Study On Ecologic Adaptability Of Thymus Serpyllum L. Var.asiaticus And Its Application In Landscape

Thymus serpyllum L. var.asiaticus is a undershrub in Labiatae. Its characteristics are creeping growth ,Connecting green leaves,Fine textureUniformity can be formed naturally, there are ups and downs to the landscape group,Floret-intensive branches, Lawn rare plants with the "aromatic spend more" rare and valuable characteristics ,and adaptability, resistance are strong, and easy to cultivate, simple management, a wide range of uses, and has a good potential for development and application. It has important significance for the seeds of Thymus serpyllum L. var.asiaticus, ecological adaptation and the application of the garden on the rich Inner Mongolia landscaping plants and even the whole country.Through the seeds of Thymus serpyllum L. var.asiaticus, wild and cultivated species phenology observation, ecological adaptation (including shade-tolerant, resistant barren, cold tolerance, tolerance of abuses, drought tolerance), different habitats under the control of plant tissue microstructure research and in the garden of the allocation. By the following conclusions:1. Thymus serpyllum L. var.asiaticus seed germination rate and the appropriate germination temperature is 15℃to 25℃, and the high temperature above 30℃under the germination rate is low, it is necessary in a cool environment for planting Thymus serpyllum L. var.asiaticus general, the spring and fall would be more appropriate . Seed germination of Thymus serpyllum L. var.asiaticus for a broad temperature range, can be cultivated in the northern city of breeding to raise the city's natural, the native trees in urban richness. Thymus serpyllum L. var.asiaticus seed very small, but reduce soil germination rate, the seeds should be sown directly sow, in order to come into close contact with the soil to a pat hand, Fuchahoudu should not be more than 0.5 cm.2. Hohhot area under natural conditions, Thymus serpyllum L.var.asiaticus turn green in late March, April bud initiative, spent only five months early, 5 ~ June full bloom, 6 to September floret often embellished greenery between the stars. Some years 9 to October there is a full bloom. Beginning in late September turn into yellow. Green period from late March to late October, Thymus serpyllum L. var.asiaticus green longer period of up to 200 days. 3. Thymus serpyllum L. var.asiaticus strong adaptability to the environment, soil requirements lax. To base fertilizer application with no fertilizer, plant height, crown and the flowering date of differences little thyme in the light of the circumstances strong growth in the appropriate shade faster (45.36%) cases cheerfully good, 15×15cm Zhuhangju about 45 days when the cover up to 100% of bluegrass and turf compared to the drought of Thymus serpyllum L. var.asiaticus stronger. Community upper Thymus serpyllum L. var.asiaticus, severe pruning of plants after the sharp decline in only a portion of the residual stolon, great impact on their ability to restore growth; thyme injury suffered hypothermia obviously have to -30℃temperature, but as the temperature further reduced thyme suffered more serious injuries.4. Wild and cultivated soil physical properties of different media and nutrient conditions arising from the differences can not change the characteristics of the structure.5. Thymus serpyllum L. var.asiaticus can be used in large area of aromatic and ornamental turf, revetment lawn, planting flowers important reading glasses style flower beds, potted display.
