Abstract：The field experiment with '3414' design (CK,N0P0K0,MN2P0K2,MN2P1K2,MN2P2K2,MN2P3K2,MN2P2K0,MN2P2K1,MN2P2K3 and MN0P0K0) was conducted in Shandong Shouguang in order to investigate the effect of P and K fertilizer on facility tomato. The results showed that the treatment of MN2P1K2 got the maximum yield, which was 160.86 t·hm-2, 7.2% higher than the traditional treatment. In addition, P application on tomato had no effect or even decreased yield with high soil available phosphorus level. Appropriate organic manure with decreased phosphorus supply was an effective method to increase tomato yield.The effect of potash fertilizer was not remarkable in early growing period, so potash fertilizer should be supplied less in this period and later more in the mid-late growing period.
