Put the seedlings in the middle of the flowerpot and spread the roots around. If the trunk root or lateral root is too long, a section can be cut off as appropriate to promote the generation of new roots. Fill fine soil with mud powder near the roots of seedlings, and then fill nutrient soil. Raise the seedlings several times to make the fine soil in close contact with the root system. Put it indoors, pay attention to watering it in time, avoid dry soil and keep a certain humidity. When the new buds are moved out after germination, it is best to put them under the shade shed. After about a month, the shade shed can be folded for all-day irradiation. Water management Citrus is fertilizer-tolerant and water-loving. However, the management of water and fertilizer in the flowering and fruiting period is quite special, which is called dry flower and wet fruit. The so-called dryness means watering the topsoil when it is dry and white, so as to keep the basin soil in a semi-humid state. Too much or not enough water will cause plants to drop flowers. The so-called wet refers to the timely and thorough water supply in the process of fruit production.
The soil in the pot should be kept moist, otherwise it will cause the plants to drop fruit. During the winter dormancy period, water should be given according to the dry and wet conditions of the basin soil. Fertilization It is very important to fertilize potted citrus. The principle of fertilization is to apply it frequently and thinly, and then apply it at the critical period. Rhizosphere fertilization began before and after germination in spring. Branches, leaves and young fruits of citrus can not only be absorbed by roots, but also absorb fertilizers to varying degrees. When changing pots, dump the plants in the original pot, cut off the densely aged reticular root mat on the outer layer of the root with branches, remove the soil around and at the bottom of the root, then put it into the original pot or a new pot, add new nutrient soil, spray water once, and trim the aboveground parts moderately at the same time. After that, routine management is carried out. Note: potted citrus is characterized by short trees, dense crowns, dense branches and many fruits, and its ornamental value is enhanced.
Therefore, special attention should be paid to the cultivation of tree skeleton structure when modeling and pruning, so as to shape a compact tree. Generally, orange seedlings with three main branches are transplanted into pots. If it is an annual seedling, it should be cut short in the year after transplanting to promote the germination of new buds in the middle and lower part of the trunk, and then three new buds with suitable distribution parts should be selected as the main branches for culture. Spring buds extracted from other parts should be thinned or cored as appropriate; Wipe off the summer tips at any time so as not to disturb the trees. In order to reduce the nutrient consumption of potted citrus trees and improve the fruit setting rate, autumn shoots were used as the main fruiting mother branches of potted citrus trees. Since May, use flower buds twice a week. For clustered or * * * existing buds, one bud should be selected in the correct position, and the rest should be erased. At the same time, the horizontal branches or buds should be smoothed, and the buds with five leaves and no flowers should also be smoothed to promote the branches to be full and strong.
