| 摘要: |
| 目的 为了优化石菖蒲种子育苗关键技术，扩大石菖蒲优良种苗繁育，降低石菖蒲种植成本提供参考。方法 采用不同粗细的石英砂（0.1~0.2、0.2~0.4、0.4~1.0、1.0~2.0、2.0~3.0、3.0~5.0、5.0~8.0、8.0~12.0 mm）和泥炭1∶1（体积比）混合基质，在25℃恒温光照培养条件下对石菖蒲种子的萌发和幼苗生长发育的情况进行比较。结果 不同粗细的石英砂混合基质对石菖蒲种子发芽率和发芽势影响显著，其中石英砂粗细为0.2~0.4 mm的混合基质时其发芽率和发芽势最高，分别为88.89%±6.94%和78.89%±1.92%。不同粗细的石英砂混合基质对石菖蒲幼苗的株高、最大叶宽、最大叶长、根条数、最大根长的等生长指标影响显著，但对叶片数的影响不显著；在幼苗生长阶段使用纯泥炭基质培育的石菖蒲幼苗的生长发育各项指标均最佳。结论 不同粗细的石英砂和泥炭混合基质对石菖蒲种子的萌发和幼苗的生长发育有显著影响，在石菖蒲种子育苗实际生产过程中，综合考虑育苗的成本和效益，选用纯泥炭作为石菖蒲种子萌发和幼苗生长发育的基质是比较理想的材料。 |

| Abstract: |
| Objective To optimize the key techniques for seedling cultivation of Acorus tatarinowii Schott seeds, expand the propagation of high-quality seedlings, and reduce planting costs. Methods Quartz sand of different particle sizes (0.1~0.2, 0.2~0.4, 0.4~1.0, 1.0~2.0, 2.0~3.0, 3.0~5.0, 5.0~8.0, 8.0~12.0 mm) was mixed with peat in a 1:1 (v/v) ratio as the growth medium. The germination and seedling growth of Acorus tatarinowii Schott seeds were compared under constant temperature (25℃) and light cultivation conditions. Results The mixed substrate of quartz sand with different particle sizes had significant effects on the germination rate and germination potential of Acorus tatarinowii Schott seeds. Among them, the mixture wit 0.2-0.4 mm quartz sand showed the highest germination rate (88.89%±6.94%) and germination potential (78.89%±1.92%). The mixed matrix of quartz sand with varying grain sizes significantly affects growth indicators such as plant height, maximum leaf width, maximum leaf length, number of root branches, and maximum root length of the Acorus tatarinowii Schott seedlings, but has no significant effects on leanumber. During the seedling growth stage, Acorus tatarinowii Schott seedlings cultivated in pure peat substrate showed optimal performance across all growth and development indicators. Conclusion The mixed substrate of quartz sand and peat with different particle sizes has significant effects on the seed germination and seedling growth of Acorus tatarinowii Schott. Considering both cost and effectiveness in practical production, pure peat is an ideal substrate for seed germination and early seedling growth. |
