How to manage the planting method and time of Polygonum multiflorum

Planting time: direct seeding from early March to early April, root propagation from February to March or August to September. Select seeds: select high-quality seeds free from diseases and insect pests. Land selection and land preparation: choose the sandy soil with loose and fertile soil and convenient water source, turn the soil about 30 cm deep in winter, and prepare the soil in the spring of the second year. Sowing at the right time: the sowing amount is 4-6g per square meter. Late management: water was watered every 2-3 days after emergence, and seedlings should be replenished 20 days after emergence.

First, planting time

1. We can choose to conduct direct seeding from early March to early April, according to the row spacing of 30-35cm, and then apply appropriate amount of human and animal manure water, then sow the seeds evenly into the ditch and cover the soil with 3cm. When the seedlings grow to 5cm, the suitable spacing is about 30cm.

2. Using tuber root propagation, you can choose to pick and dig Polygonum multiflorum tuber root from February to March or August to September every year, and then select small and medium-sized tuber roots, or the stem base of tuber roots to plant in loose, fertile and well-drained plots. After sowing, the root water needs to be watered once, and the normal management can be restored after emergence.

2. Suitable planting area

1. Polygonum multiflorum likes to grow under hillside forests, valley thickets and gully stone gaps, and is suitable for planting in southern Shaanxi, southern Gansu, East China, Central China, South China, Sichuan, Yunnan and Guizhou.

2. The root tuber of Polygonum multiflorum can be used as medicine, and it has the effect of nourishing blood and nourishing yin, moistening intestines and relieving defecation, dispelling wind and detoxification.

Third, select seeds

1. First of all, it is necessary to select high-quality, pest-free seeds. The seeds of Polygonum multiflorum change from white to brown, and when the interior changes to black, it is already ripe, so it needs to be harvested at this time.

2. After drying the harvested seeds, they can be packed in gunny bags or sandcloth bags. During this period, the seeds should be stored in a ventilated and dry place. Do not use plastic bags to store the seeds.

IV. Land selection and preparation

1. To choose suitable soil for planting, Polygonum multiflorum is suitable to choose sandy soil with deep soil layer, loose and fertile soil, convenient water source and drainage and irrigation.

2. After deeply turning the soil 30cm in winter, after winter weathering, the soil preparation will be carried out in the spring of the second year, with a width of 100cm and a height of 20cm. It is required that 10 kg of high quality farm manure should be applied per square meter, which can be evenly scattered on the border and then turned into the soil shallowly.

5. Sowing seeds at the right time

The main results are as follows: 1. The suitable sowing time of Polygonum multiflorum is from early March to early April, during which shallow trenches can be opened according to the row spacing of 10-15cm on the whole nursery land.

2. Sow the seeds evenly into the ditch, sprinkle about 1.5cm thick soil, and then cover with forage to soak the soil thoroughly. Generally, the sowing rate is 4-6 grams per square meter.

VI. Post-management

1. After sowing, Polygonum multiflorum should be watered with a spray can at 10:00 or 5pm every day. After emergence, it can be watered every 2-3 days.

2. At this time, the forage should be removed in time, and the weeds can be pulled out while keeping the border soil moist. 20 days after emergence, the seedlings need to be replenished, and the seedlings can be fixed according to the plant spacing of 4-5cm.
