[Method] The Elaeagnus angustifolia L. from Ningxia Province were sown in nursery and practice base of Forestry College in Beihua University to observe their phenophase, growth state, stress resistance and study the relations between survival rate and different cutting medium, grafting methods. [Result] Elaeagnus angustifolia L. could adapt to climate condition in Jilin area and grow well . Among 3 cold-proof measures, there was no freezing injury by soil burial method, although there was 2.8% and 3.9% mortality by covering grassy marshland and winding straw, the cold injury degree was light, so they could go through winter normally. Meanwhile, Elaeagnus angustifolia L. had good saline-alkali tolerance, drought resistance and flood resistance. The successful cutting and graft of Elaeagnus angustifolia L. provided a condition for planting in large-scale and knew the rooting rate of different cutting medium. [Conclusion] Elaeagnus angustifolia L. could be introduced to plant in West Jilin Province.展开更多
