| 摘 要： | 本文分析了白刺属不同类型种子的主要特征。在种子催芽方面,提出既简单又省工省时的冷水浸种催芽方法,平均场圃发芽率可达61.8%。采自民勤的五种白刺种子,在兰州北山黄土丘陵区引种造林试验,采取集水保墒措施后,营造白刺林已获得成功,保存率最高的唐古特白刺可达81.0%,匍匐地面的白刺枝叶,可有效地起到护坡及控制水土流失作用。

| Abstract: | Nitraria Tangutorum is a shrub with great economic value. The paperanalyzes the primary features of Nitraria's seeds, puts forward a seed-soa-king mathod with cold water to accelerate germination. This method, withless labour and time, makes the average germination percentage reach to61.8%. In the loess hilly country in the north of Lanzhou, there is a suc-cessful afforestation test with Nitraria, by the aid of collecting rainoff andpreserving soil moisture, the preservation percentage of Nitraria Tangutorumreaches as 81.0%. The branchea and leaves crept over ground can effectivelyprevent water and soil from erosion. |
