摘　　要：采用不同强度平剪处理,研究机械抚育对笃斯越橘的植株形态、光合及结实的影响。结果表明,强、中(Tms、Tmm)处理对新枝长和枝粗具有显著的促进效应;机械抚育处理总体上改变了笃斯越橘光合速率、蒸腾速率和水分利用效率的日变化进程,均值与对照相比局部差异达到显著水平;Tms、Tmm处理对提高果实产量具有显著影响。机械抚育处理经过生长恢复后,笃斯越橘生长势、产量效果与留茬高度呈反向相关。Use different intensity trimming,studied the effects of mechanical tending on photosynthetic characteristics,Fruit characteristics and community diversity of Vaccinium uliginosum The results showed that strong and medium(Tms,Tmm)treatments significantly promoted the length and diameter of new branches;The mechanical tending treatment changed the diurnal variation process of photosynthetic rate,transpiration rate and water use efficiency of Vaccinium uliginosum in general,and the local difference between the mean value and the control reached a significant level;Tms and Tmm treatments had significant effects on fruit yield.After mechanical tending and growth recovery,the growth potential,yield effect and stubble height of Vaccinium uliginosum were inversely correlated.
