- 摘要:
- 以美国杂交种F1代万寿菊为试材，研究了0、22.5、45.0、67.5、90.0、112.5 kg/hm2 6种钾肥水平对万寿菊生物学性状及产量的影响。结果表明：随着钾肥施用量的增加，万寿菊开花期提前，株高、茎粗、株冠直径、分枝数目、单株干重和叶黄素含量都呈现先升后降的趋势；在K2纯钾施用量22.5 kg/hm2处理下，鲜花产量和叶黄素产量达到最高。在该试验条件下，寒地万寿菊种植合理的施钾量为K2O 22.5 kg/hm2，鲜花产量最高，可达26.39 t/hm2。
- Abstract:
- Taking United States of American F1 hybrids of Tagetese recta as test materials, the effects of 0, 22.5, 45.0, 67.5, 90.0, 112.5 kg/hm2 6 potash levels of potassium fertilizer on biological characteristics and yield of Tagetese recta were studied. The results showed that by increasing amount of potash fertilizer, flowering early, height, stem diameter, strains of crown diameter, number of branches, dry weight per plant and chlorophyll lutein and yield were most, significant difference among treatments. In condition of this experiment, the reasonable amount of potash fertilizer to Tagetese recta in cold region was 22.5 kg/hm2, which could make flower yield reach to the most 26.39 t/hm2.
