Abstract: Xanthium spinosum, a highly invasive plant known for its rapid reproduction and widespread dispersal, significantly impacts the production of food and forage crops. It leads to reduced crop yields, diminished quality, and pasture degradation, making its control crucial for agricultural production. In this study, we investigated the effects of six sand burial depths (1 cm, 2 cm, 3 cm, 5 cm, 7 cm, and 9 cm) on seed germination, seedling growth, and allometric relationships of X. spinosum. The aim was to explore the ecological control of X. spinosum and the crop sowing strategies. The results were as follows: The germination index and emergence rate in the 7 cm and 9 cm burial depth treatments were significantly lower than those in other treatment groups. The plant height, plant weight, number of thorns, and thorn length were all significantly lower than those in the treatments with burial depths of 1 cm and 2 cm. (P<0.05). The root-to-shoot ratio in the 7 cm and 9 cm burial depth treatments was significantly higher than that in other treatment groups (P<0.05). The allometric exponent of stem dry weight in the 3 cm burial depth was significantly lower than those in the 5 cm, 7 cm, and 9 cm treatment groups (P<0.05). Overall, deeper sand burial inhibited the seed germination and seedling growth of X. spinosum. Therefore, this study laid a theoretical foundation for the scientific prevention and control of X. spinosum and crop sowing. It is advisable to conduct deep plowing before crop sowing.

摘要: 刺苍耳(Xanthium spinosum)作为一种快速繁殖、广泛扩散的恶性入侵植物,严重影响了农作物的生产,导致农作物减产,品质下降,牧场退化。本研究通过设置1 cm,2 cm,3 cm,5 cm,7 cm和9 cm共6个沙埋深度处理,分析了刺苍耳种子萌发、幼苗生长和异速生长关系,旨在探究刺苍耳的生态防控及作物播种策略。结果显示:在7 cm和9 cm埋深处理下的发芽指数和出苗率显著低于其他处理组,株高,株重,刺数量和刺长均显著低于1 cm和2 cm埋深处理。7 cm和9cm埋深处理的根冠比显著高于其他处理组。茎干重的异速生长指数在3 cm埋深下显著低于5 cm,7 cm和9 cm处理组。综上所述,过深沙埋抑制了刺苍耳种子萌发和幼苗生长,建议在作物播种前进行深耕作为其防控措施,本研究为刺苍耳的科学防控和作物播种奠定了理论基础。
