Abstract
[Objective]The effects of brewer's spent grains-typed bio-organic fertilizer on cowpea photosynthesis characteristics were studied.[Method]Field plot experiments were conducted which had four treatments including natural compost,pure chemical fertilizer,brewer's spent grains-typed bio-organic fertilizer,double effect exquisite bio-organic fertilizer.[Result]Net photosynthetic rate,intercellular CO2 concentration and content of chlorophyll of cowpea functional leaves were uppermost during flower buds.[Conclusion]Brewer's spent grains-typed bioorganic fertilizer could increase net photosynthetic rate in later stage of cowpea growth,improve the content of chlorophyll of functional leaves,decrease transpiration rate,and it had little effect on stomata conductance of functional leaves.
