园林绿化常见树木（The garden afforesting common trees） 园林绿化常见树木(The garden afforesting common trees) The garden afforesting common trees 1. White clover (see figure 2-1) White clover is also known as white clover, white trifoliate, Dutch warped, double cotyledonous perennial herb, with a life expectancy of more than 10 years. The white trifolium is native to Europe and Asia minor Asia region, currently China heilongjiang, xinjiang, yunnan, guizhou region all have wild resource discovery. It likes light and warm and humid climate, can also be able to endure the semi-shade, the drought, the humidity. The heat resistance is a little bit worse Strong ability. The soil is not strict, as long as the drainage is good, all kinds of soil can grow, and very much like the soil of calcium and humus. The ability to be resistant to fineness, acid and salt tolerance is poor. The main use of the white leaves is to build the ground. The seeding amount is sown 7.5 ~ 9 g/m2, and the drill is 3 ~ 6g/m2. The seedlings grow slowly and fear drought. In the microsaline soil, it is advisable to sow seeds with rhizobium to increase the root growth, or to transfer the soil in 1:4 proportion. White clover except grazing land cultivation, garden green space is usually a solid soil slope protection, the ground cover plants, flower terraces ornamental lawn etc, also can make single extensive lawn planting, can spread on the lawn have been completed, to increase the adaptability of the lawn. 2. White moss grass (see figure 2-2) White moss grass alias small sheep beard grass. Bai Ying moss grass like a cold climate, cold resistant ability is stronger, smoothly under a 25 ? in winter, not heat-resisting, poor summer growth, higher than 36 ? stop growing, and the complex phenomenon of dry. Resistance to poor, drought resistance. Since the grass has no creeping branches, the coverage is poor and can not be trampled. White moss is distributed in northern and northern latitudes in northern China. Common in liao Ningxia, hebei, shandong, henan and northwest of the slopes, rivers and vacant lots. Beijing to The green period is 240-250 days. The seeds and vegetative propagation methods were used to seed the seeds The seeds need to be processed, the seeds can be rinsed with water, and then they are spread out to dry. Sows 7-10 g/m. Vegetative propagation can be used to spread grass and plant roots. Because the growth is slow and the coverage is poor, it must be irrigated, whether seeded or vegetative. Frequently weeding. It is generally advisable to cut grass height by 3 to 4 cm. The grass is negative and strong, leaf green, slender, the appearance is neat and beautiful, is very good sparse forest Amusement lawn plants, many of which are used as ornamental and ornamental lawns in northern China Green materials such as parks, courtyards, streets, flower beds, etc. 3. Flat panicle (see figure 2 -- 3) The blade of an ice grass is also known as wild wheat and ice grass. Ice grass is a typical xerophyte. It is strong in cold and drought resistance and is a thick texture Rough, uncreeping, clumped grass. It is commonly used in cold and cold areas It is also known as the fairway ice grass, which does not irrigate the lawn and golf course. High grass clippings The degree is 4 ~ 8cm, the fertilizer should be less, irrigation should be controlled, too much water will inhibit Its growth. 4. Grass early grass (see figure 2-4) The grass is a cool and humid climate, with a strong cold tolerance, in northern China A 27 ? cold areas are safe overwintering. But drought resistance is poor, in arid areas Proper irrigation can also result in good growth. But in the heat of summer, even irrigation, still Poor growth. The soil with good drainage and loose texture is especially rich in humus soil. Growth is more common in soils with more limestone. In poor soil, growth is worse Red crest grass or Canada's precocious grass. The grass is precocious and wet, but it is wet In many places, its growth is not as good as the red grass or the common precocious grass. It's also less negative Red fox or common precocious grass. Grass precocious grass is the first place in the foreign lawn application, widely used in each Like green Spaces. Most of the precocious grass imported from abroad in China is the early grass of the meadow Growing in the north is one of the best lawn grasses. The method of sowing is generally established Lawn, also can be planted with plant planting method jianping. Some varieties sprout and plateau speed Soon, others are very slow, choosing grass should be chosen according to the specific situation. Grass precocious grass can be planted single planting, before sowing, should flat surface, seeding to want Mix well, cover the soil and water the water. Sowing capacity is generally 5-10 g/m, or In order to increase the growth of grass grass, such as perennial ryegrass, creeping purple fescue, and prostrum, etc Lawn resistance. In good soil conditions, the form can be expanded rapidly through the underground stem To form a dense, dense turf. The height of the trim is 2-4 cm. It will be temporary in time of drought or heat Dormancy, because of the underground stem, can resist the adverse climate to some extent, Once conditions improve, the grass can be restored. Some of the more heat-resistant and drought-resistant in nanjing in China The varieties such as vabbas can be used to make the summer and most other products in humid soil It is only possible to have a moderate shade under the right shade, otherwise the wilting rate is up to 75%. The grass is moist, fat and hot, the least hardy of the warm season grass. Resistant to trampling, negative resistance and poor resistance, best suited for moist, well-drained sandy soil. Drought tolerance and drought must be irrigated. The grass is in southern China, and in early march, it has faded in late December, with a green period of more than 280 days. In the early years of guangzhou, the cob was introduced from abroad, and it is widely used in guangdong, yunnan, sichuan and other places. Although it is vigorous, it needs to be properly maintained and fertilized. When height reaches 5 cm, should be pruned, otherwise will form grass, cause leaf infection disease. If can achieve fine maintenance, strengthen water management, in kunming, guangzhou and other places can reach the four seasons evergreen. Dull leaf grass is mainly used for forest rest lawn, but also can be used as the shade of the forest. As an extremely tolerant species, the application prospect is wide. 7. Perennial rye grass (see figure 2-7) Perennial ryegrass, also known as fata rye grass. Perennial ryegrass has a cool and humid climate, which is suitable for planting in cool summer and not too cold winter areas. 10 'C can be grown well, and below C is suitable for growth Above 35 'C growth is not good. Light is strong, Sunshine is short, Low temperature is good for tiller, The temperature is too high to stop or die midway. Rye grass is cold and heat resistant. In extremely cold or extremely hot spots, many years of black Wheatgrass becomes a short straw, usually only Can live for a few years. In northeast China, Inner Mongolia Areas cannot be overwintered or overwintered and unstable Southern summer temperatures often die. Black wheat grass can grow in annual rainfall of 500-1 500 mm, and it is suitable for about 1 000mm. Ability to be wet, but poor drainage or ground water is not conducive to growth. Drought and drought are more detrimental to the growth of rye grass. The soil requirements are strict and the soil is poor and barren. It is most suitable for the cultivation of good, fertile and moist clay loam, which can tolerate acid and alkali, and the appropriate pH value of soil is 6-7. Perennial rye grass is strong, but it is not resistant to low shear. The shade is slightly worse than the sun. The shade is prone to disease, and selection of disease-resistant varieties should be chosen. Perennial rye grass is native to southern Europe, north Africa and southwest Asia. It has been cultivated in Europe for 400 years and has been widely cultivated in the United States, Australia, Japan and New Zealand. China used to introduce forage, and has selected a variety of forage grass. There are a lot of grass varieties in north China. Perennial rye grass often USES sowing. Sowing capacity is 15-30 g/m, which can be increased to 50g/m if necessary. Rye grass sprouts quickly, usually from five to seven days after the broadcast. Because of its tiller strength and rapid growth, it must be pruned regularly, control its height, and promote base tiller, so that it can quickly reach the plateau. To keep the rye grass green, nitrogen should be applied regularly. In parks, courtyards and small green fields, perennial ryegrass is often used as a pioneer plant to quickly form much-needed lawns. Still can sprout grass mixed seeding of slow, such as Kentucky bluegrass, before the Kentucky bluegrass emergence, flat bed protection from the harm of soil and water erosion, in order to increase the resistance of the lawn and especially when not placing mulch or slope planting, this feature is more useful. However, it should be noted that the rye grass should not exceed 20%, otherwise, the expanded black straw can encroach on the entire ping bed, making it difficult for the precocious grass to root and survive. Because of lolium perenne trampling resistance capability is strong, can be used as a playground lawn planting material, also can be used for repairing damaged lawn grass seed, use its rapid germination and growth ability, timely fill alopecia areata. It can also be used on warm season lawns such as the dog's root, and multicast at the end of autumn to make up for and keep the green of the winter lawn. 8. Gao yangmao (see figure 2-8) Tall fescue is also known as reed fescue, fasik, etc. With a wide range of ecological ranges and a wide range of ecological range, high fescue is suitable for moist climate and fertile soil. It can also grow well under high water level. More hardy and can continue to grow in 1 ? temperature, temperature is higher than 4 ?, the growth speed. It is also suitable for hot spots, the most heat-resistant varieties of the cold season grasses. While tall fescue is considered cold season Lawn grass, but it's vulnerable to low temperature, In colder regions of the temperate zone, when exposed to low temperatures, they tend to die out in only a few years, becoming the short-lived perennial grasses. Therefore, in cold and high altitude area, generally not adopted. In the transition zone and southern temperate zone, it is a longer life. It is not strict to the soil, and can grow in the soil with water and poor drainage, and can adapt to acidic and alkaline soil, and has certain salt tolerance. It is strong, strong and trampled, often used in sports fields or areas with high traffic. But since it lacks the ability to spread its roots, the recovery is poor and is not the ideal playground grass. The grassland is produced in Europe, and the humid regions of xinjiang and central northeastern China are also wild. Grass grass, but it is vulnerable to low temperature, in temperate regions, when exposed to low temperature, it is often only a few years to die, becoming a short-lived perennial grass. Therefore, in cold and high altitude area, generally not adopted. In the transition zone and southern temperate zone, it is a long life. It can grow in the soil, which is not strict to the soil, and can grow in the soil of the water and the poor drainage, and can adapt to the acidic and alkaline soil, and have certain salt tolerance. Tall fescue blade is tough, strong and trampled, often used in sports fields or areas with large human traffic. But since it lacks the ability to spread its roots, the recovery is poor and is not the ideal playground grass. The grassland is produced in Europe, and the humid regions of xinjiang and central northeastern China are also wild. The horse's hoofs are warm and humid, and the ability to shade is very strong. The soil is not strict, but in the fertile place, flourish. Lack of fattening leaves and yellow and green, the coverage decreases. It can withstand certain low temperature, the cultivation in eastern China, the color fade in the coldest time in winter, the upper part of the grass layer becomes brown, but it can still be safely wintering. Can be safe summer, basically evergreen. Horseshoe is also able to withstand drought, not to be trampled and should be planted in a small area. Horseshoe is widely used in the south, Europe and New Zealand to view lawns and traffic safety lawns. It was introduced and planted in guangzhou in 1980, and it can be adapted to the south of the Yangtze river basin. Horseshoe gold is poor in damp and solid soil, and needs to be irrigated regularly and fertilized properly. When pruning to 1.3-2.5 cm, the blade becomes smaller and the cover is large. When trimming to 3.8 to 5cm, the blade is large and the cover is small. China is used for small flower beds, flower-diameter and mountain stone gardens, for ornamental lawn cultivation, and also for the layout of garden green Spaces and small event sites. 15. Creeping benton (see figure 2-15) The creeping benton is also known as the benton, which is also known as the benton, the prostrate, and the prostrate, the grass. It is a perennial herb, with cold and humid climate, widely distributed in warm areas of the world, and growing in China. The crawl shears are beautiful, resilient, low and low to 5mm. When the lawn is damaged, the prostron can quickly cover the ground, a feature that compensates for its shortcomings. This grass is hardy and mild. Good salt tolerance, but poor growth in solid soil. The prostrate benton can be used to reproduce, separate it from the sod, and divide the prostrum into segments or sections, and then transplant it to a ratio of 1:7 (usually a stem truncated to 7 segments). However, the sowing method is usually used to build the flat. The sowing capacity is 3 ~ 5 g/m2, which can be increased to 7 g/m. Because the seed is very small, the flat surface should be whole Flat and thin, quality requires more than grass grass. When used as a golf course, the soil should be mixed with sand to reduce soil compactness. A mechanical perforation ventilation is required to reduce the compactness of the soil. Need to be pruned often, the height is 5-13 mm, the main use is a drum mower, the condition allows can every day once. The dry season requires frequent or daily irrigation. When the temperature is high, the water can be squirted slightly at noon. Creeping bentgrass is the most need careful maintenance type cold season grass varieties, because of its shallow root system, often need to management, is generally not as the courtyard lawn, fruit collar and neutral zone is mainly used for golf course, tennis court, bowling green and the grass is also sometimes used in golf course fairway and high quality turf. 16. Double ear finches (see figure 2-16) The double ear finches refer to the root of the water and the perennial herb. China is produced in the middle and lower reaches of south China, yunnan and the Yangtze river. Warm and moist, often born in the ditch, near the pool, or other low-wet areas, can also grow in more dry areas and spread widely. It also has a creeping stalk, which spreads quickly and keeps the soil and soil, and is a good preservation plant. The grass is moist, fat and hot, the least hardy of the warm season grass. Resistant to trampling, negative resistance and poor resistance, best suited for moist, well-drained sandy soil. Drought tolerance and drought must be irrigated. The grass is in southern China, and in early march, it has faded in late December, with a green period of more than 280 days. In the early years of guangzhou, the cob was introduced from abroad, and it is widely used in guangdong, yunnan, sichuan and other places. Although it is vigorous, it needs to be properly maintained and fertilized. When height reaches 5 cm, should be pruned, otherwise will form grass, cause leaf infection disease. If can achieve fine maintenance, strengthen water management, in kunming, guangzhou and other places can reach the four seasons evergreen. Dull leaf grass is mainly used for forest rest lawn, but also can be used as the shade of the forest. As an extremely tolerant species, the application prospect is wide. 7. Perennial rye grass (see figure 2-7) Perennial ryegrass, also known as fata rye grass. Perennial ryegrass has a cool and humid climate, which is suitable for planting in cool summer and not too cold winter areas. About 10 'C can grow better, 27 ? for growth under appropriate temperature Above 35 'C growth is not good. Light is strong, Short sunshine and low temperature are beneficial to tiller. The temperature is too high to stop or die midway. Rye grass is cold and heat resistant. In extremely cold or extremely hot spots, many years of black Wheatgrass becomes a short straw, usually only Can live for a few years. In northeast China, Inner Mongolia Areas cannot be overwintered or overwintered and unstable Southern summer temperatures often die. Rye grass can grow in annual rainfall of 500-1 500 mm About 1 000mm is appropriate. Ability to be wet, but poor drainage or ground water is not Conducive to growth. Drought and drought are more detrimental to the growth of rye grass. Compare the soil requirements Strict, the happiness is not poor, it is best to be planted in a good, fertile and moist soil The appropriate soil pH value is 6-7. A perennial rye Grass resistance is strong, but it is not resistant to low shear, and the average green space stubble is 4-6cm. Resistance to The shade is slightly worse, and it grows in the sunshine. The shade is prone to diseases, and the selection of varieties should be noted Select disease-resistant varieties. Perennial rye grass is native to southern Europe, north Africa and southwest Asia. It's already in Europe 400 years of cultural history, in the United States, Australia, Japan, New Zealand and other countries To a wide range of plants. China used to introduce forage, and has chosen to produce a variety of herbage products Kind of. The low - grass type rye grass varieties are used in the northern Chinese cities More. Perennial rye grass often USES sowing. Sowing capacity is 15-30 g/m, for example Special needs can be increased to 50g/m. Rye grass sprouted quickly, usually after sowing Five to seven days out. Due to its tiller strength and rapid growth, it must be regularly pruned and controlled Its high growth, the promotion of base tiller, so that its rapid coverage of formation. To keep the rye grass covered Green should be applied regularly. In parks, courtyards and small green fields, perennial ryegrass is a pioneer Species to quickly form a much-needed lawn. It can also be planted with the grass seed of early mature grass Mixed seeding, before the early crops, protect the bed from soil erosion, to increase The resistance of the lawn, especially when the mulch or slope is not placed, is more As useful. But pay attention to the rye grass cannot exceed 20%, otherwise the expansion ability is strong black Wheatgrass will encroach on all the beds, making it difficult for the grass to survive. The ground, dry and wet, can grow. Because of the roots spread and strong tillering force, can be long To be evacuated and dense grass. Spring grows early and can continue to grow until autumn. Purple sheep maoxi cool humid climate, temperature 4 "C, seeds begin to sprout, 20 ~ 25 ? for the optimum temperature for growth, 30 ? when wilting, 38 ~ 40 ? plants wither. Don't Heat resistant, resistant to poor and acidic soil, growing well in sandy soil. Purple fescue grows slowly, usually without spreading ability, with the growth of the ground part, The coverage gradually increased. Moderate resistance, moderate resilience, strong negative resistance, Grass for the best shade of grass in cold season.
