摘要
通过大田试验,研究了玉米不同带耕沟播模式对灌溉效率和产量及水分利用效率的影响。结果表明,不同玉米带耕沟播模式可以显著提高灌溉效率和水分利用效率,并随着宽带距离增加,灌溉效率和水分利用效率呈提高趋势,但产量呈下降趋势。与传统60 cm等行距漫灌模式相比,MSⅠ(30 cm+150 cm)灌溉效率提高155.5%,灌水利用效率提高192.5%,水分利用效率提高122.5%,产量提高了14.5%,具有实际应用价值。
The paper studied the effect of different belt tillage and furrow planting of maize on yield, irrigation efficiency and water use efficiency in field experiment. The results showed that different belt tillage and furrow planting mode could significantly increase irrigation efficiency and water use efficiency. With the increase of belt distance, the irrigation efficiency and water use efficiency increased, while the yield declined. Compared with traditional 60 cm equidistance flooding irrigation mode, MSⅠ（30 cm＋150 cm）increased irrigation efficiency, irrigation use efficiency, water use efficiency and yield by 155.5%, 192.5%, 122.5% and 14.5%,respectively, which was suitable for practical application.
