采用盆栽試驗方法，以黃華占為對照，探討鹽脅迫對海稻86植株生長和礦質元素吸收、運輸及分配的影響。結果顯示：鹽脅迫抑制了水稻干物質量的積累，海稻86與黃華占耐鹽閾值分別為8.72、6.35 g/kg，與黃華占相比，海稻86表現出較強的耐鹽能力。鹽脅迫下，與黃華占相比，海稻86通過根系選擇性吸收Na+，調節Na+在各器官水平的分配，其葉鞘能積累更多Na+，可減少Na+對葉片的毒害。鹽脅迫下，黃華占葉片中K+含量與對照無顯著變化，但其葉鞘及根系中K+含量在土壤全鹽含量為4.64 g/kg條件下，其K+含量大幅降低，降幅分別達53.8%和70.0%；海稻86各器官中K+含量隨鹽脅迫程度增加而逐漸下降，葉片中K+含量降幅相對較低。隨著鹽脅迫程度加深，黃華占葉鞘中Ca2+、Mg2+含量顯著下降，而海稻86無顯著變化；此外，與黃華占相比，海稻86具有較強抑制Na+，促進Ca2+、Mg2+向上運輸的能力。
The pot experiment was used to study the effects of salt stress on growth of Oceanrice 86 and absorption,transportation and distribution of mineral elements using Huanghuazhan as control. The results showed that salt stress inhibited the dry matter accumulation of rice plants. The salt tolerance threshold of Oceanrice 86 and Huanghuazhan was 8.72 g/kg and 6.35 g/kg,repectively. Compared with Huanghuazhan,salt tolerance of Oceanrice 86 was stronger. Under salt stress,Oceanrice 86 selectively absorbed Na + through the root system and regulated the distribution of Na+ at the organ level. Its leaf sheath accumulated more Na +,reducing the toxicity of Na+ to the leaves. The content of K + in Huanghuazhan leaves did not change significantly from that of the control,but the K + content in the leaf sheath and root system was 4.64 g/kg in the soil. The K+ content was greatly reduced by 53.8% and 70.0%,respectively. The K+ content in various organs of Oceanrice 86 gradually decreased with the increase of the degree of salt stress,and the decrease of K+ content in leaves was relatively low. The content of Ca2+ and Mg2+ in the leaf sheath of Huanghuazhan decreased significantly with the increase of saltstress,while Oceanrice 86 had no significant changes. Compared with Huanghuazhan,Oceanrice 86 had a strong ability to inhibit Na + and promote the upward transport of Ca2 + and Mg2 +.
