摘要: 为研究施用生物菌肥对燕麦叶片生理特性及产量的影响,在温室不同类型土壤条件下,设置4个处理,分别是R(壤土)、RM(壤土+生物菌肥)、Y(盐碱土)和YM(盐碱土+生物菌肥)。结果表明:在壤土和盐碱土条件下施用生物菌肥,可以提高燕麦叶片的SPAD值、净光合速率、气孔导度、蒸腾速率、水分利用效率,降低燕麦叶片胞间CO2浓度。此外,生物菌肥可以增强燕麦的抗逆性,生理特性表现为丙二醛、超氧化物歧化酶活性及游离脯氨酸含量降低,尤以抽穗期的效果最为明显。壤土条件下,施用生物菌肥燕麦的产量降低,而在盐碱条件下施用生物菌肥可提高其鲜重和干重。

关键词: 燕麦, 盐碱土, 生物菌肥, 生理特性

Abstract: This experiment studied the effects of applying bio-fertilizer on the physiological characteristics and yield of oats planted in different types of soil.By conducting the test in the greenhouse,four treatments were designed:R (loam),RM (loam+bio-fertilizer),Y(saline-alkali soil) and YM(saline-alkali soil+bio-fertilizer).The results showed that the SPAD value,A,Gs,E and WUE of oat blades are increased after applying the bio-fertilizer in loam and saline-alkali soil,At the same time,the Ci of oat blades is decreased.After the application of bio-fertilizer,the stress resistance of oats was enhanced,which showed that the contents of MDA,SOD and Pro are all decreased,and this effect was most obvious at the heading stage.With the application of bio-fertilizer,the yield of oats decreased in loam soil,but the fresh-dry weight increased after using the bio-fertilizer in saline-alkali soil.

Key words: Oats, Saline alkali soil, Bio-fertilizer, Physiological property
