How to propagate camellias through grafting
The editor will tell you about the related knowledge of how to propagate camellias through grafting, and then introduce to netizens.
Camellias, oil camellias, or camellia japonica can be used as rootstocks. It can be divided into two methods: branch grafting and bud grafting. Branch grafting can be further divided into close grafting and split grafting; bud grafting can be divided into seedling rootstock grafting and branch bark撕皮 grafting, as follows:
1. Close grafting
There are four operation methods: bare root seedling close grafting, soft branch close grafting, hard branch close grafting, and water insertion close grafting.
Bare root seedling close grafting can be carried out throughout the year, but the most suitable period is from early March to early April. Use 3-year-old or older seedlings with many branches as the rootstock, and 1 to 2-year-old high-quality seedlings with a height of more than 10 centimeters as scions. First, wash the root of the scion clean with water, and then make a vertical cut of 1.5 to 2 centimeters in length on a one-year-old strong branch of the rootstock and the smooth middle part of the scion. The depth should be about 1/4 of its diameter, with smooth and similar widths. Quickly match the incisions, align one side of the cambium layer, and tie securely with a plastic strip. Then, cover the root of the scion with a small pot with a diameter of 10 centimeters, add cultivation soil to the small pot, and water thoroughly.
In addition, there are soft branch close grafting, hard branch close grafting, and water insertion close grafting.
2. Seedling rootstock grafting
Generally, sowing is carried out two months before grafting, and when the seedlings are 4 to 5 centimeters tall, they can be used for grafting. When digging the rootstock, wash it clean with water and keep it moist.
Select semi-woody branches of the current year that are similar in thickness to the rootstock, first make oblique cuts from the lower sides of the leaf petioles, about 0.6 to 0.8 centimeters long, forming a wedge shape, and then cut off 0.2 centimeters above the bud.
Place the seedling rootstock flat on the grafting board, cut off the long main root, cut off the stem 1 to 1.5 centimeters above the cotyledon, and then make a longitudinal cut along the cotyledon joint line, the depth of which is consistent with the oblique surface of the scion. Quickly insert the scion into the cut of the rootstock, align one side of the cambium layer, and tie it securely with a plastic strip.
After the grafting is finished, the grafted seedlings can be directly planted in seedbeds, wooden boxes, and flowerpots, using conventional cultivation soil, and water thoroughly after planting.
