山杏是亚洲的特有树种,主要分布在北部(北纬30-52度)的干旱地区。在我国主要分布于东北、华北、西北地区。耐寒(可达-50℃低温)、抗旱(年降水量在200mm仍生长良好)。种仁为我国重要的出口土特产品,经济价值很高,是一种经济树种。如营造1ha山杏林,5年投资185元,第5年即可收回投资额,经营10年可纯收入7800多元。为北方干旱地区,经营投资少,收益大的种植业。并具有适应性强,可种植在荒山、瘠薄土地上,不与粮谷争地的特点,又能保持水土,对改善干旱地区生态条件具有重要作用。
Apricot is endemic to Asia and is mainly distributed in the arid region of the north (latitude 30-52 degrees north latitude). Mainly distributed in our country in northeast, north, northwest. Cold (up to -50 ℃ low temperature), drought (annual precipitation in 200mm still grow well). Seed kernels for our country’s exports of native products, high economic value, is an economic tree species. As to create 1ha mountain apricot forest, 5 years investment of 185 yuan, the first 5 years to recover the investment, operating 10 years net income of more than 7800 yuan. For the northern arid areas, operating less investment, large-gain farming. And has adaptability, can be planted in the barren hills, barren land, not compete with the characteristics of grain, but also to maintain soil and water, to improve the ecological conditions in arid areas play an important role.
