Cool-season grass species Poa 35 yuan per catty, catty seeds about 100 to 1,420,000 per acre is about 0.5 to 0.75 kg seeding. Bluegrass seed requires planting fine soil preparation, fertilization, irrigation, before sowing repression, weed control, shallow trenching, shallow overburden. In the Qinghai-Tibet Plateau, the general spring, autumn also. Price occasional change with the market, please contact us at the pro-shot baby, in order to maintain your maximum discount! Kentucky bluegrass are perennial herbs, fibrous root system, with rhizomes, leaves attractive, green and long, good viewing. Suitable for cold weather, high humidity areas growth, strong resistance to cold, drought tolerance somewhat less resistant to trampling. Rhizome breed rapidly, renewable power, resistance to cutting. In the northern and central regions, the south part of the cold regions are widely used in parks, offices, schools, residential areas, playgrounds and other places green. Kentucky bluegrass is native to Eurasia, in the Asia region, widely distributed in the northern temperate cold and humid regions. In China located in northeast China, Hebei, Shandong, Shanxi, Inner Mongolia, Gansu, Xinjiang, Qinghai, Tibet, Sichuan, Jiangxi and other provinces (regions), natural distribution in cold and wet habitats, often become constructive species of mountain meadow, or for Other associated species meadow steppe communities. China gradually cultivated promotion in the world, Asia and the European part of the Soviet Union are distributed. European countries and more cultivated. In North America, Canada and the northern United States is the wet areas to adapt to a good pasture, and cultivated a large area. In the United States, known as Kentucky bluegrass, the name of the cultivated varieties, the country has cultivated near the northern average 15 ℃ isotherm adaptation of the best varieties. Also use a wide range of high quality northern temperate cool season turfgrass. This cool-season grasses in China in recent years, but the limelight, many people know it's name, because in Beijing's Tiananmen Square, including the front door watchtower sides and stuff Chang'an Avenue, almost all kinds are lawn with Kentucky bluegrass The different varieties of grasses. This grass is perennial, with creeping rhizomes fine. Its characteristics are like the cold and humid climate, in Beijing and other regions, can remain green longer period to meet the requirements of the so-called evergreen certain extent. But not suited for high temperatures and drought conditions, especially in hot and humid conditions under Beijing, susceptible to disease, so the higher management requirements, require a higher investment. Many commercial varieties, and often there are new varieties appear. Americas, Dawn, excellent, midnight, etc. are common varieties of Kentucky bluegrass. Morphological characteristics: perennial herb, with creeping rhizomes fine; root whisker. Stem erect, sparsely plexiform or solitary, smooth, cylindrical, up to 60 to 100 cm, with sections 2-3, the upper section between 11 to 19 centimeters long. Ligule membranous, truncate; length of 1 to 2 mm. Leaf stripe, apex acuminate, smooth, flat, the volume of 6 to 18 cm long, 3 to 4 mm wide. Sheaths rough, loose, with longitudinal stripes, longer blades. Panicles oval, or tower, to carry out, apex slightly drooping, long 13 ~ 22 cm, width of 2 to 4 cm. Ecological features: Kentucky bluegrass is a perennial grasses longevity, suitable for growing in cold and wet climates, under irrigated cultivation conditions in cold semi-arid and arid environment, you can also grow well. In the absence of moisture and warm hot habitats, new branches and stem growth should go restricted, that a few weeks after the end of the hot climate, growth and can recover form the grass. Kentucky bluegrass on climate adaptation, roughly when the temperature 5 ℃, can begin to grow; at 15 ~ 32 ℃, it can grow sufficiently higher or lower temperatures can reduce plant growth rate, but the soil moisture supply situation can occur significant role. When the temperature is maintained at above 15 ℃, can promote the development of roots and stems go, extreme cold and heat have caused damage, especially not resist high temperature drying. In full sunlight conditions, can grow well when soil moisture and nutrients as well, under the mild shade, can grow normally. Soil adapt relatively wide range, suitable for neutral to slightly acidic soil, but the ability of saline-alkali soil pH7.0 ~ 8.7. The most suitable fertile, well-drained soil structure and, but also the ability of barren soil, calcareous soil in a significant response. Forage Value: Kentucky bluegrass is important to put cattle pasture. From early spring to autumn, grazing feed intake often young plants, nutrient-rich, horses, cattle, sheep, donkeys, mules, rabbits are hi feed. The horse is the most eating grass and a sound value. Before seed milk stage, horses, cattle, sheep eating; mature late, the lower stem becomes stiff, reduced palatability, the upper stems and leaves, cattle, sheep still eating.夏秋青 grass on a yak, Tibetan sheep, goats fatten grass, winter is long fat grass horse hay for livestock forage excellent complement. For poultry and pig feed, but also have good feeding value. Lush leaf growth, leaves not falling, but also for hay, but the mature leaf stalks of grass, hay, digestibility decreases. Leaves and inflorescence proportion of the total weight of the whole plant accounted for about 34.82%. Bluegrass strong resistance to grazing, grazing can use from spring to autumn, able to maintain the growth and yield of plants, the impact is not very significant. But the proper light grazing, rotational grazing or row delay and can maintain the normal growth of plants.
