以新疆和田地区于田县的克里雅河上游分布的西伯利亚白刺种子为试材,进行温水浸种催芽、层积处理和沙藏催芽等3种处理方法,研究了不同播种育苗方法对白刺种子出苗率和成活率的影响,以期找到使育苗成活率高、繁殖速度快的播种育苗方法,对白刺属植物播种育苗基地建设方面提供实地试验基础。结果表明:对白刺种子进行温水浸种催芽、层积处理和沙藏催芽后,当有30%以上的种子露白时即可播种,当年4月25日播种,5月7日出苗,5月13日苗木基本出齐,不同处理方法出苗率分别为温水浸种催芽78%、层积处理72%、沙藏催芽67%,平均出苗率72.3%。3种处理方法的种子出苗率和成活率均较高。
The seedlings of Nitraria sibirica distributed in the upper reaches of the Keriya River in Yutian County, Hotan were investigated by three methods: warm water soaking, germination, stratification and sand deposition. Rate and survival rate, in order to find the seedling raising method which has high seedling survival rate and high reproductive rate, and provides the field test basis for the construction of the seedbed planting acanthopanax seabuckthorn. The results showed that when prickly ash seeds were soaked in warm water, germination, stratification and sand storage were promoted, when more than 30% of the seeds were exposed to the white, they could be planted, then sown on April 25, germinated on May 7, and seedlings on May 13 The results showed that the germination rate of different treatments was 78% for warm water soaking, 72% for stratification, 67% for sand accumulation, and the average germination rate was 72.3%. The seed germination rate and survival rate of the three treatments were higher.
