Abstract: Trials were conducted in laboratory and field in Beijing region indicated allelopathy of wheat straw on maize. Four phenolic acids as allelochemicals have been identified and quantified in no-tillage with wheat straw mulch. They are ferulic acid ( FA), vanillic acid ( VA), cinnamonic acid ( CA) and p-hydroxyben- zoic acid ( p-HBA). Their average amounts are ( 1. 31-2. 47) × 10-7, ( 2. 86-3. 77) × 10-7, ( 1. 53-2. 69) × 10-7and ( 1. 97-2. 60) × 10-7mol/ L, respectively, and they reduced slowly in soil. FA, VA and p-HBA were tested in laborotary bioassay for their allelopathic effects on germination and seedling growth of maize. The con- centrations required to reduce growth by 10% of maize radicle of FA, VA and p-HBA, namely ED10, are 1. 14, 3. 57, 6. 30 mmol/ L, respectively.
