Abstract
The experiment was carried out with 3 kinds of biological products (Eco-garden, Ambio, Vietfarm) on Camellia Phania (1st year). The results show that all three types of growth factors increase tree height, stem diameter, leaf speed faster than control (no fertilizer). In particular, ecological garden products increase fastest in the above criteria with a growth rate of 1.04 cm/ month, 3.25 cm/ month, 4.33 cm/ month corresponding to three stages. 0 - 60 days, 60 - 120 days, 120 - 180 days; the stem diameter increase is 2.6mm/ 6 months; leaf yields reached 1.07 leaves/ month, 1.09 leaves/ month, 1.32 leaves/ month respectively. In addition, the application of bio-preparations for Camellia Phania tea reduced the green leafhopper and gray-scale disease (grade 1) compared with the control (grade 2).
