| 摘 要： | 根据测土配方施肥“3414”方案中的部分处理传统施肥(CK)、N0P0K0、MN2P0K2、MN2P1K2、MN2P2K2、MN2P3K2、MN2P2K0、MN2P2K1、MN2P2K3、MN0P0K0]，在山东寿光日光温室内进行了番茄磷钾肥肥效研究。结果表明：整个生长季中番茄产量MN2P1K2处理区最高，达到160.86 t·hm-2，比传统施肥方式增产7.2%。土壤肥力水平较高，磷肥的利用率最高仅为22.6%，钾肥最高仅为23.7%，与其他处理相比较，施磷肥过多有明显减产趋势，只需施适量有机肥和少量磷肥即可达到理想产量；施钾肥在前期效果不是很明显，故前期应少施，中后期要适当多施，以促进番茄对钾肥的吸收

| 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. |
