摘要: 【目的】分析盐碱胁迫对甜菜光合物质积累及产量的影响,研究盐碱胁迫对甜菜生长发育影响的过程,为甜菜抗盐碱栽培提供理论依据。【方法】采用室外盆栽方法,按照NaCl∶Na2SO4∶Na2CO3∶NaHCO3=1∶9∶1∶9比例配制成1 mol/L的混合盐碱溶液,各处理Na+浓度分别为0、0.5%、0.8%及1.0%,以甜菜品种HI0135、SD12830和MA11-8为材料,测定盐碱胁迫下甜菜的农艺性状、净光合速率(Pn)、生物量积累及产量。【结果】随着盐碱胁迫浓度的增加,HI0135的相关性状表现为先升高后下降,0~0.5%盐碱胁迫浓度对甜菜生长发育、光合物质生产及产量有促进作用;SD12830和MA11-8甜菜表现为持续抑制。【结论】HI0135甜菜品种在盐碱胁迫浓度为0.5%时表现出一定促进作用,对盐碱环境有较强的适应性。

Abstract: 【Objective】 To study the effects of salt-alkali stress on the accumulation and yield of photosynthetic matter in sugar beet and reveal their effects on its growth and development in the hope of providing theoretical basis for salt-alkali tolerance cultivation of sugar beet. 【Methods】An outdoor pot experiment was carried in this experiment, a mixed salt solution of 1 mol/L was prepared according to the proportion of NaCl: Na2SO4: Na2CO3: NaHCO3 =1∶9∶1∶9, The concentration of Na+ in each treatment was as follows: 0,0.5%,0.8% and 1.0%. Using sugar beet varieties HI0135, SD12830 and MA11-8, the agronomic traits, net photosynthetic rate (Pn), biomass accumulation and yield of sugar beet under saline alkali stress were measured.【Results】The results showed that HI0135 beet plant height, leaf number, Pn, biomass accumulation, salt sensitivity index, salt tolerance index and yield were increased first and then decreased with the increase of concentration of salt and alkali stress, the growth and development, the biomass accumulation and yield of sugar beet were promoted under the saline alkali stress of 0-0.5%, but SD12830 and MA11-8 beets showed persistent inhibition.【Conclusion】Under the conditions of this experiment, HI0135 beet varieties showed a certain promotion effect when the concentration of saline alkali stress was 0.5%, which indicated that it had strong adaptability to the saline alkali environment

Key words: sugar beet; saline alkali stress; agronomic traits; biomass accumulation; yield
