Bonsai teaching: how to dwarf black pine seedlings teach you

Black pine is not as tall as other tall trees in the field, but if it is to be made into a bonsai tree, it is often not suitable for the shape of the tree to be too tall. But the ornamental value of black pine bonsai is very high, but as potted plants, we often need some dwarfing treatment, even if piled down, is no exception. Therefore, the dwarfing of Pinus thunbergii is usually the first problem we deal with.

Wild quality Pinus thunbergii is rare, especially short stakes suitable for potted plants. Even if a suitable short pile is found, we should pay attention to the methods and techniques in the process of excavation, otherwise it will affect the survival rate caused by improper operation. Therefore, how to ensure the survival rate in the process of black pine mining is also very important. At the same time, digging short piles is also a way to realize Pinus thunbergii dwarves.

But before digging the black pine pile, we need to choose the right mining time in advance. This is also the first condition to improve the survival rate of black pine pile. It is usually carried out in autumn, and if the soil is excavated, it will help to improve the survival rate. However, the mining area is often affected by the regional environment. Take Jianghuai area as an example, it is usually suitable for cold season and rainy season. Other areas can be mastered or postponed in advance according to the local reality.

Usually, the time of mining is in the dormant period of Pinus thunbergii, and the growth factor of the tree is still in a quiet state. However, once the temperature rises, the short pile may soon regain consciousness and return to normal growth. This is very disadvantageous to the wound healing and new root sprouting in the process of old pile excavation.

But if the excavation is carried out early, the old pile will be in deep dormancy for a long time, when the wound caused by the root of the tree is difficult to heal and will die. Even if the downhill pile is successfully laid on the basin, its survival effect is also worrying. Most of the important branches are dry, dry, the growth condition is not good, lost the cultivation value.

Of course, it is unwise to dig too late, because the sap of the tree circulates normally after the temperature warms, and the stump comes back to normal growth. At this time to the root of the tree caused too much damage, the wound did not dry, healing will occur decay, at this time is the active period of pathogens, so it is easy to infect the wound, but also not conducive to the survival of hemorrhoids.

In order to improve the survival rate of downhill piles, we should not only choose the appropriate time, but also be careful in the process of excavation. It is suggested that the soil ball excavation method should be adopted, which is an important factor to improve the survival rate of black pine dwarf pile. Of course, if it is sandy soil, we can not use soil balls or less soil. For black pine over 3 years old, if the soil is thick, it is not easy to survive even if the soil ball is taken away. Therefore, soil ball excavation is a necessary means to improve the survival rate.

The smooth transportation of black pine short piles is also very important. It is usually necessary to cut off too many sticks to facilitate transportation, but at the same time avoid excessive water loss. Therefore, we usually need to wrap short piles and soil balls with plastic film before transportation. If necessary, we also need to wrap the main part of the plastic bag in the plastic bag.
