中文摘要	为研究盐碱地燕麦高产栽培中的营养配比,利用生物方法提高土地利用率、改善生态环境。采用防雨棚土培方法,进行了氮、磷、钙营养元素不同配比对燕麦耐盐性的研究,结果表明:营养因子氮、磷、钙剂不同调控处理能够促进燕麦植株的生长发育,减弱盐胁迫对细胞质膜的损伤,不同程度增加燕麦植株体内K+含量、减少Na+含量,增加K~+/Na~+值,可提高燕麦产量。燕麦耐盐性最优营养调控组合是高氮(2.00 g/盆)低磷(0.65 g/盆)加钙(10 g/盆)处理,在各处理中,燕麦表现出较强的耐盐性,增大K~+/Na~+值和可提高产量。
英文摘要	The bioavailability of saline soil is an effective measure to improve the land utilization and improve the ecological environment.Oat has extensive adaptability in arid,semi-arid areas with highly vulnerable environment;it is the characteristics and green health crop in Inner Mongolia and has good effect improving saline soil.The study of different ratio of nitrogen,phosphorus and calcium on the salt tolerance of oat was conducted with a method of soil culture in flowerpot in a rainproof shed.The main research results showed that through the study of grown,plasma lemma and K~+,Na~+content of oat,different adjustable treatments of nitrogen,phosphorus,calcium could promote the oat plant growth and development,reduce the injury of salt stress on plasma membrane,increase the K+content,decrease Na+content in various degree and increase K~+/Na~+in oat,and increase oat yield.The optimal combination of nutrition and regulation of salt tolerance of oat was high nitrogen(2.00 g/pot),low phosphorus(0.65 g/pot) and added calcium(10 g/pot)(T5).The oat showed strong salt tolerance,high K~+/Na~+value and yield in all treatments.The research has practical application value for the nutrition ratio in high yielding cultivation of oat on saline and alkaline land.
