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。
Taking plant seeds of Nitraria sibirica from Keriya River upstream of Keriya County of Hotan Prefecture in Xinjiang as the research object, using warm water soaking, stratification and sand germinating processing methods, the effects of different sowing methods on the seedling emergence rate and survival rate of the seeds were studied,for finding a high survival rate, propagation speed of the sowing and breeding methods,in order to provide experimental basis for the field experiment in the construction of the seeding and breeding base of the Nitraria sibirica. The results showed that when germination amount was more than 30%, they could be sown, Nitraria sibirica was sowed on April 25th , the emergence on May 7^th, seedlings on May 13^th basically sprouted completely,seedling emergence rate of different treatment methods was:warm water soaking 78%, layer deposition processing 72 %, sand germinating 67%, the average germination rate was 72.3 % of the year. Seed germination rate and survival rate of three processing methods were high.
