Embodiment
[0034] The southern yew is asexually propagated by cuttings to expand the cultivation area.
[0035] 1. Cutting time
[0036] Usually, cuttings can be carried out throughout the year. Spring is the most favorable time for cuttings to take root. From February to March when the mother tree has not germinated, followed by September to October when the sun is strong, the temperature is high, and the callus is formed quickly. For the suitable cutting season. The best conditions for cutting are that the average daily air temperature is 18-26°C, the duration of the temperature ≥30°C does not exceed 6 hours, the average daily soil temperature is ≥10°C, and the relative air humidity is ≥70%.
[0037] 2. Selection of cuttings
[0038] Usually, 1-4 years old lignified germination and seedling branches are selected. The annual sprouting tillers contain less substances that inhibit rooting, and the rooting rate of cuttings is higher; the young mother trees grow vigorously, and the conten...
