河套灌区盐碱地不同甜菜品种离子吸收特性与耐盐性评价
Ion Absorption Characteristics and Saline-alkali Tolerance Evaluation of Different Sugar Beet Varieties in Hetao Irrigation District
摘要
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.关键词
