- loose shrub rhizome plant of winter type, forms a large number of shortened shoots capable of multiple regrowth during the growing season. This determines the ability meadow bluegrass to intensive pasture use (5-6 cycles or more per season). It is well eaten by livestock, better mixed with other herbs, so it should not be sown in its pure form on pastures.

In spring, it starts growing early and develops rapidly. Grows well after grazing, giving green fodder until the end of the growing season. Basal leaves of the main shoot and leaves of vegetative shoots are abundant, dark green, more or less folded lengthwise, with a prominent midrib, smooth or inversely rough in the upper part, shortly pointed, narrowly linear. The width of the leaves reaches 4 mm; uvula obtuse, 0.5-2 mm long. Generative shoots are straight, smooth, 30-90 cm high. Panicle compressed before and after flowering, broadly pyramidal during flowering, up to 20 cm in length. Spikelets crowded greenish, elongated-elliptical. At the base of the fruit there is a bundle of numerous whitish hairs. This is a typical mesophyte, but it is adapted to exist in conditions with less moisture. Prefers moderately moist, rather fertile, aerated sandy and loamy soils. Grows well on more fertile varieties of peat soils. Bluegrass meadow withstands prolonged flooding with melt water. Grows best when laid down ground water at a depth of 0.5-1.0 m. It has a negative attitude towards soil salinization. Very sensitive to soil acidity. Grows best in soils rich in lime. Highly susceptible to powdery mildew and rust. It is undemanding to temperature conditions, but during the heat, a long summer drought, plants can burn without watering. It is characterized by high winter hardiness. Excellently withstands harsh winters and frosts during the growing season. Bluegrass meadow- perennial grassroots grass. Thanks to their biological features meadow bluegrass forms and sustainably preserves high-quality grassy coverings with dense, intensely green herbage and strong turf. Bluegrass meadow stops growing in late autumn, much later than other lawn grasses, and goes green under the snow. Differs in durability. Under favorable conditions, it vegetates in artificial grass stands for several decades. herbage meadow bluegrass tolerant of moderate trampling. herbage meadow bluegrass does not tolerate soil drought, but the rhizomes are very viable, so reseeding lawns under these conditions, it is not necessary: ​​with the resumption of irrigation, the herbage grows back. Bluegrass meadow suitable for creating parterre and ordinary lawns.

Bluegrass meadow (Poa pratensis L.) (American name Kentucky bluegrass) - grassroots perennial rhizomatous-loose bush grass. Prefers moderately moist, rather fertile, aerated sandy and loamy soils. It is not picky about temperature conditions. It is characterized by high winter hardiness, excellently withstands harsh winters and frosts during the growing season. Differs in durability, the herbage is hardy to trampling, forms grassy coverings of high quality with dense intensively green herbage and strong turf. Bluegrass meadow is an indispensable component sports lawns, only he is responsible for the wear resistance of the lawn.

The bluegrass meadow is not resistant to drought, at this time it goes into a state of rest. In this case, the leaves and stems turn yellow and die. During the dry period, watering for lawns from meadow bluegrass required.

Bluegrass meadow prefers open, sunny places.

It is a highly productive component in the composition fodder grass mixtures: Green Deer Agro "Combi", "Haymaking" And "Grazing"

Sometimes, the most unexpected qualities and useful properties can be found on closer examination in the most common meadow herbs found everywhere. What does meadow bluegrass hide in itself, where it grows and for what purposes it is used by a person - a new look at familiar things.

Bluegrass - herbaceous plant found both in meadows and forests. This representative of the flora is endowed with creeping and underground shoots that are capable of forming thick, loose turfs.

plant description

plant part	Botanical features
stems	Height from 30 to 90 cm, less often 10-20 cm, smooth, rising
Leaves	Narrowly linear, up to 4 mm wide, flat, smooth or slightly rough. The tongue is blunt, reaches a length of 0.5 - 2 mm. Leaf venation is linear.
Panicle	Length - up to 20 cm. The shape is pyramidal or oblong. The panicle is multi-spikelet, equipped with rough branches arranged 3-5 together.
Spikelets	Egg-shaped, length - 3.5 - 6 mm. With 2-5 flowers. Usually green, rarely purple. Spikelet scales are almost identical, pointed.
Fetus	The fruit has a grain.

It cross-pollinates but is also capable of self-pollination. The maximum development of the plant reaches the 2nd, 3rd year of life.

The flower formula gives an idea that the plant is rather nondescript during the flowering period. Flowering - once a year, but if the weather conditions are favorable, it may bloom a second time.

Varieties and varieties

Perennial grass is found in several varieties:

1. Bluegrass meadow - grows well, resistant to trampling and drought. Does not tolerate frequent haircuts.
2. Common bluegrass - grows in turfs. Not resistant to cold and trampling.
3. Bluegrass forest (oak) - grows well among other cereals, grows well in dense shade. He does not tolerate frequent haircuts, he is exhausted from it and falls out.
4. Bluegrass annual - color until frost. It tolerates a haircut well, but the heat has a negative effect on it: the plant turns yellow and begins to fall out.

Among more than 300 varieties of plants, several of the most popular are distinguished:

• Dolphin - famous lawn grass, which grows well in shady areas. This plant is dark green, unpretentious;
• Connie - great for decorating the space around flower beds, creating flower mixes;
• Midnight is a variety with increased resistance to trampling. An excellent option for sowing a football field. The plant is not afraid of any pests and temperature changes;
• Compact - artificially bred variety, characterized by drought resistance and disease resistance;
• Platini - unpretentious, grows very quickly. Wear-resistant, withstands increased loads;
• Balin is a frost-resistant variety that tolerates winter well, remaining green. Sports fields are sown with this type of bluegrass.

Plant distribution regions

The natural distribution area of ​​the bluegrass meadow is considered to be the temperate zone of the northern hemisphere. But today this plant can be found everywhere; due to its unpretentiousness, it is cultivated on all continents. Bluegrass meadow grows even in Antarctica, where it was accidentally brought in the middle of the 20th century.

In our country, this herbaceous cereal is found in the Caucasus, Siberia and Far East.

What type of root system does the plant have

Meadow grass meadow is endowed with a high aggressiveness of the root system.

It has a fibrous root system, most of which is in the upper soil layer. Together with rhizomes, it forms a dense pasture-resistant turf.

Areas of use

Meadow grass meadow is indispensable as a component in the composition of dry and fresh pastures and meadows sown with a mixture of forage grasses. This plant accounts for 5-10% of the total composition. After sowing, the first shoots can be noted as early as 7-8 days. The average germination is about 27%. It is necessary to collect seeds in July and August, before the onset of full maturation. Before sowing seeds, they should be rubbed through a sieve.

Bluegrass is cut for hay. Its value, as a fodder crop, lies in the low water content in the composition and a large amount of protein substances. Cattle love meadow bluegrass both dry and fresh. From 1 hectare you can collect about 1600 kg. hay.

Bluegrass is also suitable for pastures. In North America, this cereal is considered one of the most valuable forage crops, second only to timothy.

The plant is widely used as a cereal, which is sown with airfields, sports fields, football fields. It will make excellent lawn grass.

IN traditional medicine bluegrass meadow is not used.

Bluegrass meadow like lawn grass

The plant is widely used as a lawn grass. But such a cereal requires special irrigation. After mowing, it grows evenly and smoothly. On the lawn during mowing, it is recommended to leave at least 2-3 cm.

Bluegrass is a hardy plant. If the weather conditions are favorable, then this grass can be stored in grass stands for up to 15 years. Incredibly resistant to toxic substances, even if you have to grow in close proximity to sources of pollution.

Important! Bluegrass meadow does not tolerate high acidity of the soil and salinity of the earth.

Resistant to prolonged trampling.

After sowing the lawn, constant watering is required at first. It is necessary to moisten the soil every day for 10 minutes. Continue similar actions until the first shoots, then water depending on weather conditions.

During the entire first month after sowing the crop, it is impossible to walk on the lawn.

Bluegrass meadow - the best cereal for creating lawns. Thanks to a range of useful properties, such as unpretentiousness, frost resistance, rapid renewal, responsiveness to mineral fertilizers, the culture is actively used by gardeners

Syn.: Uriankhai bluegrass, jointed bluegrass.

Poa meadowa is a perennial plant of the genus Poa (lat. Poa) with creeping underground shoots, flat narrow leaves and a multi-spike panicle. This is the earliest cereal, it is cultivated throughout the world and is considered the most valuable plant for pastures, hay and lawns.

In medicine

Bluegrass meadow is included in the Register medicines Russian Federation as part of the medical immunobiological preparation "Allergen from meadow grass pollen", which is used for the diagnosis and treatment of hay fever, seasonal allergy to the pollen of some plants. The disease manifests itself at the same time of the year and is accompanied by a runny nose, conjunctivitis, dermatitis, cough, as well as irritability and fatigue.

Contraindications and side effects

The use of the drug from the pollen of meadow bluegrass is contraindicated in children under 5 years of age, pregnant and lactating women. The allergen is not recommended for tuberculosis, severe bronchial asthma, malignant neoplasms, mental and autoimmune diseases, immunodeficiency, systemic connective tissue diseases, severe forms of atopic eczema, exacerbations of an allergic disease, acute infections, cardiovascular diseases and chronic diseases in the acute stage. Before using the drug, a specialist consultation is necessary.

In landscape design

Meadow grass meadow is the main component of grass mixtures for growing high-quality garden, park and home garden lawns, as well as for creating children's and sports grounds. The grass is quite durable, recovers quickly and tolerates trampling well. In addition, due to the great viability of the rhizome, it is resistant to drought and frost. Another reason for the popularity of bluegrass among gardeners is its ability to fill in bumps and cover problem areas of the earth. At proper care this grass can grow for several decades in a row. The most famous bluegrass varieties are Sobra, Midnight, Blackberry, Konni and Dolphin.

In agriculture

Bluegrass meadow is one of the most valuable pasture plants; in North America, in terms of yield and nutritional value, it is in second place after timothy. In Russia, it is also in demand, its share in the mixture of forage grasses sown is 5-10%. The plant prefers alkaline soils, tolerates flooding, frost and drought.

Under good conditions, bluegrass grass can last 10 years or more. In terms of yield, cereal occupies one of the first places; up to 350 centners of green mass are harvested from 1 hectare of land. Hay from this plant is rich in proteins, proteins and vitamins, tender and nutritious food is eaten with pleasure by all types of livestock. In addition, bluegrass is used for silage, top dressing, haylage and grass meal.

Classification

Bluegrass meadow (lat. Poa pratensis) is one of 530 species of the genus Bluegrass (lat. Poa), which is part of the Cereal family (lat. Poaceae).

Botanical description

Bluegrass meadow is a perennial grass growing in dense, loose turfs. The creeping fibrous rhizome penetrates the ground to a depth of 100-130 cm. The stems are smooth, thin, slightly leafy, 30-100 cm high. The leaves are flat, narrow-linear, smooth or slightly rough, 1.5-4 cm wide. The uvula is rounded, blunt, 0.5–2 mm long. The inflorescence is a sprawling, pyramidal or ovoid panicle up to 25 cm long. The twigs are rough, sitting together in 3-5 pieces. Spikelets ovoid, 3-6 mm long, 3-5 flowered. The color of spikelets is green, less often purple. Spikelet scales pointed. The lower lemmas are lanceolate, with 5 pubescent veins and numerous connective fibers at the base. On the keel of the upper lemmas there are a small number of elongated spines, turning into hairs at the base. The fruit is an oblong trihedral light yellow caryopsis without an awn, 2-3 mm in length. The approximate weight of 1000 seeds is 0.3 g.

Spreading

Meadow grass meadow most often grows in fields, meadows, forest edges, along reservoirs and roads. The natural distribution area of ​​bluegrass is the temperate zone of the Northern Hemisphere, and it is cultivated on all continents. Grass can be seen even in Antarctica; in the middle of the twentieth century, the seeds of bluegrass were accidentally brought to the largest peninsula of the coldest continent. In Russia, this plant can be found in all regions, it grows in the European part, the Caucasus, Siberia and the Far East.

Distribution regions on the map of Russia.

Procurement of raw materials

Since the bluegrass is one of the earliest types of grasses, it is mowed down for making hay in the first place. After that, the plant is dried, raked into rolls, dried and taken to storage in a dry, ventilated room. For a new sowing, meadow bluegrass seeds are harvested in the middle of summer. They easily get into lumps, which are then rubbed through a sieve.

Chemical composition

The composition of bluegrass includes proteins, fiber, fats, starch, sugars, nitrogen-free extractives, lysine, methionine, cystine. The plant is rich in potassium, calcium, iron, copper, zinc, manganese, carotene, vitamins D, E, B 1 , B 2 , B 3 , B 4 , B 5 .

Pharmacological properties

Meadow grass meadow is used in medicine as an allergen and is used to diagnose and treat hay fever. The active substance of this drug is a water-salt extract of protein-polysaccharide complexes obtained from plant pollen.

Application in traditional medicine

The meadow grass meadow plant is not used in traditional medicine.

Historical reference

In America, all representatives of the genus Bluegrass (lat. Poa) are called "bluegrass", which literally translates as "blue grass". Since the meadow bluegrass species (lat. Poa pratensis) is most widespread in the state of Kentucky, it received the name "bluegrass Kentucky", and the unofficial nickname "Bluegrass State" was assigned to the state itself. This story continued in the 20th century, when native Bill Monroe founded a new genre in American music that continued the tradition of country music. The style of Bill Monroe and his group "Blue Grass Boys" was unique, but for a long time did not have a definite name. Only in 1965, the musicians gathered at the festival decided to call this genre "bluegrass", in honor of the founder's homeland and the name of his group. So meadow bluegrass entered the history of a whole direction of American music, now known all over the world.

There are about 300 species of bluegrass, which are common in the cold and temperate zones of both hemispheres, in the tropics they are found only in the mountains. Many perennial bluegrasses are valuable fodder plants. Bluegrass are common in habitats (ecotopes) of different ecological conditions. All of them are distinguished by the presence of free sheaths, when the lower part of the leaf, covering the stem, can be flattened, does not grow together with edges, spikelets collected in a paniculate inflorescence, 2-5 (up to 8)-flowered, at the base of the flowers there are winding hairs that are found when pulled out spikelet flower.

In relatively dry forests, often found on sandy soil bluegrass angustifolia, usually a large perennial, 40-80 cm tall, with a creeping rhizome, narrow leaves up to 1.2 mm wide, slightly spreading panicle with twigs rough from small spines.

On the edges, clearings and less dry meadows, a similar meadow bluegrass, with spreading inflorescence.

In various forests, among shrubs, it is not uncommon woodgrass bluegrass, with relatively small spikelets collected in a loose, often drooping panicle.

On damp and wet bottoms of ravines, ditches in broad-leaved and mixed forests occasionally found open bluegrass, characterized by articulated ascending stems, 50-140 cm tall, relatively wide leaf blades, 4-10 mm wide, and flattened, almost winged leaf sheaths.

In damp meadows, grassy swamps, along the banks of water bodies, in wet cuvettes, it is common marsh bluegrass, with gradually pointed leaf blades (in most bluegrass they are short pointed).

Along paths and roads, in disturbed places, wastelands, in weedy places, tufts of one-to-a-young annual bluegrass.

In open areas with bare ground, embankments, roadsides, perennial oblate bluegrass, having a creeping rhizome, a flattened stem 10-40 cm tall and a relatively small inflorescence.

Common in damp meadows, roadsides common bluegrass, with a shortened rhizome, a rounded stem 30-100 cm tall and a relatively large panicle.

Note that bluegrass is often included in mixtures of lawn grasses, especially when creating sports lawns.
