从白刺果实形态学特性的角度入手,结合优势株选择、优质核果筛选、优质苗木筛选,进行白刺种质资源的提纯,具有较理想的效果。白刺内果皮坚硬,具有长期保持种子生活力的特性,不经处理的种子发芽率很低,湿沙催芽效果最为显著,出苗率可达到80%以上。盐分含量对白刺的出苗和生长具有相关性,在出苗期和幼苗期应加强水分管理,每周灌水进行洗盐压碱,适盐范围0.32%以内,进入生长期,以满足耐盐性树种对盐分的需求,适盐范围0.32%～0.70%,提高苗木抗逆性。
From the perspective of the morphological characteristics of Nitraria tangutorum, combining with the selection of dominant strains, selection of high quality drupe and high-quality seedling screening, it is more effective to purify Nitraria tibetanaceae germplasm resources. Prickly pear pericarp hard, with long-term to maintain the characteristics of seed vitality, seed germination rate is very low, wet sand sprouting effect is the most obvious, the emergence rate of up to 80%. Salt content had a correlation with the emergence and growth of Nitraria tazetta, water management should be strengthened in the seedling and seedling stage, wash salt and alkali every week, salt within 0.32%, enter the growing stage to meet the salt tolerance species Salt demand, suitable salt range 0.32% ~ 0.70%, improve nursery stress resistance.
