摘　　要：通过田间小区试验,利用不同处理阶段的养殖废水灌溉冬小麦,测试了小麦二个生育期的光合特征指标和产量。结果表明:不同厌氧水灌溉量的冬小麦叶片光合特征和产量呈现厌中>厌高>厌低的趋势;混水灌溉的叶片光合特征和产量呈现厌清1∶5>塘清1∶5>对照>原清1∶5>清水。建议避免应用过量的(灌水定额≥830m3/hm2)厌氧水直接灌溉冬小麦,较适宜灌溉的混水为厌清1∶5和塘清1∶5的混水比例。Different treatment stages of swine wastewater were used for wheat irrigation by the field experiment method. And the two growing periods of photosynthetic characteristics and yields were monitored. The results showed： Photosynthetic characteristics and yields of wheat with different amounts of anaerobic wastewater irrigation decreased in the order M〉H〉L. Photosynthetic characteristics and yields of wheat with mixed wastewater irrigation decreased in the order Tan〉Tec〉CK〉Tor〉Tgw. The study suggested not to directly use excessive anaerobic wastewater （Irrigating Quota≥ 830 m^3/hm^2） to irrigate wheat, and the appropriate mixed waters for irrigation was Tan and Tec.
