What are the cultivation methods for Paris polyphylla?
Paris polyphylla is a plant in the genus Paris of the family Liliaceae (now Melanthiaceae). It is a precious traditional Chinese medicine and also an ornamental plant, distributed in Southeast Asia and the southwestern region of China. So, what cultivation methods are there for Paris polyphylla? Let's find out together!
1. Site selection and land preparation
Paris polyphylla has the characteristics of preferring warmth, preferring moisture, preferring shade, tolerating cold, resisting cold, fearing strong light, and fearing frost. Generally, wild Paris polyphylla grows in relatively dark and damp areas under hillside forests and in shrub forests, so the planting site is generally chosen in places rich in organic matter and close to rivers. The soil is best sand or loam. 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 size of the planting site, dig furrows and make beds in the prepared land, with beds 1 m wide and 20 cm high, and level the bed surface.
2. Build a shed for shade
Since Paris polyphylla is a plant that prefers shade and fears sunlight, and prefers oblique or scattered 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 much of the large-area cultivation of Paris polyphylla, there is not that much forest land available for planting, so we must build the shade shed in advance. The height of the shade shed is generally about 1.5 m. Above the shed, materials that provide scattered light can be used for construction, and branches can also be laid, leaving certain gaps for light.
3. Propagation methods
There are two propagation methods for Paris polyphylla, namely seed propagation and rhizome propagation. Among them, 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 uniform seedlings in the field. Next, carry out appropriate intertillage and weeding, especially when there is more rainfall, so as to avoid soil compaction and affect the normal growth of the plants. Usually, a layer of rice straw can be spread over the bed surface, which can play a role in heat preservation and moisture retention. During its entire growth period, generally only three fertilizations are needed, mainly with decomposed organic fertilizer, and appropriate foliar fertilizer should be applied as a top dressing. It is best not to use chemical fertilizers, 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 stalks, which can increase the yield of Paris polyphylla.
5. Pest and disease control
Judging from the current cultivation situation of Paris polyphylla, it actually does not have many pests and diseases, but under weather with low temperature and much rain or high temperature and high humidity, the plants are also very prone to disease. So what we need to do is strengthen field management, pay attention to drainage and ventilation, and during the early stage of pests and diseases, confirm the condition and then apply the right treatment.
