When modeling plant compositions,their possible maximum dimensions must be considered. So, shrubs and trees tend to grow, grow in size and gain weight. At the same time, knowledge of the main types of rhizomes of plants is of no small importance. So, the root system is a kind of crown underground. In some plants it is pyramidal, and in others it is spherical.
The roots of various plants should not be toooverlap, grow together or intertwined. It is unacceptable that they compete for food and water, and with their growth they could run into various obstacles represented by communications or a foundation.
The root system in form is not alwaysmirror image of the crown shape. So, the erroneous opinion is that the plant with a balanced and even crown has the same roots. Sometimes they cannot go beyond the projection of the upper part of the plant (an example is cherry felt), and sometimes with spreading branches the plant has a taproot. There are species of plants in which the crown has a columnar shape, and the root system of plants is superficial.
In addition, the root system of some plantstends to change with their age. For example, Robinia pseudo-acacia at a young age has a fibrous root system, and in adulthood it has a superficial root system. Soil-ecological conditions are also important: for example, the root system of Scots pine has a deep rod form, and when grown in moist, heavy soils, it is fibrous.
The formation of the rhizome of plants is carried outsimilar to the formation of their ground part. Basically, such operations are carried out in nurseries. The procedure is as follows: once every 5 years, depending on the species, the plants are subject to “transshipment”. In other words, they are dug out and form both the ground and underground parts at the same time. Cropped roots begin to branch and, thus, a fibrous form is obtained. That it is quite convenient when boarding or transporting. It is easy to place it with a good straightening in the landing hole. But in the case of a core form, such a root cannot be bent or twisted.
The latter type is characteristic of the species thatgrow on sandy soils where the groundwater is very deep. Also, these plants are highly resistant to wind. That is why we can observe how mast pines stand “like soldiers” on sandy knolls, and forest spruces, which have sailing crowns and surface roots, are blown down quite easily by the wind.
The root system also works as awater pumps. However, this does not mean that it should be deep in the ground and reach the aquifers. In the case of a close location of the water, the form of the rhizome can be either fibrous or surface. An example is birch in adulthood, which has a medium-sized root system (between the surface and fibrous), and with its underground system, up to 200 liters of water is pumped out of the ground. However, with all its “insatiability” this plant is of no small importance for swampy areas.
It is necessary to carefully consider the issue of location.planting plants. The rule is quite simple: plants with a core system are intolerant of high water levels, and with a fibrous and superficial one, they have a relative tolerance for water.
Another problem may be planting.plants near buildings and structures. In the case of the presence of a surface system, there is the likelihood of a plant stumbling onto a foundation, and a rod-like and fibrous plant — on communications in the ground. It is for this that certain norms serve that help to avoid such situations.
