Preparation of Magnolia grandiflora before grafting
Grafting time
From the first and middle of March to the first ten days of April, you can choose the weather with mild climate and no rain on cloudy days p>
Selection of Rootstock
Magnolia, Magnolia, Magnolia officinalis, etc. can be used as rootstock seedlings for grafting Magnolia p>
Scion selection
The branches of Magnolia grandiflorum with strong growth and full buds in the previous year or that year can be used as scions, and it is better to pick and connect at the same time. After cutting off the leaves, the scion only needs to leave a little petiole and keep 2-3 bud mouths. To prevent the scion from drying, cover the scion with a wet towel or straw p>
Specific operation
When grafting, cut the rootstock from the height of 4-5cm away from the rhizome, cut it into an oblique angle on the cutting mouth, and cut the lower cutting mouth of the scion mouth into a 45 degree angle with a grafting knife. After cutting the rootstock and scion, immediately insert the scion into the cutting part of the rootstock, align the cambium of the two, and bind the scion and rootstock with plastic cloth or bamboo strip. After grafting, cover it with fine soil and press the lower part tightly p>
Management of Magnolia grandiflora after grafting
1.after 15 days of grafting, check whether it survives. If the scion withers and the cortex wrinkles and shrinks, it indicates that the scion has died, and it should be repaired quickly; If the scion is fresh and the cortex has sufficient water, it indicates that the scion has survived p>
2.the grafting wound will heal in about 20-25 days. When the bud grows to 2-3 leaves, weed in time, remove the mother seedling and avoid colliding with the scion. In the later stage, we should often weed, fertilize and water, and spray Bordeaux liquid to prevent and control diseases and pests p>
3.plastic strips and bagging shall be removed in time after scion germination< span>
