贵州生态退化区域稻田节水控制灌溉试验研究

摘要

2009 -2010 Rice irrigation experiment have been taken in ecological degradation area in Bijie city ot Guizhou province, national support project researchers, and local researchers and farmers all participated in it. Three kinds of irrigation have been compared, including water-saving irrigation, conventional irrigation and wetting irrigation. The result shows that the wetting irrigation is the optimization irrigation method which has promoted high- er yield, saved more water and had higher water utilization, it can be used as a water-saving irrigation-oriented model to popularize in karst ecological degradation fragile area.%2009～2010年国家科技支撑和省长基金项目研究人员和毕节市有关研究人员、当地农户三结合，在喀斯特高原生态退化脆弱地区石桥小流域进行水稻的节水灌溉、常规灌溉、湿润灌溉3种方式的灌溉研究，分析比较，得出节水灌溉的优化灌溉模式，即：湿润灌溉模式产量最高，节水大、水分生产率最大，水分生产效益最高，为生态退化脆弱区域的农业节水得出灌溉导向模式。
