| 摘 要： | 小麦拔节孕穗期受渍造成小麦严重减产，而排水则显著提高籽粒产量，有利于麦株吸收土壤中的氮、磷、钾矿质营养，对改善小麦籽粒的品质亦有较大作用。发展农田暗管排水降低地下水位对南方多雨地区小麦增产及改善品质有重大作用。

| Abstract: | Waterlogging that occurs in jointing and booting stages leads to significant reduction of winter wheat yield whereas sufficient drainage increases grain yield,facilitates absorbtion of N, P,K nutrients by plants and improves grain quality. Therefore,subsurface drainage in winter wheat field which lowers groud water table is of great importance to yield increase and guality improvement for areas of plenty rainfall in southern parts of China. |
