How to plant Polygonum multiflorum

1. When planting Polygonum multiflorum, we must first do a good job in seed selection. Good seeds should be selected. The seeds of Polygonum multiflorum changed from white to brown, and matured when the interior turned black, which needs to be harvested in time. After the seeds are harvested and dried in the sun, they can be packed in gunny bags or sandcloth bags and stored in a ventilated and dry place. do not cover the seeds with plastic bags.

2. Then choose a suitable place for cultivation. In order to grow Polygonum multiflorum, it is better to choose sandy soil with deep soil layer, loose and fertile soil, convenient water source and energy drainage. Deep ploughing of 30cm in winter, after a winter weathering, the following spring soil preparation, wide 100cm, high 20cm of the border, requiring each square meter of high-quality farm fertilizer 10kg, must be evenly spread, and then shallowly turned into the soil.

3. Then sow it, and the best time is in March of each year. In the whole nursery land border, open a shallow ditch according to the row spacing 10-15cm, then spread the seeds evenly into the ditch, cover a layer of soil about 1.5cm thick, cover with grass, and then drench with water. The general sowing rate is 46.6g per square meter. After sowing, Polygonum multiflorum should be gently watered with a spray can every day after 10:00 or 5pm, and then watered for 3 days after emergence. At this time, the cover grass should be removed in time, and attention should be paid to pulling out weeds while keeping the border soil wet. After 20 days of emergence, the seedlings should be replenished and the seedlings should be fixed by 4-5cm according to the distance between plants. In the meantime, we must pay more attention.

4. Two months after the seedlings were unearthed, the seedlings could be sprayed with 100kg water plus 0.2-0.3kg compound fertilizer or urea, once every 15 days. 0.5% can be used in the middle and later stages. 1% concentration compound fertilizer or urea can be sprayed. If there are insect pests, you can kill them manually, or control them with a spray of 2000 times the enemy's killing rate. The disease can be prevented with a Bordeaux solution of 200 times that of 1 Vera and a Bordeaux solution of 200 times. In severe cases, it can be sprayed with 25% carbendazim 500 Mel 800 times solution. This will ensure its growth.

In fact, the time from planting to harvest of Polygonum multiflorum is not very long. When planting, we must do a good job in seed selection, and then plant it in a timely manner. After planting, we still need to strengthen management, fertilizer and water needs to be done well, so as to ensure that its growth will be better.
