水稻抗旱性节水性鉴定方法研究
Evaluation Method for Drought Resistance and Water Saving of Rice
摘要
Abstract
[Objective] To research the evaluation method for drought resistance and water saving of rice.[Method] Five irrigation treatments were designed,which were 100％ (0 kpa maximum water irrigation,CK),90％,80％,70％ and 60％.Tbe yield,plant height and root length were used to evaluate the water conservation and drought resistance of rice.[Result] Under the condition of gradually decrease of water supply,the plant height reduced but root length enhanced.Yield analysis and agronomic characters analysis showed that H518 and Hanyou 73 (CK) had the almost the same performance,indicating that H518 was water saving and drought resistance.[Conclusion] This method was simple,rapid and reliable,and provided theoretical basis for the water saving and dry farming technology of rice.关键词
