(1) Cultivating and weeding. After Polygonum multiflorum sprouts in early spring, weeds grow densely, and cultivating and weeding must be carried out in time. From now on, this should be done every 20 days to 1 month. Cultivating should be stopped after the rows are closed.

(2) Top dressing. After planting, during the growth period, top dressing is required three times a year. The first time is in mid-to-late April. At this time, the Polygonum multiflorum vines enter a vigorous period of growth and require nitrogen fertilizer. Apply 2,000 kg of decomposed human and animal manure or 20 kg of urea every 667 m2; The second time is in late June, when small roots form and enter the initial stage of thickening growth. Phosphorus and potassium fertilizers are needed. Apply 40 kg of superphosphate, 20 kg of potassium chloride, or 30 kg of compound fertilizer every 667 m2; the third time In mid-to-late October, this is the plant recovery period and requires base fertilizer. Apply 2,500 kg of decomposed manure or soil fertilizer and 25 kg of superphosphate every 667 m2. To apply fertilizer, apply it in a shallow trench around the rhizosphere of the plant and cover it with soil. The last time can be combined with mulching and soil cultivation to facilitate overwintering.

(3) Irrigation and drainage. Polygonum multiflorum is afraid of drought and water accumulation. During the growth period, the soil must be kept moist at all times. Drainage ditches should be paid attention to after rain to prevent water accumulation in the field and promote its strong growth.

(4) Set up the stand and pick the buds. Polygonum multiflorum has many vines and is long. If it is planted in the ground, it should be planted in the second year. When the seedlings are about 10 centimeters high, a bamboo pole should be erected next to the plant to make the vines twine and grow upward. The base leaves should be removed to facilitate ventilation and light transmission. , promoting its production. If there are too many vines, some should be cut off, leaving only one branch per plant. Only the branches above 30 cm on the main vine should be kept, and the rest should be cut off. At the same time, the flower buds on the remaining branches (including the main vine) should be removed in time, with the exception of seed plots. To avoid consuming nutrients and affecting root growth. Generally, it needs to be pruned 5 to 7 times a year.
