起垄方式对垄膜沟灌玉米产量及水分利用效率的影响

Effect of Ridging Way on Yield and Water Use Efficiency for Ridge With Plastic Film Mulching-furrow Irrigation of Corn

在武威市凉州区河水灌区试验观察了不同起垄方式对垄膜沟灌玉米产量及水分利用效率的影响,结果表明:采用垄膜沟灌模式,在垄高15 cm的条件下,当垄面宽为60 cm、沟宽为30 cm时,玉米的折合产量13 272.2 kg/hm2,较当地常规微垄种植模式增产55.96%;水分利用效率为22.95 kg/(mm.hm)2,较当地常规微垄种植模式增加18.49%。

The impact of different the ridging mode on yield and water use effciency of the ridge with plastic film mulching-furrow irrigation of corn was observed in Liangzhou river irrigation area of Wuwei. The results showed that the equivalent yield of the corn 13 272.2 kg/hm^2 and 55.96 % higher than of the compared to conventional micro ridge planting mode in a local using the ridge and the membrane furrow irrigation mode, and water use efficiency was 22.95 kg / （mm·hm^2） and 18.49% higher than of the compared to conventional micro ridge planting mode in a local.
