| 摘 要： | 本文以浙江省千岛湖姥山林场柏木种子园为对象,对柏木球花及花粉的生态学特性进行了研究结果表明,柏木的雌雄球花在树冠中呈成层分布;降雨时,雄球花对花粉具有保护功能;柏木花粉体积小,重量轻,花粉量大,花粉的散发受气温、风力、相对湿度和气压的综合影响,其中气温是主导因子,风左右着花粉的传播,降雨加速花粉的沉降。其垂直空间分布和水平空间分布都有一定的规律性,针对上述特性,提出了经营柏木种子园的有关建议。

| Abstract: | Based on the investigation and analysis of the Cupressus funebris seed orchard at Laoshan Island in the Qiandao Lake, Zhejiang province, the ecological characteristics of the male cone, female cone and pollen have been studied. The results show that the distribution of the male and female cones in the crown is stratified: the male cone has a function to protect the pollen from the rain: the pollen is small in size. light in weight, and tremendous in quantity: the dispersal of the pollen is affected by the temperature, wind speed, relative humidity and air pressure, and the temperature is the leading factor, the wind controls the pollen dispersal and the precipitation accelerates the pollen sedimentation: and the vertical and horizontal distribution of the pollen has its regular patterns. Some suggestions for the seed orchard establishment and management have been put forward. |
