摘  要:
在呼和浩特市内蒙古农业大学教学农场设置人工土丘,分为0°坡区和14°坡区,两区各移植30株华北驼绒藜,移植植株生长1年后进行观察,结果表明:华北驼绒藜根颈存在漂移现象,坡区植株主茎基部被沙埋后在初始根颈之上的茎部产生不定根和不定芽,即发生了根颈向上漂移现象。随着埋沙厚度的增加,根颈可逐级上移,最大上移幅度7.3cm。沙埋促进了华北驼绒藜植株地上部的加速生长。

摘  要:
The experiment was carried out on the Experiment Farm,Inner Mongolia Agricultural University.Experiment plots were set on a human hill.One plot was at an incline of 0°,another was at 14°slope.30 plants of Ceratoides arborescens were transplanted in each plot.Measurement was conducted 1year later after transplanting.The results showed that root collar upward drifting happened.With the increase of thickness of sand buried,root collar drifting upwards step by step and the height of the move was up to 7.3cm.Plant growth was significantly promoted by root collar drifting.
