What are the varieties of turfgrass? What are the types of turfgrass?

The varieties of turfgrass are:

1. Ryegrass: It grows fast and is mostly used as a common grass for golf courses.

2. Early maturing grass: good low temperature resistance, -9 is still green, and it is a cool-season turfgrass species.

3. Strand scissors: strong adaptability, good trampling resistance, and pruning resistance.

4. Knotweed: easy to reproduce, not easy to get sick and pests, long life, and good elasticity.

5. Dogtooth root: a warm-season turfgrass species, drought tolerant, and good regeneration.

6. Other varieties: tall fescue, velvet, Manila, Bermuda, etc.

General characteristics of turfgrass:

1. The growth point of the above-ground part is low and has tough leaves, so the mechanical damage during pruning is small, which is conducive to regeneration and can reduce the degree of trampling damage.

2. The leaf requirements are relatively small, the number of leaves is large, and the fine and dense leaves are the necessary conditions for the establishment of a carpet-like lawn.

3. Lawn plants are mostly clustered or creeping type, which is easy to form a relatively dense grass layer.

4. The number of branches per unit area is large, so it is easy to form a dense and wide-ranging high-quality lawn.

5. Lush growth, wide distribution, and strong regeneration ability, so even if the lawn is pruned many times, it is easy to be restored, promote the storage of branches, and promote dense growth.

6. Strong adaptability to the environment, good or bad climate and soil conditions and their changes, especially extremely harsh environmental conditions such as storms, heavy rains, dry mornings, etc.

The more common lawn species are:

Dogtooth root lawn (commonly known as Bermuda lawn or green back grass lawn), Manila lawn leaves are more pointy and pointy, river parks and many other places are planted, knotweed lawn leaves are relatively wide and salt-alkali resistant, high fescue lawn is also green lawn in winter, cut strand lawn field is used for the position of golf course tee, the lawn is evergreen in all seasons does not need to be mixed to achieve four seasons evergreen, the lawn ** is relatively high, Buddha grass lawn is often used for roof planting, and its drought and cold resistance, no special maintenance is easy to survive, It can also be used for garden plant planting collocation.

The main varieties are early maturing grass, tall fescue, evergreen, cool-season lawn, mixed lawn and so on.

Lawn refers to the grassland that is artificially planted or artificially maintained and managed, and plays the role of greening and beautification. It is one of the indicators of the degree of civilization of a country and a city. Refers to a ground cover covered with grasses and other plants with a slender texture and its roots and stolons filling the surface of the soil.

It is suitable for landscaping, landscaping, air purification, soil and water conservation, and providing outdoor activities and sports venues.

Construction Method: 1. Sow grass seeds directly. It is generally carried out in spring and autumn. This method is mostly used in cold-ground grasses.

2. Plant grass directly. It is generally carried out in spring and summer. This method is mostly used in northern China.

3. Propagation with stem segments. It is generally carried out in the summer or rainy season. This method is mostly used for warm floor lawns.

4. Pave the grass blocks directly. It can be done in all seasons in warm areas, and it is used in northern China to pave sports field lawns in summer and autumn.

At present, the method of direct seeding is widely used to build lawns. Grass seeds, viscose, and fertilizer mixtures can be sprayed on the rock slope to force grass planting by spraying the slurry sowing method, or the grass seeds can be pre-placed on the non-woven fabric to germinate, grow into a lawn planting belt, and then spread on the ground to form a lawn.

The advantages of the direct seeding method are: the amount of grass seeds is small, the distribution is uniform, the seedlings are neat, it can prevent the breeding of weeds, and it will not be washed away by water when planted on the slope, and it can form various patterns. In addition, grass blocks are produced in advance from seeds or stems and branches without soil or thin soil, or ribbons of grass are rolled into grass rolls, which can be used to lay the lawn at any time indoors and outdoors, and can be formed immediately after paving.

There are many types of turfgrass, different forms, and different uses, and we classify many turfgrasses according to certain criteria as the classification of turfgrass. This is usually based on economic taxa, with the help of laws such as plant taxonomy or adaptation to environmental conditions;

According to the phylogenetic taxonomy,Most turfgrasses belong to the family Poaceae, and only a small part is not a family, but this small part has many families and is very niche, so it is also called non-grasses. It belongs to about dozens of varieties such as the subfamily of early-maturing grass, the subfamily of millet and the subfamily of teff, the subfamily of fescue, the subfamily of ryegrass, the subfamily of knotweed, and the subfamily of shearheads.

According to geographical distributionTurfgrass can be divided into "warm ground type" and "cold ground type", and can be divided into "warm season type" and "cold season type" according to their ecological adaptability to temperature.

The essence of these two divisions is the same, but the emphasis is different. The optimum growing temperature of cool-season turfgrass is 15-24 degrees Celsius, and it is widely distributed in humid, semi-humid and semi-arid areas with cool climates. The distribution area of some species can extend into areas where the temperature and cold are excessive.

The optimum growing temperature of warm-season grasses is 26-32 degrees Celsius, and they are widely distributed in humid, semi-humid and semi-arid climates. Some warm-season turfgrasses are low, low-mowing tolerant, drought-tolerant, heat-tolerant, and trampling-resistant, but they are less cold-tolerant and tend to wither and fade at low temperatures. Since only a few species have access to seeds, warm-season turfgrasses are mainly built with nutrients.

In addition, warm-season turfgrass has a strong competitiveness and encroachment, and once the lawn community is formed, it is difficult for other grass species to invade. Therefore, warm-season turfgrass is mostly single-seeded, and mixed-seeded lawns are rare.

According to the width of the blades, it can be divided into broad-leaved grass and fine-leaved turfgrass.

The grass of the lawn is mostly and the family, perennial grass, and the varieties of the lawn mainly include Manila, small bran grass Taiwan grass, dogtooth root, early maturing grass, tall grass grass and rye grass and so on. Among them, Xiaokang grass has the characteristics of rapid diffusion, good turf performance, and trampling resistance. It can be used to build some high-quality lawns such as golf courses, hockey rinks, etc.

There is a lot of grass for the lawn. Wheat green, Danish grass, sheep's beard grass ...... aqui te amo。

Grass used for garden lawns includes, ryegrass, dogtooth root, carpet grass, tall fescue, etc.

There are many types of turfgrasses with different forms, and according to certain criteria, the classification of many turfgrasses is called the classification of turfgrass. This is usually based on economic taxa, with the help of laws such as plant taxonomy or adaptation to environmental conditions;

According to the phylogenetic classification of plants, most turfgrasses belong to the Poaceae family, which belong to the precocious grass subfamily, the millet subfamily, and the teff subfamily, with about dozens of species.

First, high fescue, high fescue is the most recommended variety of green lawn, its leaf color is very attractive, the color is translucent, the root system is very developed, the survival rate is almost as high as 100%, and the comfort of the leaf is very good, people are very comfortable, even if they fall on it will not hurt, just like a natural bumper bed, in our country has used it in a large number of sports fields and some green lawns, and it is also very cold-resistant, the use of green lawns in our country is the largest, It is very suitable for large-scale production as a green lawn.

Second, the dog's tooth root, its name is very funny, but it itself grows very neatly and neatly, so it does not need too much pruning, it can have a good shape, it generally adopts a creeping growth mode, and it grows very fast, trampling resistant, often used as the surface vegetation lawn of the sports field, and it is also a good plant to maintain the soil.

3. Green grass, green grass is a very advanced grass dogtooth root species, generally used in golf courses, its lawn looks very fine, the leaves are very short, but very tight, just like a carpet tailored for the lawn, and its growth rate is fast, drought and cold resistance, with high resistance to diseases and pests, can be planted in many different soils, and grows very well, very regular and orderly.

Fourth, the Manila lawn.

Manila lawn is also a common green lawn, which is drought-resistant, pruning-resistant, trampling-resistant, and cultivated as a perennial lawn plant, generally planted in garden scenic spots, courtyards, streets, and wetland parks. Manila lawn has so many advantages and of course many disadvantages, it is easy to turn yellow in colder temperatures and grows relatively slowly, which means that the ability to repair is relatively slow.

5. Bermuda Lawn.

Bermuda lawn is a knotweed, it is known for its strong rhizome, Bermuda lawn rhizome is very developed, so it is more tolerant to pests and diseases than other lawns, it is less difficult to maintain, and Bermuda lawn is also an economical and practical lawn.

1. Bermuda.

Bermuda is a perennial warm-season lawn variety of the genus Poaceae, which is heat-tolerant and drought-resistant, with low plants, strong stolons, and strong soil fixing ability, and is mainly used in sports grasslands, slope protection lawns and other occasions.

2. Manila.

Manila grass has a strong tillering ability, it is also drought tolerant, the root system is well developed, and most importantly, the coverage is also great. Manila grass plants are relatively low, good trampling resistance, suitable for sports grassland, and are also commonly used in stadiums, parks, and communities.

3. Paradise grass.

Paradise grass is a perennial herbaceous plant with strong viability and adaptability, this plant is very resistant to trampling, pruning, and dwarf, and belongs to the very popular warm-season lawn species.

4. Ryegrass.

Ryegrass grows fast, has good trampling resistance, is cheap, and is often used in slope protection greening, park greening, square greening lawn and other occasions, and its cold resistance is very good.

5. Tall fescue.

High fescue is a cold season variety in the north, it belongs to one of the excellent lawn varieties, cold and drought resistance, suitable for the construction of lawn or slope protection greening, so that the effect is fast, the effect is good.

Methods of maintenance of turfgrass.

1. Light. The maintenance of turfgrass requires light, and in hidden and shady areas, turf plants are prone to poor growth, and if the seedlings are uneven after sowing, the seeds will not fully mature after fruiting. If sufficient light is provided during maintenance, its leaves and roots will grow very well.

2. Ploughing. During the planting and maintenance of turfgrass, the land needs to be ploughed, and the depth is not less than 20cm, so that the root system can penetrate deep into the soil layer and increase the depth of ploughing.

3. Pruning. The mowing of turfgrass is necessary, regular pruning can maintain a good ornamental effect, maintain a certain growth height, increase tillering, promote the growth of transverse stolons and rhizomes, and increase the density of the lawn.

Commonly used greening grasses in the south:

The Yangtze River Basin, the area south of the Yangtze River, has a shorter winter and a relatively warm winter temperature as an answer, and these areas are on the contrary a warm season lawn with a long spring, summer and autumn, a warm climate all year round, and is suitable for the growth of heat-tolerant warm-season lawnsFor example, Manila, Bermuda, Dogtooth Root, Tianfudao, Taiwan Grass, American Sijiqing and other varietiesThe common denominator of this kind of grass is that it is resistant to high temperatures, does not dormant in summer, does not die in the sun, and does not wither, and the disadvantage is that it is not cold-tolerant.

Commonly used greening grasses in the north:

North of the Huai River, the central and western regions, the Yellow River Basin, the Northeast region, North China, and the Northwest region are an answer, which may also be what we often call the north, right? The north is mostly temperate oceanic monsoon climate, the influence of cold air in the north is long, and the four seasons are distinct, spring and autumn are short, winter is long, and summer is very hot.

The most commonly used varieties in the north are: early maturing grass, tall fescue, ryegrass, knotweed, and shearweedThese kinds occupy the vast majority of the northern lawn market, and some other small categories that are not in the flow are almost negligible.

On various landscaping construction sites, these lawns are the most commonly used, and naturally they are the most commonOther commonly used varieties are white clover seeds, red clover seeds, Bermuda seeds, etc., which are also varieties with better greening effect.
