为探讨科尔沁沙地菊芋物质积累速率和物质分配规律,通过对科尔沁沙地白皮和红皮菊芋各器官生物产量的动态监测,以期为菊芋开发利用提供依据。结果表明:白皮菊芋茎叶比呈先升高后降低的变化趋势,红皮菊芋茎叶比逐渐升高,整个生育时期红皮菊芋茎叶比均高于白皮菊芋,而根冠比白皮菊芋大于红皮;相同取样时间下,两品种菊芋叶比重、花比重和块茎比重之间均没有显著差异;物质在不同器官中积累速率并不相同,其中块茎在9月份出现后呈先升高后降低的变化趋势;除器官花外,两品种菊芋相同器官中物质分配速率也有显著差异。
In order to investigate the material accumulation rate and material distribution of Artemisia selengensis in Horqin sandy land, dynamic monitoring of the biological production of white and red Artemisia artemisiifolia plants in Horqin sandy land was carried out in order to provide the basis for the development and utilization of Artichoke. The results showed that the ratio of stem and leaf of Artemisia lanceolata rose first and then decreased, the ratio of stem to leaf of Artragahilum roseum increased gradually, and the ratio of stem and leaf of Jerusalem Artemisia latifolia was higher than that of Artemisia alopecuroides in the whole growth period, Anthurium was greater than the red skin; the same sampling time, the two varieties of Jerusalem artichoke leaves specific gravity, flower weight and tuber weight were not significantly different between the rate of material accumulation in different organs are not the same, including tubers in the first appeared after the rise in September High and low after the change trend; In addition to organ flowers, two varieties of Jerusalem artichoke in the same organ distribution rates were also significantly different.
