| 英文摘要 | To clarify the mechanisms underlying the improvement of Trichoderma on Chinese wolfberry (Lycium chinense) growth under saline stress,we analyzed the effects of application of organic fertilizer,Trichoderma agent and fertilizer on nitrogen uptake,assimilation,accumulation and use efficiency in Chinese wolfberry,based on a pot experiment with coastal saline soil.The organic fertilizer was the sterilization substance of Trichoderma fertilizer without viable Trichoderma,without any difference in the content of nutrients (such as nitrogen,phosphorus and potassium) between them.The results showed that the application of organic fertilizer,Trichoderma agent and fertilizer significantly increased NO_3~- and NH_4~+ influx rate in meristematic zone and NO_3~- influx rate in maturation zone of roots.The magnitude of such enhancement was greater in the application with Trichoderma fertilizer than organic fertilizer.Compared with the control,the application of Trichoderma agent and fertilizer significantly increased root,stem and leaf biomass and nitrogen content as well as plant nitrogen accumulation,strengthened root and leaf nitrate reductase,nitrite reductase and glutamine synthetase activities,and elevated nitrogen uptake efficiency,photosynthetic rate,stable carbon isotope abundance and photosynthetic nitrogen use efficiency.For all those variables,the beneficial effect was obviously stronger in the application with Trichoderma fertilizer than organic fertilizer.Therefore,Trichoderma facilitated nitrogen uptake,assimilation and accumulation in Chinese wolfberry under saline stress,improved photosynthetic carbon fixation ability and nitrogen use efficiency,and ultimately promoted plant growth. |
