Latest prices for Paris polyphylla seeds and how to grow them

Paris polyphylla, also known as Chinese Paris rhizome, seven-leaf lotus and iron lampstand, is a herbaceous plant of the genus Paris in the family Liliaceae. It grows in shady, damp spots under hillside forests and in thickets, and is distributed in China's Tibet, Yunnan, Sichuan, Guizhou and other places. Its rhizome is used as medicine and has the effects of clearing heat and detoxifying, reducing swelling and relieving pain, and calming the liver and stopping convulsions. Now let us take a look at the price of Paris polyphylla seeds and how to grow them!

How much does a jin of Paris polyphylla seeds cost?

The price of Paris polyphylla seeds is around 500 to 600 yuan per jin, but prices vary greatly depending on seed quality, purchase time, purchase market and other factors. Paris polyphylla likes warmth, moisture and shade, but it is also cold-resistant and drought-tolerant, and fears frost and direct sunlight. It prefers sandy soil and loam with a high content of organic matter and humus, and is especially suitable for planting by riversides, beside ravines and on shady hills. In production, seed planting is the main method, and direct sowing is usually best, but to save seeds and achieve dense planting and high yields, raising seedlings from seed and transplanting can also be used.

Sowing methods for Paris polyphylla

1. Direct sowing in the field: For direct sowing of Paris polyphylla in the field, in mid to late May after thorough rain, on the prepared seedbed surface, make small shallow pits 3 to 5 cm deep with a row spacing of 30 to 35 cm and a plant spacing of 20 to 25 cm. Make 4 rows on a narrow bed of 130 cm and 5 rows on a wide bed of 150 cm. Before sowing, soak the seeds in cold water for 24 hours, mix them with plant ash and sow. Put 2 to 3 seeds in each pit. After sowing, cover with 2 to 3 cm of fertile soil made of half fine manure and half fine soil. If the soil is dry, water promptly. Seedlings sprout and emerge in 7 to 10 days.

2. Raising seedlings and transplanting: For raising seedlings and transplanting Paris polyphylla, in early April choose a seedbed in dry land or vegetable garden land with a water source. Before digging the soil, it is best to disinfect the soil first, then repeatedly dig and turn the topsoil. After leveling and finely preparing the bed surface, open sowing furrows about 5 cm deep on the bed surface at a row spacing of 15 cm, sow in the furrows at a plant spacing of 5 cm, then cover with 3 cm of soil, cover with 2 cm of fine manure, water thoroughly and cover with plastic film. Seedlings can emerge in 5 to 7 days. After 1 month of seedling raising, transplant the small seedlings to the field according to the direct-sowing specifications.

Growing methods for Paris polyphylla

1. Thinning and filling in seedlings: In mid to late May, thin the seedlings in the direct-sown field, and at the same time check the pits and fill gaps. Before thinning, water first, then pry out the seedlings with a wooden stick. When filling in seedlings, water with settled-root water, make full use of small seedlings, and ensure a full stand and sufficient density.

2. Cultivation and weeding: The aboveground part of Paris polyphylla grows weakly, so special attention should be paid to loosening the soil and weeding. After the seedlings are uniform or after transplanting, weed and loosen the soil promptly. Hoe frequently and shallowly to avoid damaging the roots and affecting growth. Usually cover the bed surface with grass to retain moisture.

3. Reasonable fertilization: The base fertilizer for Paris polyphylla accounts for 70 to 80% of the total fertilizer amount, and later topdressing can only account for about 20% of the total fertilizer amount. After the seedlings emerge each year, apply human manure water once as topdressing. Do not use or use little chemical fertilizer, and the use of chemical nitrogen fertilizer is prohibited.

4. Watering and drainage: Paris polyphylla likes a shady and damp environment, and the bed surface and soil layer should be kept moist. In the dry season, water promptly, and spray water at intervals at ordinary times. In the rainy season, dredge ditches and drain promptly to prevent water accumulation in the field from inducing disease.

5. Cutting off flower stems: When growing Paris polyphylla, in order to reduce nutrient consumption and concentrate nutrients for the growth of underground tubers, when flower stems appear in May to June, cut off all flower stems promptly except those kept for seed, so as to increase yield.

6. Shade management: Throughout the whole growth period, Paris polyphylla prefers 40 to 50% light transmittance. After emergence and transplanting, shade measures should be taken. Where conditions permit, shade nets are best; where conditions do not permit, inserting branches for shade can be used.

Pest and disease control for Paris polyphylla

1. Damping-off:

[Harm] This is a seedling-stage disease. It occurs severely in April to May when temperatures are low and rain is frequent. In the early stage of the disease, yellow-brown water-soaked lesions appear on the base of the seedling stem and spread around the base, causing the seedlings to wilt. In severe cases, patches of seedlings wither and fall over.

[Control] Strengthen field management, disinfect the soil, pull out diseased seedlings after onset, disinfect the seedbed with chemicals and spray with zineb solution.

2. Sclerotinia disease

[Harm] It occurs in May each year when there is much rain and high humidity, damaging the base. Soft rot appears first, then white filamentous matter appears on the diseased part, after which dark brown granular sclerotia of the pathogen appear around the diseased part, and finally the whole plant withers and falls over.

[Control] Clean ditches and drain promptly to reduce field humidity. Pull out diseased plants promptly and spread lime at the center of infection. Spray with the pesticide thiophanate or validamycin 2 to 3 times in succession; in severe cases, spray with chlorothalonil.

3. Black spot

[Harm] The disease starts from the leaf tip or leaf base, producing round or nearly round lesions. Sometimes the disease spreads to the flower axis, causing leaf blight and stem blight.

[Control] Pay attention to drainage and reducing moisture, lower air humidity, and reduce disease incidence. In the early stage of the disease, spray 5% xiaodunqing aqueous solution or 50% thiophanate-methyl suspension concentrate.

4. Stem rot

[Harm] It mostly occurs during the seedbed stage, and is more severe during the field stage in high temperature and rainy periods. First, yellow-brown lesions appear at the stem base. After the lesions expand, the leaf tips lose water and droop. In severe cases, the stem base becomes wet and rotted and the seedlings fall over.

[Control] Before transplanting, spray the seedbed with 50% carbendazim wettable powder. In the early stage of the disease, drench the pits with 95% dexon wettable powder, once every 10 days, for 2 to 3 times in succession.

5. Scarab beetles

[Harm] Adults damage leaves, while larvae bite the rhizomes, affecting plant growth.

[Control] At night, use torches to lure and kill adults, and spray fresh vegetable leaves with trichlorfon and place them on the bed surface to lure and kill larvae.
