Field experiment was conducted in greenhouse to investigate how the basal application different ratios of slow release fertilizer with reduction irrigation influenced tomato yield，quality，nitrogen used efficiency as well as soil NO-3N contents.The results showed that there was no significant difference in yield and tomato quality between routine and reduction 30% irrigation，but reduced NO-3-N leaching from 8.0% to 63.7% in 40~60 cm soil layer.Tomato yield increased 19.4%~22.1%，21.5%~22.6%，14.5%~15.3% by basal application 30%，50% coated urea and 30% biocharbased nitrogen fertilizer，respectively.And nitrogen used efficiency increased 10.1%~12.4%，10.2%~12.7%，2.3%~4.0%，respectively.Two species of slow release fertilizer decreased tomato fruit nitrate content by 6.3%~14.4%，3.0%~7.9%，12.4%~13.3% compared to urea routine application，but increased lycopene content and sugaracid ratio，improved the quality of tomato.Basal application 30% and 50% coated urea and 30% biocharbased nitrogen fertilizer with reduction 30% irrigation significant reduced nitrogen leaching in soil，NO-3-N content in 40~60 cm soil layer reduced 28.7%，20.0%,75.0%，respectively.Therefore，in greenhouse tomato planting，30%~50% of nitrogen fertilizer used slow release released fertilizer and reduction 30% irrigation，could obtain the tomato high yield，reduce nitrogen leaching，improve fertilizer use efficiency and agriculture water saving.
