营养因子对燕麦生长及K+、Na+含量的耐盐性调控研究
Regulation of Salt Tolerance of Nutritional Factor on Growth and K + and Na + Content of Oat
摘要
Abstract
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.关键词
