Because of the slope is the product of the construction activities, the soil structure is destroyed completely natural on the slope. On the slope excavation, removal process, many slopes formed rock subsoil profile or cross-section, generally about soil organic matter content of only 0.2%, less than 20% moisture content, rarely found in soil microbial activities. Accumulation of debris rolling down the slope is formed, although no topsoil, compaction, including stones and more, but the organic matter content of up to 1.0% up to 25% moisture content, often the remnants of soil microbial activity, the slope common seed germination and root growth. 1.3 Slope natural resilience of our plant slope Wu secondary road from the south slope of fixed-point observation that: under the slope, rain soil seed starting root initiation, six months up to 30% slope vegetation cover, population mostly annual grasses, patchy distribution, species at the foot of the slope more moist, cover degree. The rock slope on the slope, six months appears only moss plant growth and crevice corrosion barren herbs such as Arthraxon. Slope of the mud layer 6 months only dry grasses grow and Dicranopteris Kei, Eastern Torike fern, but also the emergence Embelia-rooted and Masson pine seedlings, but coverage is less than 10%, are located in the lower part of the slope. Thus, the highway Slopes natural resilience is very low. 2 Slope Greening of plant material selection green plant material selection principle 2.1 (1) local native plant material screening based election lead foreign material, supplemented by excellent construction material breeding convenient, adaptable; (2) the selection of materials to herbaceous plants, vines, shrubs, giving seed to the source material diversity of local conditions configured with different combinations of methods; (3) the screening, evaluation materials Drought resistant barren as the main indicator, traits, growth characteristics as a secondary index, square to ensure the suitability of selected materials; (4) Select the type mainly propagated by seed, vegetative propagation species, supplemented for this stage of mechanized construction, reducing manual operations. Seed in the region to carry out roads, railways, dams and slope to collapse hillock plant survey, selected by observing better adaptability of species and collecting primary materials: 2.2 slope greening material selection method of step (1) primaries or kinds of bars. (2) check: Wu secondary road in the south, selected nine different slope conditions primaries sow test species by survival rate, saving rate, the growth performance of observation, evaluation and screening check species. (3) The runoff election: in highway slope, by a check residential green construction materials, observation, evaluation of the effect of construction, determine the type of application and promotion, and multiply selected material. Introduction of foreign material should also be checked, the final selection sow test, screened for good performance before construction. Results 2.3 slope greening material selected seven years, we have been selected plant material can be used for slope greening 18 species, of which 7 species of grass: dog shoots root or stem segments sow sowing; centipedegrass (seeding; bis Spike paspalum sowing; Stenotaphrum Ramet Manila grass seeding or planting stem section sow; Hance sowing or sow stem section; Bahiagrass planting white clover sown; shrub three kinds: Mountains soybean planting, Hu branches sowing; sow ways and means 3 3.1 shrub and grass slope greening Hunzai style selection tephrosia or shrub seedlings and herbaceous Le Chai Stenotaphrum or Reineckia, press 1 to 4 lines of herbaceous shrub row configuration, laterally open horizontal groove planting. This arrangement can overcome the initial single shrub impoundment Runoff, reduce erosion shortcomings of poor, can make up the difference between a single grass slope capability drawbacks to this configuration applies Slope 3.2 Soil Sacks planted on the slope and expansive soil type selection degradable films made diameter 10cm, with a network marks Soil Sacks, bags bottom place decomposition of organic base fertilizer, seed mix nutrition soil sandy, the bag 15 to 17 after bagging by 30cm × 30cm spacing implants Health Bags, bags half exposed slopes, half buried in the soil, then with stakes nails. This approach applies to the slope portion slopes and rock outcrops geometry within the framework of the slope more than 3.3 hybrid grass seeding formula selection 2 1-3 herbaceous seeds and fertilizer, organic fiber, water emulsions, water-formulated as seeding material into the T90 hydraulic spray planting machine, covered with a non-woven fabric after seeding. In this way fast grass germination, grass the coating is fast, less consumption of seeds and labor, on the stony slope less suitable land uses. slope uneven or thin soil slope, after mixing clay with straw bedding segment, but also seeding. 3.4 blocks spread grass planting ceremony in artificial turf or wild grass, dig 25cm × 25cm size, 3cm ~ 3.5cm thick turf blocks for planting material. After the slope smooth water, the slope will be wet the grass block plant shop, after pressing Puwan then spray water once a day, once a moisturizing spray within two weeks. This way of doing more consumption, high cost, but the green quick, suitable slope and slope down low on the slope use. If the steep slope on the slope adopt, after laying grass planting each block should be added a fixed peg.
