摘　　要：在自然降水的条件下,研究了4种不同处理对板栗全年光合速率和蒸腾速率的影响.结果表明:20、10mg/L浓度的“施丰乐”溶液,可以提高板栗的光合速率,降低蒸腾速率,从而使水分利用效率得到很大的提高,这在干旱缺水的条件下,对提高板栗产量很有效.Under natural rainfall, the effects of four different “Shifengle” treatments on photosynthetic characteristics, water use efficiency and products of Castanea mollissima Blume were studied. It was showed that good water utility has positive effect on the products of Castanea mollissima Blume, which can be achieved by the increase of photosynthetic rates and water use efficiency, and by the decrease of transpiration rates of 20,10 mg L concentrations.
