2. When the seedlings of potted kumquat grow to 20 cm or white, they need pruning, and the redundant parts should be cut off in time, or the buds at the top of the seedlings should be wiped off by 3 ~ 5 cm, which can effectively resist the white growth of seedlings and promote the sprouting of new branches of potted kumquat.
3. Potted kumquat seedlings are dry and need to be pruned properly. Generally, the long part of the trunk is cut off, and all other branches are cut off, only 4 ~ 5 branches can be kept. At the same time, all the buds at the top should be cut off so that potted kumquat can grow better.
4. Kumquat can be pruned 7- 10 days before spring shoot germination, and the branches with diseases and pests, old branches, overlapping branches, clustered branches and cross branches can be cut off. Can be combined with the shape of potted plants, according to the shape of the round head, pagoda pruning.
Potted kumquat must be pruned as soon as possible. If the shoots have been removed and the branches are too long, attention should be paid to protecting the compound buds at the base of the plant so as not to affect the germination. Loosen potted kumquat, sparse dense branches and long branches, cut off dead branches and diseased branches, and make the crown branches distribute reasonably and evenly.
6. After March every year, most of the fruits of potted kumquat naturally fall off. In order to save nutrients, the remaining fruits should be picked manually, and at the same time, branches that are too dense, cross branches, some branches that are too prosperous, and branches with no bare cavities should be thinned. The reserved annual branches should be cut short, and the mouth buds should be cut off, and 2 ~ 3 outer buds should be left on each branch.
7. After daily pruning, potted kumquat can greatly reduce the consumption of soil nutrients, concentrate the nutrients in the soil and promote the growth of potted kumquat. For potted kumquat with skewed tree shape and improper orientation of main branches, the orientation can be adjusted by hanging stones and pulling ropes, so that the main branches are evenly distributed and the crown is round. After each pruning, carbendazim can also be sprayed appropriately to prevent bacteria from infecting the wound.
8. In order to reduce the nutrient consumption of potted kumquat, so that the nutrients can reach the strong branches more intensively and fully, and also to improve the permeability of the plant and maintain a good modeling effect, potted kumquat must be pruned in autumn, mainly by cutting off the slender branches and endogenous branches that grow too thin on the plant.
9. During the flower and fruit period of potted kumquat, we should pay attention to thinning flowers and fruits, keep the first flowers, and remove the late flowers and weak flowers. Generally, the flowering and fruit setting rate is high from May to June, and more flowers and fruits should be left after July.
10, when potted kumquat is young, the fruit must be combed. According to the growth and fruit of the plant, 3-5 fruits can be left in each branch, and all the excess fruits should be removed. It not only makes the retained fruits grow stronger and brighter, but also prevents the phenomenon of small fruits caused by insufficient nutrients, and also ensures that the plants also have enough nutrients to continue to grow.
