just a heartbeat. Action is also the key. Some time ago, a flower friend asked uncle gardener for help. "Hello, uncle gardener, I'm from Yantai. My lemon bore fruit last year, but it has no leaves this year. What happened? What should I do? " In fact, these problems are all caused by Huayou's failure to do maintenance work before and after lemon fruit last year. This lemon fruit actually needs a lot of nutrition like pregnancy. Need to "before giving birth", there will be a moon meal after giving birth, so that the lemon will be restored in the coming year, and the lemon will be full of flowers and fruits! However, if the topdressing work is not done in time, the situation mentioned by this flower friend will easily occur in the coming year, and the lemon will not grow leaves. Just like a lemon tree that specializes in eating fruit, the crown of the young tree can reach more than 80cm in two years in order to bear fruit earlier. Every autumn, fruit farmers will control the use of nitrogen fertilizer, increase the application of phosphorus fertilizer and potassium fertilizer, and promote the continuous differentiation of flower buds. In the summer and autumn of the second year of lemon seedling planting, the first, second and third main branches at the bottom were removed and the position was adjusted, which weakened the growth of chess nutrition, thus promoting the differentiation of flower buds and making its nutrition contribute more to the fruit. In the year before the planned production, all summer shoots will be erased one after another, and autumn shoots will be planted in early September to cultivate strong female branches and promote flowering and fruiting. For those small trees that grow too strong, rooting in autumn is a good way to promote flower bud differentiation. For trees that need fruit, these practices can make fruit trees in a better state in the coming year. At this time, we must do the three keys mentioned above. The first key, rational use of fertilizer: lemon fertilization is basically the same as other citrus bridges, but potassium fertilizer needs more. The focus of fertilization is to re-apply autumn fertilizer and winter fertilizer, such as fertilization before flowering and fruit stabilization. Fertilize 4~5 times a year, mainly with organic fertilizer and biological special fertilizer, and cooperate with quick-acting fertilizer and medium-trace element fertilizer to meet its growth. For example, in spring, flower lovers need to spray 300 times of sea elf biostimulant on weak trees and trees with excessive flowering, so that nitrogen fertilizer, phosphorus fertilizer and boron fertilizer can be added before and after flowering, combined with pest control and spraying. Can play an effective healing effect. In summer, lemon trees should be supplemented with liquid fertilizer and sprayed with 800 times of sea elf biostimulant for 2~3 times. Stimulate its growth. Before putting bamboo shoots in autumn, heavy fertilizer should be applied to lemon trees to balance the trace elements in organic fertilizer or high potassium compound fertilizer. Weak trees with more fruits in the upward direction can be watered once with sea elves to help restore the tree's vigor. In winter, organic fertilizer and phosphorus and potassium fertilizer should be applied again to reduce deciduous leaves in winter and ensure the quantity and quality of lemon flower bud differentiation. The second key, plastic pruning: Lemons are pruned many times a year, so besides winter pruning, more pruning is aimed at summer pruning. For example, the strong trees should be lightly pruned in winter, and the strong branches and dense branches at the top of the crown should be smoothed or shortened in summer. Weak trees are cut again in winter and slightly in summer to promote rejuvenation. For those trees that bear fruit at the beginning, cut them lightly, delete the weak branches appropriately, and cut off the rotten parts at the top of the bearing branches. However, after the lemon tree enters high yield, it will leave 8~ 10 leaves for the longer spring shoots and autumn shoots to pick the core. Erase all summer buds and promote the release of autumn buds. And timely erase the spring and autumn buds with dense buds and poor position. this

Because the base of lemon filament is continuous, the filament is not easy to fall off after the flower withers, so in rainy days, lemon filament will tightly wrap the young fruit, and some petals will stick to the small fruit, so that the young fruit will turn yellow and fall off without sunlight. At the same time, it will also lead to the occurrence of leaf moths. Therefore, shaking trees and petals every 3~4 days after flowering, combined with spraying drugs to control pests, can improve the fruit setting rate. Lemons need to consume a lot of nutrients when they bloom and set fruit. Therefore, flower lovers should remove too many, too dense or too weak buds to reduce nutrient consumption and improve fruit setting rate. Spraying gibberellin biological stimulator for the first time after flowering and before the first physiological fruit drop, and spraying gibberellin biological stimulator for the second physiological fruit drop is helpful to stabilize the fruit. If there are too many spring flowers in the lemon tree, the plants with too many fruits can thin the fruits in time from late June to early July after the second physiological fruit drop to ensure the fruit quality. It is advisable to leave 30~35 leaves per fruit. Thanks for reading. Friends who like it can like it or share it. If you want to know more, you can pay attention to Uncle Gardener ~
