Selection of drought-resistance plants was studied by means of pot and field test in order to solve greening plants of slope and central green belt in Langzhuo highway in this paper, and clay aggregate mulch how to affect soil temperature, soil water content and plant photosynthesis was analyzed. So this paper would provide a theoretical reference for appropriate plants and mulching technique in Langzhou highway. The main conclusions were as follows:
(1)For five candidate plants of central green belt, E...
