Abstract Impact of different dripping emitters on tomato（Lycopersicon esculentum Mill.）growth，yield and water consumption in solar greenhouse was studied with the control of tension- meters．The results showed that the plant height of tomato increased significantly in Netafim drippers during fruiting stage．The tomato yield by Netafim drippers was also ranked the highest，with 9.3%，11.9%，14.3% higher than the treatment of Trace irrigation system，Beijinglvyuan and Baodinghuayu，respectively．The water consumption by Netafim drippers in the whole tomato growth stage was ranked the highest，with 4.0，8.3，4.9 mm increase than the treatment of Trace irrigation system，Beijinglvyuan and Baodinghuayu，respectively．Collecting all factors，Netafim drippers was suitable for use in planting tomato in solar greenhouse under gravity drip irrigation．
