What is the method of cutting the bark off the trunk and wrapping it with nutritious soil to take root?

Cut the bark off the trunk and wrap it with nutrient soil, and it will take root. This is layering propagation.

Layering, also known as layering, refers to burying the branches and stems of plants in the soil, or wrapping the parts that need layering in the trees with soil or other substrates to make them take root and then cut them off to become independent new plants. This method is called layered propagation. This method is often used to propagate woody flowers, such as Chinese rose and Milan.

The stratification time varies with plant species and local climatic conditions. Generally, the best layering period of deciduous plants is mostly in the winter dormancy period, or at the beginning of growth from February to April in early spring. After August in autumn, stratification can also be carried out. Because the branches are mature at this time, the nutrients in the branches are sufficient, and it is the easiest to take root.

The rainy season is suitable for evergreen plants, because the layering is easy to take root and has sufficient growth period, which can meet the wound healing, rooting and growth of layering. However, when the liquid flow is strong, attention should be paid to layering, and it is not suitable for cutting or carving.

Grafting is one of the artificial propagation methods of plants. That is, the branches or buds of one plant are grafted to the stems or roots of another plant, so that the two parts connected together grow into a complete plant. Grafting methods are divided into branch grafting and bud grafting. Grafting by using the function of injured callus of plants.

Grafting is a kind of vegetative reproduction in asexual reproduction. When grafting, the scion should be closely combined with the cambium of rootstock to ensure the survival of the scion. Grafted branches or buds are called scions; Grafted plants are called roots or edible wood. Generally, seedlings with 2 ~ 4 buds are selected as scions, which become the upper part or top of the plant after grafting, and rootstocks become the roots of the plant after grafting.

When grafting, the cambium of the two injured surfaces are close together and tied together. As a result, due to cell proliferation, they heal each other and become a whole connected with vascular tissue. This is the principle of grafting.

The main factor affecting the survival of grafting is the compatibility between scion and rootstock, followed by grafting technology and post-grafting management. The so-called affinity refers to the ability of scion and rootstock to be identical or similar to each other in internal organizational structure, physiology and heredity, so as to be able to combine with each other.

High affinity and high grafting survival rate. On the contrary, the survival rate is low. Generally speaking, the closer the genetic relationship between plants, the stronger the affinity. For example, apples are grafted on sand fruits; Pear is connected with Li Du pear and Qiuzi pear; Persimmon grafted with black dates; Walnut and Juglans mandshurica have good affinity.
