摘要
1988～1990年在华北落叶松山地和平地两个种子园中研究了花粉飞散的空间和时间变化规律,分析了这种变化与气温和湿度的关系,并据此讨论了华北落叶松种子园的花粉管理问题。
The pollen dispersal of Larix principis-rupprechtii Mayr.and its daily and hourly changes in relation to temperature and moisture conditions during the pollen shedding period were studied in two seed orchards for three successive years,1988 ~1990.More attention was paid to the transportation and dispersal features of pollen both inside and outside the seed orchards under even and mountainous conditions.Ideas for pollen management of seed orchards were suggested on the basis of the study.
