中文摘要:针对江苏沿海滩涂盐碱地,探究不同籼型杂交稻品种在盐碱地中钠钾离子的积累与产量的关系,并筛选出比较适合江苏盐碱土种植的品种。选取24个杂交籼稻品种,动态测定植株中钠钾离子吸收的变化和干物质质量变化,以及土壤中钠钾离子变化和可溶性盐的变化。结果表明,水稻种植显著降低了土壤中钠钾离子和可溶性总盐含量,其中钠钾离子含量分别降低7.67%和25.08%,可溶性总盐含量降低33.52%;并通过植株钠钾离子积累量和产量筛选出3个耐盐杂交籼稻品种(E10、E11和E12),其中钾离子积累量和产量最高的品种为E10(323.60 kg/hm2和10.78 t/hm),钠离子积累量最高的品种为E11(11.71 kg/hm2)。 |

Abstract:Aiming at the coastal saline-alkali land in Jiangsu, the relationship between the accumulation of sodium and potassium ions and the yield of different indica hybrid rice varieties in the saline-alkali soil was explored, and the varieties suitable for planting in the saline-alkali soil in Jiangsu were selected. Twenty-four hybrid indica rice varieties were selected, and the change of the absorption of sodium and potassium ions, dry matter weight in plants, sodium and potassium ions and soluble salts in the soil was dynamically measured. The results showed that rice planting significantly reduced the content of sodium and potassium ions and total soluble salt in the soil. The content of sodium and potassium ions was reduced by 7.67% and 25.08%, respectively, and the total soluble salt content was reduced by 33.52%; three salt-tolerant hybrid indica rice varieties (E10, E11 and E12) were screened out by their accumulation of sodium and potassium, and grain yields.The varieties with the highest potassium ion accumulation and yield were E10 (323.60 kg/hm2 and 10.78 t/hm), the variety E11 (11.71 kg/hm2) had the highest sodium ion accumulation. |
