Abstract The effect of seven mixing peanut chaff substrate treatments on tomato seedlings was studied in the paper.The results showed that the substrate’s composition of peanut chaff∶cattle manure∶slag= 6 V∶2 V∶2 V was an appropriate match.The 6 indexes of this treatment as:stem diameter，plant height，stem and leaf fresh weight，stem and leaf dry weight，root dry weight and strong seedling index were higher than that of the other 6 treatments and were significantly higher than that of the control(peat∶vermiculite=2 V ∶1 V).The leaf chlorophyll content was not significantly different with that of the control.
