What is the cutting propagation method of Ilex cornuta without spines?
The editor will introduce the cutting propagation method of Ilex cornuta without spines and related topics about the cultivation techniques of Ilex cornuta, followed by a comprehensive introduction.
Methods of grafting and shaping between Ilex cornuta with spines and without spines.
Ilex cornuta without spines is a natural variant of Ilex cornuta, an evergreen shrub or small tree with dense branches and leaves, unique leaf shape, and glossy dark green foliage. Through pruning and shaping, it can be transformed into large trees, spherical shapes, and tree-like bonsais, making it an excellent ornamental species for fruit, leaves, and shape. However, due to the influence of different regional climatic conditions, the survival rate and growth rate of Ilex cornuta without spines are relatively low, posing many difficulties for landscaping engineering. Ilex cornuta with spines has strong adaptability, high survival rate, and is耐修剪 (prune-resistant), with strong germination, but its leaves have sharp spines that can easily injure people and its ornamental value is inferior to that of Ilex cornuta without spines.
Using Ilex cornuta with spines as the rootstock and Ilex cornuta without spines as the scion, the grafted Ilex cornuta not only has the good ornamental value of Ilex cornuta without spines but also significantly improves the survival rate and growth rate, with round leaves that are less likely to injure people and are easy to prune and shape, making it an ideal species for landscaping.
Firstly, select a healthy, 2-3-year-old Ilex cornuta with spines with a diameter of 6-8cm as the rootstock, and choose a disease-free and pest-free branch of Ilex cornuta without spines about 1cm in diameter and 5cm in length, with a node and a relatively straight shape as the scion. Cut the bottom of the scion into a wedge shape with a sharp knife, keeping the cutting surface smooth.
Secondly, cut the Ilex cornuta with spines as the rootstock about 20cm from the ground at a smooth bark area, make a 3-5cm long incision on one side of the rootstock section, then cut 3-5 pieces of Ilex cornuta without spines of 0.8-1.5cm in diameter to match the length of the rootstock incision, insert the cut end of the scion with the cutting surface into the rootstock incision, and align and press them tightly against each other's cambium layer.
Then, apply plant wound healing agent on the exposed cambium area to significantly improve the grafting survival rate. The plant cut can quickly form a protective film with moisture-retaining and moisturizing membrane permeability, preventing the loss of moisture and nutrients. The addition of cytokinins and cytokinin promotes the regenerative capacity of callus tissue, accelerates wound healing, and prevents contamination, disinfects, and preserves the plant wound without burning the tree body, and is resistant to rain wash after film formation.
In order to make the cambium layers of the rootstock and scion adhere closely, wrap the scion and rootstock tightly with tape instead of plastic film at the grafting site. At the same time, shade the rootstock and scion for maintenance, which can be done by setting up a 50% shade net.
Fourth step: After the scion has taken root, prune and shape the grafted bonsai.
