Methods for Selecting and Preparing Land for Notoginseng Seedling Beds
Choose a shady slope on the back side, with a gradient of about 5°-10°, well-drained soil, loose texture, and a granular structure of red soil or brown-red soil. A slightly acidic soil with a pH of 5.5-7.0 is suitable, while heavy clay soil easily causes root rot and should not be used. Plow the land multiple times 2-3 months before sowing to a depth of 30 cm to let the soil weather, and at the same time thoroughly remove weeds, tree roots, and stones. In conjunction with plowing, apply 75 kg of lime per mu or 25 g/m2 of 50% carbendazim wettable powder mixed into the soil for soil disinfection treatment.
