Experiment on Seedling Cultivation by Root Cuttings of Bretschneidera sinensis

In February 2019, 10 cm and 15 cm lateral roots from 3-5-year Bretschneidera sinensi s were treated by rooting agent and covered in seedbed with 2 and 5 cm soil. In February 2020, 10 cm lateral roots from different part were covered in seedbed with 2 cm soil. In November of the current year, determinations were carried out on survival rate. The result demonstrated that different cuttings covered with 2 cm soil had higher survival rate. The survival rates of cuttings with the first and second segments of lateral roots were 93.8% and 38.8% respectively.
