摘要
优化冬小麦-夏玉米品种周年匹配,明确冬小麦季适宜灌水量,是进一步提高冬小麦-夏玉米周年产量及水分利用效率的重要途径。本试验以小麦品种泰科麦30(耐旱型)、济麦22(高肥水型)和黄淮海区主推玉米品种登海605、郑单958为供试材料,系统研究冬小麦-夏玉米品种匹配及灌水量对周年产量及水分利用效率的影响。结果表明,泰科麦30+登海605组合W1(冬小麦越冬水、返青水、拔节水、开花水和夏玉米蒙头水各60 mm)处理周年干物质重增加显著,W2处理获得最优周年产量,但与W1差异不显著,W0处理周年耗水量少、周年水分利用效率高;泰科麦30+郑单958组合W1(冬小麦拔节水、开花水和夏玉米蒙头水各60 mm)处理的周年产量最高,周年水分利用效率最优。济麦22+登海605、济麦22+郑单958组合均在W2处理下干物质积累显著,周年产量最高。济麦22+登海605组合周年耗水量W0显著低于灌水处理,进而周年水分利用效率最佳;济麦22+郑单958组合W1处理有最佳周年水分利用效率。结论:综合产量和水分利用效率,泰科麦30+郑单958为最优冬小麦-夏玉米品种组合,W1为最佳灌水量。
It is an important way to further improve the annual yield and water use efficiency of winter wheat and summer maize by optimizing the annual variety matching and determining the appropriate irrigation amount in winter wheat season.In this study,the effects of winter wheat-summer maize variety matching and irrigation amount on annual yield and water use efficiency were systematically studied using wheat varieties Taikemai 30(drought-tolerant type)and Jimai 22(high fertilizer and water)and maize varieties Denghai 605 and Zhengdan 958 mainly popularized in Huanghe-Huaihe-Haihe district as test materials.The results showed that the annual dry matter weight of the combination of Taikemai 30 and Denghai 605 increased significantly under W1 treatment(60 mm of overwintering water,returning green water,jointing water and flowering water of winter wheat and Mongolian water of summer corn respectively)and the optimal annual yield was abtained under W2 treatment,which was not significantly different with W1;less annual water consumption and higher annual water use efficiency could be achieved under W0 treatment.The combination of Taikemai 30 and Zhengdan 958 under W1 treatment(winter wheat jointing water,flowering water and summer corn Mongolian water were 60 mm,respectively)had the highest annual yield and the best annual water use efficiency.The dry matter accumulation of Jimai 22+Denghai 605 and Jimai 22+Zhengdan 958 combinations was significant under W2 treatment,and the annual yield was the highest.The annual water consumption of Jimai 22+Denghai 605 under W0 treatment was significantly lower than that under irrigation treatment,and the annual water use efficiency was the best.The optimal annual water use efficiency was obtained under W1 treatment of Jimai 22+Zhengdan 958.In terms of comprehensive yield and water use efficiency,Taikemai 30+Zhengdan 958 was the best variety combination of winter wheat and summer maize,and W1 was the best irrigation amount.
