Root system of various plants
When modeling compositions from plants,it is necessary to take into account their possible maximum dimensions. So, shrubs and trees tend to expand, increase in size and gain weight. At the same time, knowledge of the main types of plant rhizomes is of no small importance. So, the root system is a kind of crown beneath the ground. In some plants it is pyramidal, while in others it is spherical.
The roots of various plants should not be toooverlap, fuse or intertwine. It is unacceptable that they compete for food and water, and with their growth they might come across various obstacles presented by communications or the foundation.
The root system in form is not alwaysmirror image of the crown shape. So, the erroneous opinion that a plant with a balanced and flat crown has the same roots. Sometimes they can not 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 core root. 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 plantshas the property of changing with their age. For example, robinia psevdokaktsiya at a young age has a fibrous root system, and in adulthood - superficial. Of great importance are soil-ecological conditions: for example, the root system of Scots pine has a deep rod shape, and when grown in moist heavy soils, it is friable.
Formation of plant rhizomes is carried outsimilar to the formation of their ground part. Basically, such operations are carried out in nurseries. The procedure is as follows: every 5 years, depending on the species, the plants are subject to "transshipment". In other words, they are excavated and form both a ground and an underground part. The truncated roots begin to branch and, thus, the furry form is obtained. It is convenient for landing or transportation. It is easy to place with good expansion in the landing pit. But in the case of the rod shape, such a root can not be bent or twisted.
The latter type is peculiar to those species thatgrow on sandy soils, where the groundwater is very deep. Also, such plants are highly resistant to wind. That is why we can observe how mast pines stand "like soldiers" on sandy hillocks, and forest spruce, having a sail crown and surface roots, winds down quite easily.
The root system also works as awater pumps. However, this does not mean that it should be deep in the earth and reach the most aquifers. In the case of close water, the shape of the rhizome can be either friable or superficial. An example is a birch in adulthood, having a root system of the middle type (between surface and friable), and with the help of its underground system, up to 200 liters of water is pumped from the soil. However, despite its "insatiability" this plant is of no small importance for the swampy terrain.
Care must be given to the question of the placeplanting plants. The rule is quite simple: plants with a rod system are intolerant to a high water level, and with a friable and superficial have relative tolerance to water.
Another problem may be plantingplants near buildings and buildings. In the case of a surface system, there is a possibility of planting the plant on the foundation, and rod and friable - on the communication in the ground. It is for this purpose that certain norms serve that help to avoid the occurrence of such situations.
