Rodent activity is an important factor that affects the growth and development of . Studying the effect of rodent disturbance on plant ecological stoichiometric ratios helps evaluate the mechanism by which rodent disturbance affects plant growth and development. In this study, , a dominant plant, and the gerbil, a typical rodent in the Gurbantunggut Desert, were selected as research objects. By measuring the biomass, root soil , and C: N: P ecostoichiometric ratios of the assimilated branches of at different growth phases, the impact of great gerbil disturbance on the biomass, ecostoichiometric ratios, and nutrient uptake and use of were investigated at different growth stages. The results showed that the gerbil disturbance increased the biomass of the aboveground part of the adult . Gerbil disturbance also increased the soil N/P around the roots during the growth stage and the assimilation branch when the plants were middle-aged. In addition, this disturbance decreased the C/N value. The photosynthetic nitrogen use efficiency (PNUE) and photosynthetic phosphorus use efficiency (PPUE) of during various growth periods decreased, and the absorption of total nitrogen (TN) in the soil decreased. However, soil total potassium (TK) absorption increased. The soil TN absorption capacity was weakened by gerbil disturbance. Meanwhile, the TK absorption capacity was enhanced, and the biomass of adult increased. PNUE and PPUE of were decreased by gerbil interference. In this study, the influence of gerbil disturbance on nutrient absorption by and use of was determined. This has provided a baseline for further studies on the coexistence mechanisms of gerbils and
啮齿动物活动是影响[植物名称]生长发育的一个重要因素。研究啮齿动物干扰对植物生态化学计量比的影响，有助于评估啮齿动物干扰影响植物生长发育的机制。在本研究中，选取[植物名称]（一种优势植物）和长爪沙鼠（古尔班通古特沙漠中的一种典型啮齿动物）作为研究对象。通过测定不同生长阶段[植物名称]同化枝的生物量、根际土壤以及碳：氮：磷生态化学计量比，研究了长爪沙鼠干扰对[植物名称]不同生长阶段生物量、生态化学计量比以及养分吸收和利用的影响。结果表明，长爪沙鼠干扰增加了成年[植物名称]地上部分的生物量。长爪沙鼠干扰还增加了生长阶段根系周围以及植物中年期同化枝的土壤氮/磷比。此外，这种干扰降低了碳/氮值。[植物名称]在各个生长时期的光合氮利用效率（PNUE）和光合磷利用效率（PPUE）均下降，土壤中全氮（TN）的吸收量减少。然而，土壤全钾（TK）吸收量增加。长爪沙鼠干扰削弱了土壤全氮吸收能力。与此同时，全钾吸收能力增强，成年[植物名称]生物量增加。长爪沙鼠干扰降低了[植物名称]的PNUE和PPUE。在本研究中，确定了长爪沙鼠干扰对[植物名称]养分吸收和利用的影响。这为进一步研究长爪沙鼠与[植物名称]的共存机制提供了基线。
