| 摘 要： | 安徽霍邱县城西湖农场,是1966年围湖造田建成的一座大型机械化农场.该场地势低湿,土壤粘重,种植作物以旱作三麦为主.场內建有完整的排灌渠系,日降雨100毫米所形成的地面迳流可在一昼夜之内排除.但因土壤内排水性能甚差,田块又大,根层内饱和水长久不得消失,因而造成土壤湿害,既影响作物正常生长,又给田间机械化作业造成许多困.

| Abstract: | Cheng-si-hu Farm At Huochiou County in Anhwei Province is located in a lowland with soils clayey,heavy and moist in nature.The crops (mainly wheat,barley or naked barley) in this area are injured seriomly by waterlogging due to the illdrainage of the soil in rainy season.This condition has been greatly improved by means of the wide application of the mole channel drainage.The experiment in a disastrous rainfall of approximately 100 mm per day showed that the drainage of mole channel laid in an interval of 10m,60-70cm in depth and combined with surface drainage of shallow ditches in an interval of 50-100 m could resist the concentrated rainfall of moderate intensity. |
