宁夏灌区盐碱地水稻丰产高效技术集成研究

Research on Technology Integration of High Yield and Efficiency of Saline-alkaline Rice Field in the Ningxia Irrigation Area

为了提高淡水资源的利用效率,同时有效防治土壤次生盐渍化,改善土壤结构,深入探究控灌节水抑盐、施用土壤调理剂等已经成为宁夏引黄灌区盐碱地可持续发展的迫切需要。为此,进行水稻品种、土壤调理剂、灌水量在盐碱地上集成研究。试验结果表明,选用富源4号品种,施用丹路菌剂,采用控灌的集成效益最佳。

In order to improve the utilization efficiency of freshwater resources and effectively prevent secondary soil salinization at the same time and improve soil structure, a thorough research of water-saving and salt-suppressing of control irrigation and application of soil conditioning agents has become an urgent need of sustainable development of saline-alkali soil in Ningxia Yellow River Irrigation. To this end, an integrated research of rice varieties, soil conditioner and irrigation in saline-alkali soil is conducted. The results show that the best integrated benefit is in the amendment of selecting Fuyuan 4th variety, applying Dan Road agent, and using control irrigation.
