%X A pot experiment was carried out to study the effect of 3-methyl-phenol on the productivity and root/canopy ratio in wheat-faba bean intercropping and mono-cropping at concentrations of 0 (A0),150×10-6 mol/kg (A1), 300×10-6 mol/kg (A2) and 450×10-6mol/kg (A 3).Results show that in the maturity stage, yield of intercropped wheat improves by 59.26%,25.16 %,-44.33% and -74.15% compared to mono-cropping treatments of A0,A1,A2 and A3 respectively.Yield of intercropped faba bean improves by -8.79%,5.52%,13.40% and 160.38% respectively.In intercropping system,compensation for different components is an important function of yield stability.3-methyl-phenol shows greater positive economic benefit and yield harvest index under intercropping than under mono-cropping system at A1 dose,but as the dosage improves to A2 and A3,3-methyl-phenol shows less negative economic effect and yield harvest under intercropping than under mono-cropping system.Root/canopy ratio of wheat and faba bean intercropping decreases at 3-methyl-phenol dose of A1 and A3.Compared with mono-cropping system,intercropping shows an advantage of transferring photosynthesis to above-ground biomass.
