摘要
大田旱作条件下,研究了氮磷钾不同施肥配比对兰州百合产量、品质和养分吸收的影响。结果表明,PK和NK处理比对照CK增产3.2%和7.0%,NP处理比对照CK减产2.6%,化肥种类对兰州百合产量的影响顺序为钾肥>氮肥>磷肥。NPK处理较对照CK增产36.1%(P<0.05)。兰州百合为喜钾作物,适量施用钾肥可以提高其产量、总糖和粗淀粉含量。
Under dry-farming condition ,a field experiment was conducted to study the effects of different N ,P and K fertilization ratio on yield ,quality and nutrient accumulation of Lanzhou lily （ Lilium davidii ） .The results showed that the yield of lily under the treatments of PK and NK was increased by 3 .2% and 7 .0% ,respectively ,while that under the treatment of NP was reduced by 2 .6% ,compared with control .The effect of different fertilizers on yield of lily was ordered as K〉N〉P .The yield under the treatment of NPK was 36 .1% （ P〈0 .05 ） higher than the control .Lanzhou lily is a hipotassium crop ,and an adequate application of potassium fertilizer can increase its output ,total sugar content and crude starch content .
