摘  要：
以恒单188为试验玉米品种,2017年在吉林省西部半干旱地区滴灌试验田进行,试验设定了有膜和无膜两个处理组,5个氮水平:0、100 kg/hm2、200 kg/hm2、300 kg/hm2和400 kg/hm2,研究了不同施氮量对膜下滴灌和无膜滴灌栽培模式下玉米生长发育及产量的影响.结果表明:氮肥有助于玉米的生长,但过量施用氮肥可能会抑制玉米的生长和产量的形成.在整个生长期内,有膜滴灌玉米的生长发育都优于无膜滴灌.其中在玉米的生育后期,有膜滴灌处理下,施氮量300 kg/hm2对叶面积指数、干物质量积累以及产量的形成影响最为显著,这为玉米科学种植提供参考.

摘  要：
The Hengdan 188 was used as experimental maize variety, and it was carried out in the drip irrigation test field of western Jilin Province semi-arid area in 2017. The test set up two treatment groups with film mulching irrigation and no-film mulching irrigation, and 5 nitrogen levels: 0, 100 kg/hm2, 200 kg/hm2, 300 kg/hm2 and 400 kg/hm2, then, the effects of different nitrogen application rates on the growth and yield of maize under film mulching drip irrigation and no-film mulching drip irrigation were studied. The results showed that nitrogen fertilizer contributes to the growth of maize, but excessive application of nitrogen fertilizer may inhibit the growth and yield of maize. During the whole growth period, the growth and development of film mulching corn was better than that of no-film mulching drip irrigation. In the late growth stage of maize, the nitrogen application rate of 300 kg/hm2 treatment had the most significant influence on leaf area index, dry matter quality accumulation and yield formation,which provided a reference for corn scientific planting.
