适用于新疆干旱荒漠区的沙棘立体遮荫育苗法

在新疆干旱荒漠区的环境特别恶劣地段，需要培育抗逆性强且经济效益较好的沙棘实生苗造林。经试验研究，在沙棘播种前10~15d于沙棘行边稀疏地播种早熟玉米，进行沙棘立体遮荫挡风育苗，既能提高沙棘出苗率和保苗量，又能在后期玉米成熟砍去后，满足沙棘对强光照的需要。这一方法比起大田常规育苗和固定温棚育苗，出苗率高，苗高较常规育苗提高14cm ，且前期投入少，后期综合收益大，亩效益较常规育苗提高3113元。立体遮荫育苗法，是适用于新疆干旱荒漠区沙棘播种育苗的有效措施。

Three-dimensional Shade Seedling Nursing Method of Hippophae Rhamnoides L. Suitable for Arid Desert Area in Xinjiang Autonomous Region

In particularly bad area with very adverse circumstances in acrid desert region, it is needed to afforest by culturing seedling plant of Hippophae rhamnoides L. with strong stress resistance and good economic benefit. The study showed that 10~15 days before the seabuckthorn sowing planting the early-maturing maize by the side of seabuckthorn rows for the three-dimensional shade seedling nursing with windbreak effect can not only improve the rate of emergence and seedling survival of Hippophae rhamnoides L., but also meet Hippophae rhamnoides L.’ need for strong illumination after the harvest of maize. Compared with regular field seeding and greenhouse nursery, this practice is characterized by high rate of emergence, high growth （about 14cm more than normal nursery）, less initial input and high final comprehensive gains （about 3113 yuan increased per mu）. So the three-dimensional shade nursing method serves as an effective measure for Hippophae rhamnoides L. seeding and seedling nursing in ar-id desert area.
