黄土干旱阳坡植被恢复种子处理技术研究

Seed Treatment of Vegetation Restoration in the Drought and Sunny Slopes of the Loess

针对黄土干旱阳坡植被恢复中的缺水问题,以刺槐种子、侧柏种子为例进行了室内水瓶辅助法播种试验和田间保水囊法播种试验,研究了改善种子水分环境的技术手段。结果表明:利用以纸浆为主要成分制作而成的保水囊进行播种,能有效地提高刺槐种子的出苗率,但对侧柏种子没有明显效果。

According to the water shortage problems in the drought and sunny slopes of the loess,the sowing tests through assistance of room water bottle and water conservation bag in field were carried out using Black locust seed and Platycladus orientalis seed.The technique measurements to improve seed moisture environment were studied.The results showed that water conservation bag made from paper pulp as main component could enhance the seedling emergence rate of black locust seed,and had no effect on seeds platycladus orientalis.
