沙棘,青海群众称黑刺,在西北、华北等地区的群众称醋柳和黄酸刺等,是胡颓子科落叶灌木或小乔木。在我国西北、华北、东北等地区有广泛的天然分布。1958年以来,我省各地广为引种栽植,实践证明它具有如下特点:(1)适应性强,生长快,根蘖旺,枝叶茂密,保持水土性能好;(2)侧根发达,并具丰富根瘤,利于改良土壤;(3)由于生长快、根蘖性强,为此收益早、用途广,枝丫可供编织和燃料,在优良的立地条件下长成小乔木可作民用建筑和家具用材等。据我们调查,1亩5年生左右的沙棘林头槎就可砍烧柴7,000-8,000市斤,平槎后4年左右又可砍第二槎,亩产增加至8,000～10,000市斤。依我省山区群众用柴情况,平均每人有1亩沙棘林,或每 Seabuckthorn, Qinghai masses said black thorn, in Northwest China and other regions of the masses that vinegar and yellow sour thorns, is the Elaeagnaceae deciduous shrubs or small trees. In our country northwest, north, northeast and other regions have a wide range of natural distribution. Since 1958, our province has been widely introduced and planted throughout. The practice has proved that it has the following characteristics: (1) strong adaptability, fast growth, strong root-tillering, dense foliage, good soil and water conservation performance; (2) Root nodules, conducive to improving the soil; (3) due to rapid growth, strong root tillering, for the benefits of early, wide use, branches for braiding and fuel, grow into small trees under excellent site conditions can be used for civil construction and furniture timber Wait. According to our survey, about 7,000-8,000 jin of seabuckthorn can be chopped on a 1-acre seabuckthorn plantation of about 5-year-old, and the second 槎 can be chopped down about 4 years after the mound. The yield per mu has increased from 8,000 to 10,000 kg. According to the situation in the province with the masses of firewood, each has an average of 1 acre seabuckthorn forest, or per
