Nowaday ginger plants have been interested, exploitation and use for target spices, medicinal herbs and foods in many Asian countries as well as worldwide. In recent years the demand for ginger and its products is increasing in the direction of spices, food and medicines. But in fact ginger production in the Northern provinces reflects a backward farming methods, no advanced technical processes. This is also the main cause of reduced productivity, quality and effectiveness of ginger cultivation. Research a basic factors of ginger cultivation techniques are promising solutions for variety QT1 as top priority in order to enhance productivity, for improving efficiency of ginger cultivation in the northern provinces in the coming years. On this basis, the research team conducted building a integrated technical solutions to enhance productivity for ginger QT1 through research contents are seasonality, density, quantity and type of data fertilizer, suitable cover material. The results showed that ginger production in seasonal frame 29/2-15/3 with spacing 50cm  15 cm, apply fertilizer N, P2O5, K2O and organic micro, corresponding to 200-300 kg, 120-150 kg, 200-300 kg and 2000 kg/ha, and use straw or black plastic cover materials bed surface is the solution basic techniques, important to improve productivity for QT1 ginger variety in Bac Kan and Hoa Binh provivinces.
