1.
Based on the experimental data from Guilin Irrigation Experiment Station in Guangxi Autonomous Region,the relation of rainfall utilization and surface runoff in paddy fields under different rainfall frequency and different irrigation regimes is studied;i.
对广西桂林不同降雨频率与不同灌溉方式下的降雨利用、径流量分析研究表明,晚稻降雨利用率远高于早稻;早稻在"薄、浅、湿、晒"、间歇灌溉、传统灌溉模式下降雨利用率随降雨频率的增加呈缓慢上升趋势,而晚稻节水灌溉模式下呈上凸趋势;早稻全生育期和晚稻分蘖期、拔节期径流量很大,对肥料流失产生不利影响。
