Basin orange
(1) It is necessary to identify whether grafted seedlings grow faster than seedlings, have more fruits and will not change, so grafted seedlings should be selected. Observe the trunk of basin orange. There are hypertrophic grafting traces at 6 cm away from the soil surface, which is the healing tissue of scion and rootstock. Those without such traces are seedling. Different grafting methods also affect the growth and fruit setting of pot orange in the future. For the basin orange propagated by adjacent connection, the healing tissue formed at the adjacent connection is in a long strip, the healing line crosses the trunk obliquely, and the skin color on and below the healing line is the same. The healing tissue cut with a single bud was tumor like. The growth potential of single bud cut basin orange is stronger than that of adjacent basin orange, so the growth and fruit hanging in the future is better than that of adjacent basin orange.
(2) To buy small pots of oranges, the younger the pot of oranges, the stronger the vitality, the more conducive to re cultivation and fruit hanging. The age of the plant can be judged from the color of the trunk and primary and secondary branches. The age of branches grows from small to large, and the color of cortex changes from green → green → gray white to green → gray white to gray black → black brown.
(3) From the branches and leaves, choose the ones with symmetrical crown branches and solid branches. For example, some parts of the crown branches are crowded, some parts are empty, and the branches are low and messy. Don't buy them.
The leaves are green, especially from bottom to top and from outside to inside, indicating that the plant is strong. Although the leaf color is green, it has no luster. There are small gray and white spots on the leaves, or incomplete and curled, which are all the phenomena of insect damage. The withered leaves cannot be purchased.
The midvein of the leaf is yellow, indicating that the root system has been injured or rotten. If all the leaves are not green enough and the midvein of the leaves is yellow, the root system will rot a lot; If the midvein of the lower leaf is yellowing and the lateral vein is not yellowing, the root rot is not much.
(4) Select basin oranges from the situation of fruit hanging. If the fruit has been hung, select more, large and evenly distributed oranges. The fruit is bright red or orange yellow, but the color is not deep. If you pinch the fruit with your hand, it will feel swollen and solid. If the skin is not soft, wrinkled and the skin and flesh are not separated, the fruit viewing period will be longer. The leaves droop and the peel is soft and wrinkled. No matter what the color of the fruit, if it is not watered for a few days, there is a problem with the absorption function of the root. This kind of basin orange is of poor quality and is not easy to maintain.
