Abstract: Observation and studies show that shading significantly reduces the tiller formation, plant height and shoot weight of vetiver. After shading removed,the plants perform better, but not so well in plant heigat and shoot weight as those not been shaded.Fertilization promotes the height growth and tiller formation,and stopping it will result in a decrease of plant growth.In order to increase tillers,the plant should be cut twice annually,but excessive cutting is unfavourable.

Key words: altitude, soil microbial biomass, soil microbial community structure, PLFA, Dongling Mountain.
