摘要:
在控根栽培模式下,采用土钻法对6年生桂花嫁接苗的根系分布和季节动态进行研究。结果表明:一年中,随着时间的变化,桂花根系长度、根系体积、根长密度都呈增长趋势;须根萌发明显,细根增多,根系分布层上移,主要集中在0~10 cm土壤深度,说明控根容器对桂花根系构型产生一定影响。
Abstract:
Under the rootcontrolling cultivation conditions, the distribution characteristics and seasonal dynamics of sixyearold Osmanthus fragrans seedling root system were studied by using soil drilling. The results showed that root length, volume and density were increased with time passed. Meanwhile, fibrous roots sprouted obviously and absorbing roots increased. Root distribution layer was updrifted and concentrated in 0—10 cm soil depth mostly which indicated that there were certain effects on root configuration under rootcontrolling cultivation.
