Survival method and cutting time of Magnolia grandiflora cuttings 1
The cutting time of Magnolia grandiflora is from May to June every year. When the temperature is suitable, the survival rate of cutting can be improved, or it can be postponed for one week according to the local climate. However, it can't be carried out in Xia Dong in two seasons, and the temperature is too extreme, which is not conducive to plant growth.
2. Branching therapy
Magnolia grandiflora should choose healthy and disease-free branches for cutting. Such branches are conducive to survival, and the length is preferably about 20 cm. Then, the top branches and leaves of the branches should be kept and the rest should be removed. The lower end should be obliquely cut at 45 degrees and soaked in rooting solution for two hours.
3. Cutting method
After the branches of Magnolia grandiflora are treated, the fertile and loose soil is prepared, and the branches are inserted, so as not to damage the branches as much as possible in the process, and then the gaps are filled and compacted by hand, so that the branches are closely attached to the soil, which can improve the survival rate of cutting.
4. Preventive measures
After the cutting of Magnolia grandiflora is completed, it should be placed in an environment of 20-25 degrees, and the ground should be sprayed to increase the air humidity and avoid direct sunlight. When the humidity is too low, the plants are short of water and the leaves turn yellow, which reduces the survival rate of cutting.
