再生水灌溉对冬小麦生长生理特性及产量的试验研究

Test and Study on Growing Physiologic Property and Yield of Winter Wheat Irrigated by Recycled Water

根据再生水灌溉冬小麦的试验研究,分析了再生水灌溉对冬小麦的生长生理特性及产量的影响,提出了在大量使用再生水灌溉的同时,必须加强对农田氮素动态变化过程的监测,并据此适量调整减小施肥数量,避免农田氮素过量而导致对水体的污染。

According to test and study of winter wheat irrigated by recycled water,the paper analyzes the influence of recycled water to irrigate winter wheat on its growing physiologic property and yield,presents that monitoring dynamic change process of nitrogen element in farmland must be strengthened,when a lot of volume of recycled water is used,and on the basis of monitored result,winter wheat＇s fertilization quatity must be regulated and decreased adequately,so as to avoid polluting water body duo to overdose of nitrogen element in farmland.
