The objective of the present study was to determine effects of climbing truss and the suitable planting density of vine tea in Tu commune, Dong Giang district, Quang Nam province. The experiments were implemented from november 2018 to december 2019. The experiments were arranged in split-splot method. Two different climbing trusses patterns were arranged in a large plots. Three different planting densities (1 plants per m2, 2 plants per m2 and 3 plants per m2) were arranged in a small plots, 3 replicates. The monitoring indicators are plant's height, number of grade 1 branches per plant, number of leaves per grade 1 branches, real fresh, real dry yield per plant and per hectare. The results of the study indicated that real fresh and dry yields per plant and per hectare in the climbing truss were higher in the non-climbing truss (P<
0.05). Real fresh and dry yields per hectare of density of 3 plants per m2 were significantly higher than that of 1 plants per m2 and 2 plants per m2 (P<
0.05). Thus, it was recommended to cultivate three plants per square meter (0.33 m x 1.0 m
equal 30.000 plants per ha) in combination with making A-shaped climbing truss for the highest production efficiency.Trong nghiên cứu này, ảnh hưởng của hình thức giàn leo và mật độ trồng chè dây đến sinh trưởng, phát triển và năng suất trên địa bàn xã Tư, huyện Đông Giang, tỉnh Quảng Nam đã được nghiên cứu.
