| 中文摘要: |
| 为研究NPK肥料组合处理对沙地中科羊草根系形态特征的影响，试验设15种不同的NPK肥料组合配比，测定不同肥料处理下中科羊草的根系形态指标。研究得出：根系生物总量在N5P8K8处理下显著最高；根系总根长在N8P5K2处理下显著最高；根系总体积在N11P3K3处理下显著最高；N5P3K3处理下中科羊草的根系总表面积、平均根直径、根茎干重均显著最高。因而，N5P3K3肥料组合处理下中科羊草的根系形态特征综合最优。 |

| To explore the effects of NPK fertilizer combinations on the root characteristics of Leymus chinensis in sandy soil, root morphological indices were measured under 15 different NPK fertilizer treatments. The results showed that root biomass was highest under the N5P8K8 treatment, while total root length was greatest under N8P5K2 The total root volume was highest under N11P3K3 In addition, the total root surface area, average root diameter, and rhizome dry weight of Leymus chinensis under the N5P3K3 treatment were significantly higher than those under other treatments. Overall, the root morphological characteristics of Leymus chinensis are most favorable under the N5P3K3 fertilizer combination. |
