摘要
[目的]研究沙枣是否可引种至吉林西部盐碱地区,以改善当地生态环境。[方法]将采自宁夏的沙枣种子播种到北华大学林学院苗圃及实习基地,进行物候期和植株生长状态观察、抗逆性以及不同基质扦插和不同嫁接方法与成活率的关系等研究。[结果]沙枣能够适应吉林地区的气候条件而生长发育健壮;3种防寒措施中,土埋无冻害,草帘覆盖和缠稻草把虽分别有2.8%、3.9%的死亡率,但冻害程度轻微,可以正常越冬。同时沙枣在吉林地区同样具有较好的抗盐碱、抗旱涝性。沙枣扦插和嫁接获得了成功,为其快速大面积种植提供了条件,同时得出了不同基质扦插的生根率。[结论]沙枣可引种至吉林省西部盐碱地区栽植。
[ Objective ] The experiment aimed to explore the possibility of introducing Elaeagnus angustifolia L. in saline land of West Jilin Province for improving local ecological environment. [ 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.
