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80.000%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0.320%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0.320%～0.700%,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. The prickly endothelium is hard and has the characteristics of maintaining the viability of the seeds for a long time. The germination rate of the untreated seeds is very low, and the germination effect of the wet sand is the most remarkable, and the emergence rate can reach more than 80.000%. The salt content has the relativity with the emergence and growth of Nitraria tazetta, should strengthen the water management at the seedling and seedling stage, wash the salt and alkali every week, salt within 0.320%, enter the growing period to meet the salt tolerance species Salt demand, suitable salt range 0.320% ~ 0.700%, improve seedling stress resistance.
