  • In order to study the effects of slow-release fertilizer and its application method on the photosynthetic characteristics of Phyllostachys violascens, the chlorophyll content and photosynthetic characteristics of Ph. violascens leaves were determined with three treatments, i.e. conventional fertilization, hole or furrow application of slow-release fertilizer. The results showed that the photosynthetic performance of Ph. violascens leaves under slow-release fertilizer treatment was significantly improved compared with conventional fertilization. The chlorophyll content, photosynthetic rate, stoma conductance, intercellular CO2 concentration and water use efficiency of Phyllostachys violascens leaves increased in different degrees compared with conventional fertilization, and the stomatal limitation decreased; the photosynthetic physiology of Phyllostachys violascens leaves had an obvious "age effect" in response to slow-release fertilizer application method; both 1-year-old and 2-year-old Phyllostachys violascens were significantly improved by furrow application of slow-release fertilizer. Therefore, it is recommended to use slow-release fertilizer by furrow application as the main method of external nutrient input in practice.
