The planting time of this kind of citrus is the same as that of ordinary citrus. Before planting, the land should be sorted out in advance. In general, it is enough to make holes. There is also the need to dig a planting hole, the width and depth of the hole should be about 80-90 cm, then sprinkle 40-50 cm of base fertilizer into the planting hole, and then cover it with fine soil. Then put the citrus seedlings in the hole. When planting, fully stretch the roots of citrus, then straighten the seedlings and fill them with soil. After planting, add some water to the citrus seedlings.
3. Water and fertilizer management. This management is very important and will directly affect the yield and quality of ugly oranges. Therefore, when applying fertilizer, we should fully understand what nutrients are needed in its growth process, and then replenish them in time. The main fertilizer is organic fertilizer, and then some fertilizers are used reasonably. Fertilization methods can be ring application, furrow application, hole application, etc. , combined with foliar fertilizer. Young ugly orange trees should be topdressing at least 5-6 times a year, during which nitrogen fertilizer is the main factor. Adult ugly orange trees should be topdressed 3-4 times a year, and appropriate fertilizers should be selected according to different growth cycles.
4. Prune citrus trees. Proper pruning of ugly citrus is also a way to increase production. In the process of pruning, we should ensure the permeability and three-dimensional sense of the orchard. When it is still young, in order to adjust the growth balance between branches, it is necessary to give priority to light pruning. If it is a citrus tree that has just begun to bear fruit, it is necessary to prune the main branches in various places to help the side branches grow. When the citrus tree is flourishing, it is necessary to prune useless old branches, diseased branches and weak branches.
