摘要: 在内蒙古奈曼旗对沙地春小麦进行了氮肥施量试验。结果表明,不同施氮量(尿素15.0~51.5g·m-2)对沙地春小麦穗粒数、千粒重、有效小穗数及其百分率、籽粒产量、生物产量的影响具有显著差异,但对成穗数、株高的影响差异不明显。产量水平以施氮量为37.5g·m-2时最高。

关键词: 沙地, 春小麦, 施氮量, 株穗性状, 产量

Abstract: The experiment was carried out in Naiman Station, designing six levels (15.0 g·m-2, 21.5 g·m-2, 30.0 g·m-2, 37.5 g·m-2, 45.0 g·m-2, 51.5 g·m-2) of treatments on the spring wheat growth in sandy farm land. The results show that the nitrogenous fertilizer affects the grain number, 1 000 grain weight, effective spikes, yield and biomass significantly, but does not on the ear amount and the height of wheat. To apply 37.5 g·m-2 amount of urea produced the highest yield of grain (564.79 g·m-2) and above ground biomass (1 511 g·m-2).

Key words: Sandland, Spring wheat, Nitrogen fertilizer amount, Ear character, Grain yield
