Abstract:

To study the effect of different cultivation measures on the yield of Aucklandia lappa in order to provide scientific basis for GAP cultivation techniques. To adopt L9(34) orthogonal design to study the effect of different densities, base fertilizer, additional fertilizer, collecting time on yield of Aucklandia lappa by analyzing multiple-factor and single-factor. The results showed that the suitable measures of high yield of Aucklandia lappa were as follows: density of 20 cm×30 cm, 30000 kg farmyard manure added 450 kg compound fertilizer each hm2 as base fertilizer, 450 kg compound fertilizer and 300 kg urea as additional fertilizer each hm2, 10-11 months as collecting time.
