欧洲森林树木种子园大多是在第二次世界大战后建立起来的。实际上在七十年代才收获第一批种子。大多数欧洲国家希望到本世纪末种子园将能供应造林所需的全部种子。欧洲种子园的主要树种有欧洲赤松(Pinussilvestris L.)、欧洲云杉(Picea abies(L.)Ka-rst)、落叶松和冷杉(Abies spp)等。外来树种有美加黄杉、扭叶松和锡特加云杉等。欧洲赤松的最有害的虫种是松球果象虫(Pissodes val-idirostris Gyll.),球果被害率有时可达25~
Most of the European forest tree seed orchards were established after the Second World War. In fact, the first seeds were harvested in the seventies. Most European countries hope that the Seed Garden will be able to supply all the seeds needed for afforestation by the end of this century. The main species of European seed orchard are Pinus densiflora, Picea abies (L.) Ka-rst, larch and Abies spp. Exotic species are the United States and Canada Douglas Fir, Twisted pine and Sitka spruce and so on. The most harmful pest of Pinus sylvestris is Pissodes val-idirostris Gyll. The damage rate of cones can sometimes reach 25 ~
