After spreading evenly, the base fertilizer is ploughed 30 to 40cm, raked fine and leveled for border, the border width is 1 to 1.3 meters.

2. Middle ploughing and weeding: sand ginseng seedlings select cloudy days to remove weeds, set seedlings combined with topdressing and loosening soil to weed, plants should stop weeding to avoid breaking stems and branches after sealing, drainage should be paid attention to in rainy days, and proper watering can be done in dry days.

3. Rational fertilization: application of 10% light human feces or 2% urea water at seedling stage, topdressing once after seedling setting, 1000 kg per mu of soil fertilizer before winter, once after seedling emergence in the second year, 1000 kg per mu from June to July before flowering and mixed with a small amount of phosphorus and potassium fertilizer.

4. Topping at the right time: sand ginseng grows rapidly from the second year. In order to reduce nutrient consumption and promote root growth, it can be topped when the plant height is 40-50 cm.
