Abstract:

【Objective】 This research aims to understand the effects of microbial agents combined with nitrogen fertilizer on the photosynthetic characteristics and yield of wheat. 【Methods】 Field experiments were conducted on the treatment of microbial agents combined with nitrogen fertilizer.A comparative study was conducted on the chlorophyll SPAD value, leaf area index, photosynthetic fluorescence index, and yield of wheat under different treatments. 【Results】 The photosynthetic characteristics of wheat leaves varied among different treatments.There was no significant difference in chlorophyll SPAD value, initial fluorescence intensity, and maximum photochemical efficiency among the treatments.The chlorophyll SPAD value of PN2 was the highest in the combination treatment of full nitrogen fertilizer and microbial agent, and the chlorophyll SPAD value during the flowering and filling stages increased by 0.68 and 0.70, respectively, compared to the full nitrogen fertilizer treatment without microbial agent.The leaf area index of PN2 treated with a combination of full nitrogen fertilizer and microbial agents was the highest, significantly higher than that of PN0 treated without nitrogen fertilizer.The leaf area index during the flowering and filling stages increased by 38.59% and 37.70%, respectively, compared to PN0.The net photosynthetic rate of PN2 treated with a combination of full nitrogen fertilizer and microbial agents was higher than that of PN1, PN3, and PN4 treatments, and significantly higher than that of PN0 treatment.The combination of full nitrogen fertilizer and microbial agents resulted in the highest PN2, significantly higher than other treatments, with an increase of 41.63%, 9.53%, 20.65%, and 22.70% compared to PN0, PN1, PN3, and PN4 treatments, respectively. 【Conclusion】 The combination of full nitrogen fertilizer and microbial agents showed the best comprehensive performance in wheat photosynthetic characteristics and yield.

摘要:

【目的】 研究微生物菌剂与氮肥配施对小麦光合特性及产量的影响。【方法】 设置微生物菌剂与氮肥配施处理的田间试验,比较不同处理小麦叶绿素SPAD值、叶面积指数、光合荧光指标及产量的变化。【结果】 不同处理间小麦叶片光合特性表现亦不同。各处理间叶绿素SPAD值、初始荧光强度、最大光化学效率差异不显著。全量氮肥与微生物菌剂配施处理PN2叶绿素SPAD值最高,小麦开花期、灌浆期叶绿素SPAD值较未添加微生物菌剂的全量氮肥处理PN1分别增加0.68、0.70。全量氮肥与微生物菌剂配施处理PN2的叶面积指数最高,显著高于不施氮肥处理PN0,开花期、灌浆期叶面积指数分别较PN0增加了38.59%、37.70%。全量氮肥与微生物菌剂配施处理PN2净光合速率高于PN1、PN3和PN4处理,显著高于PN0处理。全量氮肥与微生物菌剂配施处理PN2产量最高,显著高于其他处理,分别较PN0、PN1、PN3和PN4处理增加了41.63%、9.53%、20.65%和22.70%。【结论】 全量氮肥与微生物菌剂配施处理小麦光合特性和产量综合表现最佳。
