| 摘 要： | 滴头流量、灌水量及埋深与土壤湿润体的关系是涌泉根灌设计的依据。通过室内土槽试验,研究了涌泉根灌的滴头流量、灌水量及滴头埋深对均质粘壤土湿润体变化的影响。结果表明：涌泉根灌土壤入渗湿润体在垂直向下距离和水平扩散距离均与灌水时间成幂函数关系,相关系数达到0.98以上;滴头流量和灌水器埋深对土壤入渗湿润体影响较大,而灌水量对...

| Abstract: | The relationship between the wetted body and the discharge of emitter,the volume of water,and the depth of the emitter is the base of bubbled root irrigation design.The influences of different discharge,volume of irrigation water and the depth on the wetted body of clay loam are gotten though some experiments on lab in this paper.The results shows that the remarkable power functions exist between horizontal and vertical wetting fronts and the infiltration time,and the correlation coefficient are above 0.98.... |
