Soil ball size

The size of soil ball is the key to the success or failure of Magnolia grandiflora transplanting

Generally, the diameter of soil ball in East China is 8 to 10 times of the DBH of trees. The earth ball shall be excavated into gyro shape instead of plate shape and cone shape. The earth ball shall be tied tightly with straw rope to avoid loosening of the earth ball during transportation

Transplant season

Magnolia grandiflora should be transplanted in early spring, but it is best in plum rain season. When transplanting, it is best to choose cloudy or cloudy weather

It can be transplanted about half a month after the Spring Festival. When the temperature rises in late spring, the root system first sprouts and grows. In addition, the rainfall in plum rain season is large and the air humidity is high. At this time, the survival rate of transplanted magnolia is very high

Moisture requirements

The excavation, transportation and planting shall be carried out quickly and timely, so as not to affect the survival due to excessive water loss. After transplanting, the first root setting water should be timely, and should be fully and thoroughly watered. If there is too much precipitation after transplantation, a drainage tank shall be opened to avoid ponding at the root, resulting in the rotten root death of Magnolia grandiflora

if the weather is dry, spray or spray on the canopy. p>

Pruning requirements

Pruning and leaf picking can reduce water evaporation and alleviate the water supply pressure of injured roots

It is appropriate to pick 1 / 3 of the amount of branches and leaves, otherwise it will reduce the transpiration tension and make it difficult for the root system to absorb water

Other tips

In the process of Magnolia grandiflora transplantation, in order to promote the recovery of roots, efficient rooting agent "fast rooting" can be used

After planting, support wood shall be set to fix the trunk to prevent shaking and damage to the root system. A tripod made of Moso bamboo or other materials with a length of 3m to 4m can be selected for fixation
