Study of Plant filtration Urban Road Green on the road greening of air pollutants on the dust filtration and adsorption having a barrier for the purification of air pollution have different degrees. Wu Hong Quan Urban Road Greening in the configuration of the plant noted that the unique nature of the plant may reduce automobile exhaust, noise and dust pollution on city roads on the environment to some extent, to achieve clean air goals. Wang Hui also that the use of green plants Dust Catching has become the most effective way to alleviate the particle contamination of the atmosphere, and a representative of Highway Greening Species on Dust Catching simulated test, screened out Dust Catching ability of plants for improve road traffic environment provides a theoretical basis. Feng Jianjun and other environmental benefits in Guangzhou road greening different cropping patterns were analyzed, the impact on the sidewalk after the adoption of the air pollutants in motor vehicle lane by green belt barrier purification, as well as in the green belt was not affected in case of a barrier purification comparative analysis to find out the effect of air pollutants barrier best model. Wang Zanhong found ginkgo seedlings base in the streets when the Dust Catching study of plant leaves, Euonymus strong Dust - Retention is an important mechanism of urban environment, clear surface layer of particulate pollution, its surface is 10μm or less stagnant dust particles. Wang et al. Also on forest highway barrier of heavy metals were studied, research shows that the road on both sides of the plant organs Pb content with increasing distance from the road is gradually reduced, the width of the belt for some heavy metal pollution has reduced vehicle significant role. Management points 1 outdoor winter flowers, tree trunks painted white painted white can eliminate overwintering pests of nursery stock base name trunks and bark crevices and branches to prevent sunburn. The proportion of white-agent formulation is: 36 to 40 parts of water, 10 to 20 parts of lime, 1 to 2 parts of salt, 2 parts of clay, 2 parts of calcium polysulfide liquid. First mix lime and salt dissolve, then pour lime sulfur and clay nursery stock base price, then white-Stir, white-in amounts not flow down shall prevail. 2, manual removal pest moth larvae often to hang on the branches within the cocoon winter, winter leaf litter, which can be manual removal seedlings base, concentrated fire. Enhanced cold will be planting seedlings, planting new seedlings and non-hardy garden plants, cold conservation is particularly important. Cold strengthening measures to prevent frost flowers, garden seedlings to improve the survival rate, survival and quality of tree growth next year is very important. Nursery stock base price, Hua Hin seedlings base (certified), seedling bases provided by the Chongqing Hua Hin green seedlings base. Chongqing Hua Hin green seedlings base (www.cqxhlh.com) is Bishan County, flowers, fruit seedlings leaders, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs . Hua Hin seedling bases in leadership with the staff warmly welcome all inquiries negotiations to create Hua Hin seedling bases better future.
