The invention provides a process for quickly propagating a large quantity complete oil tea clone plants with roots by tissue culture, which comprises the steps of secondary culture medium screening and hormone combination, seedling strengthening culture medium screening and hormone combination, root preprocessing, and rooting culture medium screening and hormone combination, wherein WPM+BA (Woody Plant Medium and Benzyladenine, 3-7mg/L), IBA (Indol Butyric Acid, 0.1-2mg/L) and ZT (Zeatin, 0.05-2mg/L) are used as secondary culture media for propagation, the propagation period is shortened to 30-40 days, and the propagation coefficient reaches 4.2-9.1; WPM+IBA (0.1-2mg/L) and biotin (0.5-3mg/L) are used as seedling strengthening culture media for strengthening seedlings, and seedlings can take root after 20-25 days; and after being treated with IBA, tissue culture seedlings which are 2-4cm in height are directly inoculated on the culture media of MS (Murashige and Skoog medium, 1/4-1) and AC (Activated Carbon, 200-600), the tissue culture seedlings take root and form complete plants after 25-3 0days, and the rooting rate reaches more than 85%.
