基于环境因子的笃斯越橘结实规律研究

Study on the Seed Bearing Rule of Vaccinium uliginosum L. Based on the Environmental Factors

对大兴安岭—黑河地区—小兴安岭一线开展笃斯越橘种质资源调查,了解野生资源现状。基于对笃斯越橘的形态、密度、产量、生境、物候等特征类型进行区分,发现郁闭度对笃斯越橘结实量的影响规律。随着郁闭度上升,株高上升、密度降低,平均单株结实量上升;随着郁闭度下降,株高降低、密度升高,单株结实量下降。

Through the investigation on germplasm resources of the Vaccinium uliginosum L. from Greater Higgnan Mountains to Heihe region and Xiaoxing＇an Mountains, to understand the status of wildlife resources. Based on distinguish of the characteristics including morphology, density, yield, habitat and phenology of V. uliginosum L. , the effect of enviromnental factors on the fruiting regularities of V. uliginosum L. was found. The average single tree seed yield increased with the increase of the canopy density and the height, and the decrease of the density. It will decrease otherwise it will reduce.
