摘要
以蒙啤1号、甘啤4号2个品种为试材,设0,90,180,270 kg·hm^(-2)四个氮肥水平,研究了不同施氮水平对内蒙古东部灌区春大麦干物质积累及转运的影响.结果表明,随施氮水平的增加,2个品种大麦各器官干物质重量先增后降,在180 kg·hm^(-2)施氮水平下最大;叶片、茎秆的干物质转运量先增后降,在180 kg·hm^(-2)处理下达到最大;其转运量对籽粒的贡献率逐渐下降.
The effects of different nitrogen application rates on dry matter accumulation and translocation of spring Barley in eastern Inner Mongolia were studied with two spring Barley cultivars of Mengpi 1 and Ganpi 4 as materials,and different rates（0 kg/hm^-2,90 kg/hm^-2,180 kg/hm^-2and 270 kg/hm^-2） were applied in the field. The results showed that the weight of organs dry matter of two spring Barley cultivars first increased and then dropped with the increment of nitrogen application rate. The weight of organs dry matter was highest, when the nitrogen application rate was 180kg/hm^-2.The translocation amounts of leaf and stem first increased and then dropped, and it was highest when the nitrogen application rate was 180 kg/hm^-2. Its contribution rates of translocation amount to grains decreased gradually with the increment of nitrogen application rate.
