How do you grow Paris polyphylla so it thrives?

Paris polyphylla is a herbaceous plant in the genus Paris, also sometimes called Chongtai grass or Jinxian Chonglou. In many places it is also commonly known as Tu Sanqi and Qiye Lian. In China, the main growing areas are Taiwan, China, Guizhou, Yunnan, Sichuan, Xizang and other places. It has effects such as clearing heat and detoxifying, relieving pain, and reducing swelling. So how is Paris polyphylla grown? Let's explore this together below.

1. Site selection and land preparation

Paris polyphylla has the characteristics of liking warmth, liking moisture, liking shade, tolerating cold, resisting cold, fearing strong light, and fearing frost. Wild Paris polyphylla generally grows in relatively dark and damp areas under hillside forests and in shrub forests. So the planting site is generally chosen as sandy soil or loam that is dry, rich in organic matter, close to a river, and facing away from the sun. Before planting, prepare the land, spread sufficient decomposed farmyard manure, mix in an appropriate amount of high-efficiency compound fertilizer, and stir evenly. Then, according to the conditions of the planting site, open furrows in the prepared land and make beds, with the beds 1 m wide and 20 cm high, and level the bed surface.

2. Building a shade shed

Because Paris polyphylla is a plant that likes shade and fears sunlight, and likes slanted or diffused light, we need to build a shade shed before planting. If the planting site is chosen under a forest, then there is no need for the trouble of a large shed. But for many large-scale plantings of Paris polyphylla, there is not that much woodland available for planting, so we must build a shade shed in advance. The height of the shade shed is generally about 1.5 m. Materials that provide diffused light can be used to build above the shed, and branches can also be laid on top, leaving certain gaps for light.

3. Propagation methods

There are two methods of propagating Paris polyphylla, namely seed propagation and rhizome propagation, among which seed propagation is the most commonly used propagation method. Seed propagation is generally carried out by sowing in May each year. When sowing, dig holes in the field at a row spacing of 30 to 35 cm and a plant spacing of 20 to 25 cm, then sow 3 to 4 seeds in each hole and cover with soil. Rhizome propagation, on the other hand, is carried out by sowing in April each year and transplanting in May.

4. Field management

After the seedlings emerge, thin and fill in the seedlings in time to ensure a full stand in the field. Next, carry out appropriate cultivating and weeding, especially when there is more rainfall, so as to avoid soil compaction and affect the normal growth of the plants. At ordinary times, we can cover the bed surface with a layer of rice straw, which can play a role in heat preservation and moisture retention. Throughout its entire growth period, generally only three fertilizations are needed, mainly with decomposed organic fertilizer, and foliar fertilizer should be appropriately applied as a top dressing. It is best not to use chemical fertilizer, so as not to affect its yield and quality. In order to reduce nutrient consumption, we should appropriately cut off the ovaries of some flower scapes, which can increase the yield of Paris polyphylla.

5. Pest and disease control

Judging from the current planting situation, Paris polyphylla actually has no particular pests or diseases. However, when encountering low-temperature and rainy weather or high-temperature and high-humidity weather, the plants are also very prone to disease. So what we need to do is strengthen field management, pay attention to drainage, ventilation, and so on. During the initial stage of pests and diseases, confirm the condition and then apply the appropriate treatment.
