The effects of new vertical device on the morphlogy and quality was studied in Italian lettuce under the condi-tion of sand cultivation. The results showed that the new device can make the lettuce growth cycle shorted, yield im-proved. The lettuce cultivated in the new vertical device had better quality than CK in harvest time, such as the content of Vitamin C, soluble sugar and soluble protein, but less than CK in Nitrate of leaves. Its chlorophyll was not prominent than CK. The lettuce cultivated in new vertical device was more prominent at dry root and fresh root than CK. All above showed that the new vertical device can make plant grow better than CK by changing the environment around root.
