Planting technology and cultivation management of Paris polyphylla

Paris polyphylla is a common medicinal plant found in valleys, stream banks or under shady broad-leaved forests. It is well known for its numerous medicinal properties and is widely used in traditional medicine. As the understanding of the medicinal value of Paris polyphylla deepens, many regions have begun to try artificial cultivation to meet the market demand for this medicinal material. Below we will learn about the planting techniques and cultivation management of Fritillaria cirrhosa.

1. Site selection and land preparation

Growth environment: Paris polyphylla prefers an environment with an altitude of 500 to 3000 meters and a mild and humid climate. It requires fertile humus soil or acidic sandy loam, and avoids plots with poor drainage or heavy soil.

Land preparation: Select a plot with good shade and convenient irrigation, remove weeds and stones, apply 60.0-67.5 tons/hectare of decomposed farmyard manure as base fertilizer, deep plow the land about 25 cm, level it, dig trenches and make ridges with a width of about 1.2 meters, and ensure smooth drainage.

2. Breeding Methods

1. Seed propagation

The seeds of Paris polyphylla mature in October and should not be air-dried. They need to be sown immediately after harvesting or stored in sand. Use stratification synergistic gibberellin treatment or sand storage method to improve germination rate, pay attention to the "secondary dormancy" characteristics of seeds, and promote germination through alternating high and low temperature treatments.

2. Propagation by cutting off the rhizomes

It is mainly propagated through rhizomes. Choose healthy and disease-free rhizomes, cut them into sections, treat the incisions with wood ash or disinfectant, and cultivate them directly or grow seedlings first and then transplant them.

3. Cultivation Technology

Transplanting time: usually in winter, when the rhizomes are dormant, which is conducive to root growth.

Transplanting standards: 2 years after the seedlings emerge, transplant them according to the plant spacing of 15 cm × 20 cm, water them thoroughly to establish roots, and cover them with straw or pine needles to keep them warm and moist.

4. Field Management

Intertillage and weeding: Keep the soil loose and be careful not to damage the plants when weeding.

Shade: Build a shade shed or use the natural environment for shade, and control the shading rate between 60% and 70%.

Top dressing: Mainly use potassium sulfate, superphosphate and multi-component fertilizer , avoid using high-nitrogen fertilizers.

Water management: Keep the soil moist, water during droughts, and pay attention to drainage during rainy seasons.

Fruit picking: The fruits of plants that are not left for seeds should be picked promptly to concentrate nutrients on the rhizomes.

Pest and disease control: Use integrated agricultural measures and chemical methods to prevent and control pests, maintain field hygiene, and rotate crops rationally.

5. Harvesting and Processing

Harvesting time: Seed-propagated seedlings are harvested in the 6th year after transplanting, and rhizome-propagated seedlings are harvested in the 3rd year.

Processing method: After harvesting, cut off the stems and leaves, dig up the rhizomes to avoid damage, cut the rhizomes into thin slices, dry in the shade or in the oven, and then store or sell.

The above is the planting technology and cultivation management of Paris polyphylla. By referring to and learning from the actual situation, you can effectively improve the yield and quality of Paris polyphylla and meet market demand.
