Abstract: The effect of vanillin and P hydroxybenzoic acid on Chinese fir (Cunninghamia lanceolata) woodland soil and Schima superba woodland soil was studied in pot culture experiment.The results showed that contents of nitrogen,potassium and organic matter were lower than the control and their change scope were 21.8%,2.8% and 8.2% respectively.The content of available phosphorus were higher and the change scope was 23.7%.In addition,both changes became more significant with increase of phenolic concentration.These results showed that allelochemicals released by plant may affect content of nutrition in soil,and give rise to nutrition deficiency,and then affect Chinese fir growth.

Key words: Nitraria roborowskii, salinity stress, MDA content, antioxidative enzyme system, osmotic regulation.
