摘要: 为探究在不同氮肥梯度下生物菌肥拌种对燕麦生长及产量的影响,以裸燕麦(晋燕13号)为材料在山西省右玉县进行了试验。结果表明:不同氮肥梯度下生物菌肥拌种对燕麦的株高、穗长、小穗数、穗粒数、穗粒重、千粒重和产量均有显著影响。其中A2处理(菌肥拌种+N 67.5 kg/hm2)与对照A1(清水拌种+N90 kg/hm2)相比,穗粒数、穗粒重和千粒重有所增加,分别提高1.86%、2.92%和1.36%,籽粒产量显著增产11.50%。

Abstract: The effect of seed dressing with biological bacterial fertilizer on the growth and yield of oats under different nitrogen gradient were studied in Youyu, Shanxi province. Plant height, ear length, number of spikelet, number of grain,grain weight, weight of 1 000 grains and yield were significantly affected. A2 treatment(seed dressing with bacterial fertilizer +N 67.5 kg/hm2) compared with the control A1(seed dressing with water +N 90 kg/hm2), number of grain, grain weight and weight of 1 000 grains were increased by 1.86%, 2.92% and 1.36%, and grain yield was significantly increased by 11.50%.
