A Detailed Guide to the Cultivation Techniques and Planting Methods of Paederia scandens
Although Paederia scandens has an unpleasant name, it is a very well-known medicinal herb and was once a common traditional Chinese medicinal material. Paederia scandens has extremely strong growth ability. Once planted, it can be harvested continuously for several years, and the main part used for medicine is the above-ground portion of Paederia scandens. Paederia scandens has extensive wild and cultivated areas in southern China, so how should Paederia scandens be cultivated? Below, the editor brings you the cultivation techniques for Paederia scandens. Let's take a look!
1. Sowing and seedling raising
As just mentioned, Paederia scandens has extremely strong growth ability, so it does not have great requirements for soil; it is enough to ensure that the soil is fertile and free of pests and diseases. Paederia scandens matures around October each year. When mature, collect plump and juicy seeds and screen out the damaged and shriveled ones. Then wrap the healthy seeds in wet sand and wait until the following spring to sow. Before sowing, first dig planting holes in the soil, and place 8-10 seeds in each planting hole. After sowing, cover with a layer of fine soil and plant ash, and water appropriately. Usually, they will germinate and emerge in 7-10 days.
2. Water management
After Paederia scandens is sown and emerges, water management should be strengthened, but it mainly depends on the weather. When there is a lot of rainfall, not only should watering be avoided, but drainage work should also be done well. If there is a long-term drought, then it needs to be watered in time. Water management is the key to ensuring the healthy growth of Paederia scandens. But it is also one of the main causes of the death of Paederia scandens, because many friends cannot control the amount of watering well when planting. Too much watering or failure to drain in time leads to severe waterlogging in the field, causing the roots of Paederia scandens to rot.
3. Timely topdressing
The growth of Paederia scandens has certain nutritional needs, especially in spring and summer, which are the two seasons when Paederia scandens grows fastest. The demand for nutrients will further increase, so topdressing for Paederia scandens should be done well in these two seasons. Control the frequency of topdressing according to the specific growth situation of Paederia scandens, usually once a month, with farmyard manure as the main fertilizer, combined with a small amount of compound fertilizer, to meet the nutritional requirements of Paederia scandens. When Paederia scandens grows to about 32 cm, apply a heavy dressing again. And before winter begins, sufficient fertilizer also needs to be applied to help the Paederia scandens plants overwinter.
4. Disease control
The disease resistance of Paederia scandens is also very strong. Normally, the incidence of pests and diseases is very high. But this is mainly premised on proper management by growers. If management is poor, Paederia scandens will still be attacked by aphids. Aphids will bore into and feed on the rhizomes of Paederia scandens, causing nutrient loss and hindering growth, and may also trigger other diseases. In severe cases, it can lead to plant death. If few aphids are found, manual capture can be used. But if the number is large, then pesticides such as omethoate solution need to be sprayed for control.
The above is a brief introduction to the cultivation techniques of Paederia scandens. The management of Paederia scandens is very simple; it is enough to regularly weed and control the temperature well. Next is to improve field ventilation and light transmission, promote plant growth, and prevent aphid infestation that threatens plant growth. That is all for today's introduction.
