摘要:

探究不同甜菜品种在内蒙古河套灌区盐碱地中的离子吸收特性及耐盐性差异,为耐盐甜菜品种筛选与盐碱地利用提供理论依据。以甜菜品种‘KWS1197’‘KWS9899’‘H7IM15’‘KUHN4092’‘SV1752’为材料,在内蒙古河套灌区典型盐碱地开展田间试验,系统测定其产量、含糖率、生物量、光合参数及植株体内K+、Na+等阳离子浓度与累积量。结果表明,‘KWS1197’在盐碱胁迫下表现最优,其产量(80102.03 kg/hm2)、产糖量(14122.35 kg/hm2)显著高于其他品种,较最低值品种‘KWS9899’分别提升16.99%、27.14%。其块根生物量占比达82.1%,净光合速率(Pn)、蒸腾速率(Tr)及叶片SPAD值均显著高于其他品种(P<0.05)。离子吸收特性表明,‘KWS1197’表现出拒钠保钾能力,其块根Na+浓度在生育末期显著低于‘KUHN4092’,而块根K+累积量(465.97 g/株)显著高于‘KWS9899’。研究认为,甜菜耐盐性与离子选择性吸收能力、光合效能稳定性及生物量向块根的高效分配密切相关,‘KWS1197’是适宜在河套灌区盐碱地种植的耐盐碱优势品种。

Abstract:

The purpose of this study is to investigate the ion absorption characteristics and saline-alkali tolerance differences of different sugar beet varieties in the saline-alkali soil of the Hetao Irrigation District, aiming to provide a theoretical basis for selecting salt-tolerant varieties and utilizing saline-alkali land. Using sugar beet varieties ‘KWS1197’, ‘KWS9899’, ‘H7IM15’, ‘KUHN4092’, and ‘SV1752’ as test materials, a field experiment was conducted in typical saline-alkali soil of the Hetao Irrigation District in Inner Mongolia. Yield, sugar content, biomass, photosynthetic parameters, and the concentration and accumulation of cations such as K+ and Na+ in plant tissues were systematically measured. The results showed that ‘KWS1197’ performed best under saline-alkali stress. Its yield (80102.03 kg/hm2) and sugar yield (14122.35 kg/hm2) were significantly higher than those of other varieties, which were 16.99% and 27.14% higher than the lowest-performing variety ‘KWS9899’. The proportion of its root biomass reached 82.1%, and its net photosynthetic rate (Pn), transpiration rate (Tr), and leaf SPAD value were significantly higher than those of other varieties (P<0.05). Ion absorption analysis indicated that ‘KWS1197’ exhibited a capability for sodium exclusion and potassium retention. The Na+ concentration in its roots at the end of the growth period was significantly lower than that in ‘KUHN4092’, while the K+ accumulation in its roots (465.97 g/plant) was significantly higher than that in ‘KWS9899’. In summary, the saline-alkali tolerance of sugar beet is closely related to selective ion absorption, stability of photosynthetic efficiency, and efficient biomass allocation to the roots. ‘KWS1197’ is a superior variety suitable for cultivation in the saline-alkali soil of the Hetao Irrigation District.

Key words: saline-alkali tolerance, sugar beet, variety, cation, ion absorption characteristics
