Abstract:

Four sample plots were built in high-yield bamboo forest in 1996, the bamboo nutrient solution was injected into the base of bamboo culm in three plots, the other plot was used as control.In 1997, the photosynthetic characteristics of leaves at each age were studied.The results showed that the specific weight of bamboo leaf, chlorophyll content and dark respiration rate and net photosynthetic rate of leaves increased and light respiration, CO2 compensation point and light compensation point obviously decreased after injecting nutrient solution.The changes in these indexes were useful to increase photosynthetic function, to improve accumulation of organic matter and cultivate high and stable yield bamboo forest.

Key words: Phyllostachys heterocycla cv. pubescens, Nutrient solution, Photosynthetic characteristic
