Seven kinds of grafting technology allows you to become a master of seedlings (1) Optimum temperature callus growth temperature is 20-25 ℃ (2) Interface humidity remained high humidity is conducive to the growth of callus. General use of plastic bags and wax seal ways of maintaining scion and rootstock humidity. (3) light rays callus significantly inhibited, in the dark callus will grow well, so after grafting to blackout. Usually with cultivated soil or opaque material package, create darkness. (4) the general quality of scion shoots good choice woody rootstock green seedlings distribution, do not choose to grow branches, due to the growth of branches easy dehydration. (5) scion rootstock and scion habits habits to be affordable, the survival rate is generally high germination rootstock, scion survival rate before germination is low, easy to dehydration death because scion to germinate. (6) during the grafting and grafting air temperature, soil temperature, scion of an active state is closely related Mou. When the anvil Germany are in a strong growth period, grafting a high survival rate. Therefore, according to the state flower seeds specially selected from quasi suitable grafting period. (7) the interface quality fast cutting speed and proficiency, cutting smooth interfaces. 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 of urban roads on the environmental pollution green seedlings to a certain 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 air pollution particles green seedlings for sale, and a representative of Highway Greening Species on Dust Catching simulated test wholesale green seedlings, screened out stagnant dust ability of the plant to improve the 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 in the Dust Catching street when plant leaves found 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.
