Meadow formed in three stages.First annual species germinate and creeping grasses.All this vegetation is characterized by shallow rooting, and its roots, creeping shoots and roots form the surface of the turf.Once the seedlings will become thick and forms the first layer of humus, there ryhlokustovye views.They are rooted more deeply annual and use the nutrients found in the soil layers to be.In the last stage there is a further "thickening" of plants and soil acidification.As a result, the roots of certain grasses are no longer getting the required amount of air.Thus, some meadow plants die.In their place are beginning to sprout ordinary grass species.In wet areas appear rushes and sedges.
should say that meadow plants are quite rich community that is dynamic.Grass compete for light, nutrients and water to each other.All occupy the top tier of light-loving plants meadow.In the lower tier of the species are located, excellently carrying almost complete absence of light.
It should be noted that the composition and type of meadow vegetation depends not only on human activity, but also on the characteristics of the terrain: river flooding, soil quality, wind direction, the ground water level.Are of great importance and inhabiting countryside birds and insects involved in the transport of seeds.
Based on these criteria are divided into upland meadows, mountain pastures, floodplain, wetlands reclaimed, fens, meadows.Filler (floodplain) of the territory - a valley or a place where there is a spill of water or soil podmokanie.At such sites, meadow plants represented about fifty species.
The top tier is possible to see representatives of sedge.They perfectly acidic soil.The lower tier is represented by such species as moneywort (creeping plant of the family Primulaceae, aka monetchaty loosestrife), and others.
Most of all meadow areas - the so-called dry lands.It occurs on average about eighty species of herbs and plants.Among them, clover, forage, low and high grass.Almost everywhere there are leafless panicles of meadow bluegrass, which is characterized by an extensive root system.Because of this, a sufficiently durable turf with a certain resistance to trampling.
among meadow plants should also be noted fescue.It is distinguished by the variety of morphological characters.For example, red fescue is resistant to frost and under the ice crust can survive for two months.Flowering This plant in June.Leaves fescue grow very quickly in the summer - up to four millimeters a day.The plant is resistant to trampling, loves the light, carries the full flooding with water for ten to fifteen days.
the clearings there are many different plants used by man for agricultural purposes.The forests and various weed species.Some wild plants are very attractive in appearance.Such species include, for example, blue cornflower.Wildflowers usually grow near enough inconspicuous representatives of flora.Such species include, for example, wheat grass, horsetail, and others.
Some plants meadows contain hazardous toxic compounds.There are also representatives of the rich in nutrients and proteins.These plants include alfalfa, sweet clover.The latter, among other things, is rich in vitamins E and C, it contains a set of coumarin compounds used in the flavoring of tobacco.
