| 摘 要： | 上海郊区水田土壤,可以古岗为界分成东西两部分:浦东的沙泥、夹沙泥、黄泥头以及岗身的沟干泥是由长江沉积物发育起来的草甸土,地势较高(吴淞0.4米以上),地下水位较低(地面1米以下),质地偏中(轻壤-重壤),土壤通气孔隙较多,渗透性较好,因此土壤比较爽水,生产性能好,产量较高;浦西的青紫泥是由古太湖和其他许多湖荡港叉葑淤成陆的沼泽土,地势低洼(地面高程在吴淞零上2.2-3.5米),地下水位高(地面以下0.3-0.8米),质地偏粘(中壤-重壤),土壤通气孔隙少,毛管孔隙多,吸持力强,土壤透水性差,易于囊水,根系环境不良.

| Abstract: | The present paper. deals with mainly the drainage problem of the soils in the suburbs of Shanghai. The soils are mostly used under a rotation system of wheat (hull-less barley)-rice annually. Excess content of soil moisture usually restricts the growth and yield of winter crops. Various ameliorative measures for the improvement of drainage condition of soils are described. |
