沙棘(Hippophae rhamnoides L.)是胡颓子科灌木,我国“三北”地区约有1,000万亩沙棘天然林,对改善当地的生态环境起着重要的作用。由于沙棘果实已逐步加工成饮料、食品和医药等产品,使“三北”地区的山区农民找到了一条脱贫致富的门路,并且准备大量发展这一树种。为使新建的沙棘林采用优良种源进行育苗造林,避免盲目调种,由中国林业科学研究院林研所主持,于1986年春,在全国11个省区13个试验点进行了19个种源的沙棘育苗试验(见表1)。
Seabuckthorn (Hippophae rhamnoides L.) is an Elaeagnus family of shrubs, China’s “Three Norths” area of about 1,000 acres of seabuckthorn natural forest, to improve the local ecological environment plays an important role. Since the sea buckthorn fruits have been gradually processed into products such as beverages, foodstuffs and pharmaceuticals, mountainous areas in the “Three Norths” region have found a way out of poverty and become prosperous, and are ready to develop this tree species in large quantities. In order to enable the newly established seabuckthorn forest to adopt good provenance for nursery and afforestation and avoid blind seeding, the Forest Research Institute of the Chinese Academy of Forestry presided over it. In the spring of 1986, 19 provenances were obtained from 13 experimental sites in 11 provinces and autonomous regions in China Seabuckthorn seedling test (see Table 1).
