Magnolia grandiflora tree shape selection

Magnolia grandiflorum is magnificent, with a broad conical crown, mainly in the shape of natural stems

Pruning technology of Magnolia grandiflora

Breeding seedling trimming

After the grafted seedlings survive, the rootstock buds should be removed in time, the stem should be set up and pruned, and the trunk should be kept straight at the same time

Cultivation and shaping of large seedlings

Magnolia grandiflora will appear "double headed phenomenon" when it grows too fast. If the trunk grows too fast, the leaves near the top and the side branches should be removed in time. In order to avoid the phenomenon of top heavy and light, and the upper branches are easy to fall down after rain, the plants should be trimmed in time

The mixed buds at the tip of Magnolia grandiflora are usually one main bud and two auxiliary buds. The branches are relatively compact, and there are many inner bore branches and overlapping branches. It is necessary to delete and cut them in time. In the process of cultivation, we should pay attention to the selection of the reserved under branch height. According to the balance of seedling growth and overall growth, the lowest branch should be trimmed by 1-2 plates every year, and the appropriate under branch height is about 1-1.2m

Transplanting and out of nursery pruning

The method of thinning branches and picking leaves is often used, and it is best not to cut short. The pest branches, overlapping branches, inner bore branches and branches disturbing the tree shape shall be cut off in time, and the integrity of the tree shall be maintained. Generally, 1 / 3-1 / 2 of the leaves can be removed. Removing too many leaves will reduce the transpiration force and make it difficult for the roots to absorb water. In addition, the budding power of new branches of Magnolia grandiflora is weak, so it is best to bring mud balls when transplanting and leaving the nursery< span>
