Abstract:: Hydro-seeding technology is introduced from abroad for rapid revegetation of side slope and is used mostly in southern China. But in Loess Plateau it’s not so effective. For this reason, microenvironment improvements and other measures were conducted which include different seedbed treatment, cover measures, combination of plant selection and aspects effect of slope. Results show, water retain for level steps is 1.75 times of that of non-treatment, while the original seedlings’ survival is 82.5% higher than the latter. Seedlings’ survival under the cover of light shelter and non-woven-cloth was 43% and 52% of the amount or the cover of straw. Vegetation coverage under straw was 5%～23.7% higher than that under non-woven-cloth. Coverage for combination of Caragan korshinskili and extraneous grass species and that of Nitraria tangutica and rural grass species at the end of growth period in the first year averaged 59% and 56.5%, while 52.5% and 77.5% for the second year. Studies show the reasons limits establishment of hydroseeding vegetation includes: soil particles for roadside slope was prone to loss, hydroseeding material was susceptible eroded, drought and high salt and alkali for soil. Micro-environment improvements, selection of rural shrubs and rural grass species can successfully establish hydroseeding vegetation, and ensure its long effect.
