摘要
为给引种栽培野生东北百合提供参考依据,对其种群结构、生境及物候学特征进行了调查研究。结果表明:东北百合于4月下旬出苗,10月上旬果实成熟,展叶期到花期是其重要的观赏时期;东北百合按其生长发育状况可分3种类型,即可正常开花结果型、只长轮叶而不抽生花茎型和只长基生叶型;展叶后期至子房膨大后期其郁闭度在0.8以上,林间的光照强度、空气湿度同林外的差异很大;能完成生育周期的东北百合适生于紧实度在6.80～14.60kg之间的土层中,土壤的通气度在32.32%左右,容重在1.22g.cm-3左右,田间含水量在33.19%左右,土壤中有机质的含量在2.07左右,pH值在5.85左右。
In order to provide a reference for introducting and cultivating Lilium distichum,population structure,habitat and phenology characters in L.distichum were investigated and researched.The results showed that L.distichum seedling became to sprout from late April,ripen at early October,and the period from leaf expanding period to flowering was important ornamental stage.The pattern of L.distichum by growth status could be classified into 3 types of the natural growth type,the having-vane and no scape type and the type with only basal leave.Canopy density was over 0.8 from the late leaves expanding period to the late ovary enlarging period,and light intensity and air humidity compared were very different from those outside the forest.L.distichum was able to complete the reproductive cycle,under the conditions of soil compaction degree of 6.80-14.60 kg,soil aeration degree about 32.32%,soil bulk density about 1.22 g/cm^3,water content in soil about 33.19%,organic matter content in soil about 2.07,pH value about 5.85.
