Polygonum multiflorum is a fertilizer plant. It should be used as a base fertilizer and top dressing. Top dressing uses organic fertilizer in the early stage, phosphorus and potassium fertilizer in the middle period, and no fertilizer in the later period. When the plant survives to grow new roots, the manure per acre will be used to excrete 1000-1500 kg of manure. Then, depending on the growth condition of the plant, the fertilizer can be applied again, and the application can be performed 2500 kg per acre. When seedlings grow to more than 1m, no nitrogen fertilizer is generally applied. After September, when the roots begin to form and grow, they will be re-applied with P and K fertilizers, apply 3000kg of manure and ash mixed fertilizer, 50-60kg of superphosphate and 40-50kg of potassium chloride. Apply on both sides or around the plant. Each year after the spring and autumn fertilization 1 times, mainly organic fertilizer, the appropriate amount of phosphorus and potassium fertilizer. Every top dressing is combined with cultivating soil to remove weeds and prevent soil compaction.

2. When the branches and branches of F. multiflorum grow to 30cm, they are inserted into a bamboo strip or a small piece of wood, inserted into a fence-like or tripod-like shape, and the vine is wound clockwise around it. The loosened area is tied with a rope. One vine was left per plant, and the excess vines were removed, and the ramets were kept at 1m or more in order to facilitate the ventilation of the lower layers of the plants. If the growth is too lush, it can be properly topping, reduce nutrient consumption, generally 5 to 6 times a year, 7 times in high yield fields.
