| Abstract: |
| 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 avidii). 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. |
