用“改良壕沟法”和“全根法”调查厚朴(Magnolia officinalis)根系后,厚朴属浅根性树种,主根不明显,侧根十分发达,垂直密集分布在10~40cm,占87.7%。根幅为冠幅的2~4倍,趋肥性和好气性强。为此对厚朴幼林要加强松土除草等抚育管理。
After investigating the roots of Magnolia officinalis with “Modified Trench Method” and “Total Root Method,” Magnolia officinalis is a shallow-rooted tree species with obvious main roots and lateral roots that are highly developed and are densely distributed vertically in 10-40 cm (87.7%). Root width of 2 to 4 times the crown, fertilizer and aerobic strong. To do this, we need to strengthen the management of the young magnolia grandiflora in the areas of loosening and weeding.
