Under the conditions of uniform nutrient fluid and centralization of management， the optimum matrix suitable for the lettuce growth in solid soilless culture on the vertical column was screened out through determining and analyzing the physiochemical performance of different matrixes and the growth performance and quality of lettuce. ［Result］ B1 group including grass peat， sheep manure， vermiculite， furnace ash and slag with the mixture ratio of 3∶3∶2∶1 was better than other groups on the moisture retention，pH， rate of emergence， leaf characters， lettuce plant height and chlorophyll content. ［Conclusion］The matrix of B1 group was the optimum matrix suitable for the lettuce growth in solid soilless culture on the vertical column.
