浙江省舟山县几年来进行了以黑极为主的大规模造林。该地群众历年来的采种经验如下:一、准确地掌握采种季节:黑松球果在寒露(阳历10月9日)前后开始成熟,采集时间以霜降(阳历10月24日),前后为最适宜。采集过早,松果难以开裂,种子也小而瘪。采得过晚,则果鳞全部裂开,种子飞散。二、选择母树:宜选择树龄7—10年生左右,树干端直、叶色鲜艳深绿以及无病 Zhoushan County, Zhejiang Province, carried out large-scale reforestation mainly in the black pole over the past few years. The local people’s harvesting experience over the years are as follows: First, accurately grasp the seed season: black pine cones in the cold dew (Gregorian calendar October 9) before and after the maturity, collection time to frost (solar calendar October 24), before and after suitable.

Second, choose the mother tree: should choose the age of 7-10 years old or so trunk straight, bright green leaves and disease-free
