杨胡是荒漠地区的优良树种,它对恶劣的自然条件有较强的抗御能力。胡杨适应性强,耐盐碱和干旱瘠薄的土壤。木材供建筑,家具等用。胡杨生长速度比较快。我场七年生实生苗高达4.7米。胸径6厘米。胡杨根系极为发达,延伸广,扎的深.在自然情况下胡杨用根孽进行繁殖,人工插条繁殖很困难,种子繁殖出苗率过低而造成失败。但根孽繁殖赶不上林业生产上的需要,因此,提高种子繁殖的出苗率就成为林业生产生急需解决的问题。我场从1965年开展胡杨育苗,经过几年摸索,初步掌握了胡杨育苗技术,介绍如
Yang Hu is an excellent tree species in desert areas, it has strong resistance to bad natural conditions. Poplar highly adaptable, saline-alkali and arid infertile soil. Wood for construction, furniture and other purposes. Populus grow faster. My field of perennial seedlings up to 4.7 meters. Breast diameter 6 cm. Populus euphratica is extremely developed, extending a wide, deep tie.In nature, Populus euphratica propagation, propagation of artificial cuttings is very difficult, seed propagation rate is too low and cause failure. However, the multiplication of roots can not catch up with the needs of forestry production. Therefore, raising the seedling emergence rate has become an urgent problem to be solved in forestry production. My field from 1965 to carry out nursery stocking, after several years of exploration, initially mastered the Hu Yang nursery technology, such as introduction
