The latest course on techniques and methods of grafting Osmanthus fragrans with tassel trees

The flowering period is from April to June, and the fruiting period is from September to October. The soil requirements are not strict, neutral, slightly acidic, slightly alkaline can adapt. Osmanthus fragrans grafted with tassels has strong affinity and grows well. Osmanthus fragrans potted plants cultivated with tassels stumps can be placed at home. The grafting time is usually when tassels sprout.

splice method

When grafting, cut the appropriate part of the rootstock, select the smoother side of the bark, slightly cut vertically with xylem, and cut 2 cm to 3 cm deep. The scion is chamfered to a length of 2 to 3 cm and then chamfered to a length of 1 cm on the reverse side, while retaining 2 to 3 pairs of buds and cutting the branches. Immediately insert scion into rootstock so that cambium bonds intimately.

For big rootstock, several scions can be connected. After scion is inserted, it is immediately bound and fixed with plastic film strips, and at the same time, it is covered with small plastic bags for moisture preservation and heat preservation.

ventral connection

Belly grafting is a branch grafting method without cutting off the rootstock crown. During grafting, the rootstock is obliquely cut into the rootstock at an inclination angle of 20 ° to 30 °, reaching 1/3 to 1/2 of the rootstock diameter. then both sides of the lower end of the scion are respectively cut into inclined surfaces of 1cm to 2cm, two to three opposite buds are reserved, the scion is inserted into a cutting edge of the stock, aligned with a cambium layer on one side of the stock, bound by plastic film strips, kept moist and kept warm.

cleavage method

When grafting, the rootstock will be cut into a plane at a certain height, and then split vertically in the center of the rootstock section with a splitting knife, the depth is 4 cm to 5 cm, and then insert the knife back into the incision to make it open. The scion is selected from 2-year-old branches with 4 to 5 pairs of buds, both sides of the scion are cut into equal wedges, then the scion is inserted into the rootstock incision, so that the two layers are closely combined, and the scion is firmly bound by plastic film strips, and at the same time, a plastic bag is sleeved and tightened, so as to keep moisture and heat.

skin joint

When the tassel sap has begun to flow, the bark is easy to peel off. First, cut a slope of 2 cm to 3 cm long at the back of the scion bud 1 cm to 2 cm, and then cut a small slope about 0.6 cm long at the tip of the slope. Then cut and flatten the rootstock where it is needed, then select the smooth part of the rootstock bark and cut it vertically from top to bottom, reaching the xylem deeply, about 1.5 cm long, gently pick open the cortex along the incision to both sides, and insert the scion.

If the rootstock is coarse, several scions can be grafted. After scions are inserted, they are bound and fixed with plastic film strips, and then covered with plastic bags for heat preservation and moisture retention.

abutment

From May to July every year, tassels and osmanthus fragrans are cut off at appropriate heights of 5 cm to 10 cm respectively, and two inclined ports with a depth of 1/4 to 1/3 of the trunk diameter are aligned with the cambium and bound with plastic film strips. After one month of grafting (20 days for the fastest), the lower part of scion and the upper part of rootstock can be cut off.
