"two methods" of grafting for planting Chinese Chestnut

Now the "abdominal connection method" and "cutting method" are introduced as follows:

Ventral grafting is a kind of grafting method with no cross section in autumn. This method can be used for height grafting of seedlings and big trees.

The specific measures are:

1. Open the anvil. Cut a knife down on the straight side of the rootstock about 7 cm from the ground, about 3 cm long, slightly woody, forming an incision between the rootstock and the stem.

two。 Cut the scion. First cut the panicle into an ear segment with two buds and a length of 4ml / 6cm. The first knife is to cut a 3.5cm long surface at the bottom of the scion, straight, smooth and deep into the xylem. The second knife cuts a short Maltese-shaped slope with a length of 0.5ml cm on the reverse side of the long cutting surface at an angle of 40 degrees with the long cutting surface. The third knife, in the upper part of the Maltese-shaped bevel, cuts a flat cutting surface that is 2.5 cm long and parallel to the long cutting plane. Then insert the scion into the cut of the rootstock, the position is long cut inward, cover the short slope of the scion and the upper flat cutting surface, so that the cutting surface of the rootstock and ear are closely healed, and the wound of the rootstock and ear is sealed and fastened with plastic film. To survive the grafting, when the scion sprouts in spring, cut off the tail of the rootstock 0.5 cm from the upper end of the interface of the rootstock and cut the bandaged plastic belt with a knife to loosen it.

The cutting method should be used when the sap of Chunwei rootstock is not yet flowing or when the rootstock is small.

1. The method of opening the rootstock: cut and flatten the cut where the rootstock is about 5cm straight from the ground, gently cut a short slope of about 0.1cm long from bottom to top on the straight side of the section, and cut a 3.5cm long side vertically between the xylem and phloem of the short slope to form a cut between the rootstock and the stem of the seedling. two。 Scion cutting method: same as abdominal grafting method. When grafting, the cut scion is also inserted into the cut of the cutting surface of the rootstock. If the size of the rootstock and the ear are not consistent, one side can be aligned to form a close connection between the two. After grafting, the wounds of anvil and ear are sealed and wrapped with plastic tape, but the scion buds should be exposed.
