Detailed Introduction to Paris polyphylla Seed Prices and Planting Methods

Paris polyphylla, also known as Chinese Paris, seven-leaf lotus, iron lampstand, etc., is Yunnan Paris polyphylla or Paris polyphylla var. chinensis of the genus Paris in the Liliaceae family. It is produced in Yunnan, Guizhou, Sichuan, Guangdong, Guangxi, Jiangxi, Fujian, Shaanxi and other places. As medicine it has the effects of clearing heat and detoxifying, reducing swelling and relieving pain, and cooling the liver and calming fright. Now let us take a look at Paris polyphylla seed prices and planting methods!

How much does a jin of Paris polyphylla seeds cost?

The price of Paris polyphylla seeds is about 200-300 yuan per jin, but it varies depending on seed quality, variety, place of origin and market. Paris polyphylla often grows in shady and humid places under mountain forests or in roadside grass. In cultivation it is mostly propagated by seeds and can be directly sown, but to save seeds and achieve high yield through close planting, seed seedling raising and transplanting can also be used. The growth cycle is very long. From seedling raising to transplanting takes three years. After three years it is transplanted, and after transplanting it grows for 5 years. Yunnan Paris polyphylla can reach a yield of 1500 kg of fresh product per mu, and Chinese Paris can reach about 1000 kg.

Sowing methods for Paris polyphylla

1. Direct seed sowing: In early to mid-January after thorough rain, on the prepared seedbed surface, make small shallow ponds 3-5 cm deep with a row spacing of 30-35 cm and a plant spacing of 20-25 cm. For a narrow bed of 130 cm, make 4 rows; for a wide bed of 150 cm, make 1 row. Before sowing, soak the seeds in cold water for 24 hours, mix with plant ash and sow. Put 2-3 seeds in each pond, then cover with 2-3 cm of fertile soil made of half fine manure and half fine soil. If the soil is dry, water promptly. Seedlings emerge in 7-10 days.

2. Seedling raising and transplanting: In early April, select a seedbed in dry land with a water pool or in vegetable garden land. Before digging the soil, disinfect it with quintozene. Then level and finely prepare the bed surface, open sowing furrows about 5 cm deep on the bed surface, place seeds 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 1-7 days. One month after seedling raising, transplant the small seedlings into the field according to the direct sowing specifications.

Planting methods for Paris polyphylla

1. Soil selection: Paris polyphylla does not have strict requirements for climate and soil type, but it is best to choose shady gentle slope land or flat land with shorter sunlight exposure, and to plant in night-moist soil, gray bubble soil, or humus soil that is loose in texture and relatively strong in both water retention and water permeability.

2. Land preparation and fertilization: The root system of Paris polyphylla is not deep. After general land preparation, form beds 120-150 cm wide. Apply 3000-5000 kg of farmyard manure or forest humus fertilizer per mu, then dig ditches and cover with fertilizer, and shallow hoe once so that the fertile soil in the plow layer is uniform. Level and finely prepare it before planting.

3. Thinning and replanting: For Paris polyphylla planting, thin the directly sown land in mid to late May, and at the same time check the ponds and fill gaps. Before thinning, water first, take seedlings with a wooden pry, and when replanting, water to settle the roots. Make full use of small seedlings to ensure a full stand and sufficient density.

4. Cultivation and weeding: The aboveground part of Paris polyphylla grows weakly, so special attention should be paid to loosening the soil and weeding. Generally from late May to early June there is a lot of heavy rain, and the soil easily becomes compacted, so drainage and waterlogging prevention should be done promptly. Cultivate frequently and loosen the soil shallowly, and remove weeds at any time.

5. Timely shading: Paris polyphylla likes shade and fears strong light. Throughout the whole growth period, a light transmittance of 40-50% is best. Therefore, after emergence and transplanting, shading measures should be taken. Where conditions permit, shade nets are best used; where conditions do not permit, inserting branches for shade can be used.

6. Topdressing and earthing up: Paris polyphylla has the growth pattern that when it flowers above, the tuber below expands. Generally it grows fastest from mid to late June to August. A heavy topdressing must be applied in early June, using 2000-3000 kg of cattle and sheep barn manure or farmyard manure plus 20-30 kg of ordinary calcium superphosphate per mu.

7. Timely harvest: Paris polyphylla can be harvested in autumn before and after the stems fall, that is, from November to December until before sprouting the following spring. The tubers mostly grow in the surface soil layer and are easy to dig, but care should still be taken to keep the tubers intact. After digging out, wash them clean, slice them fresh, and dry them in the sun.

Pest and disease control of Paris polyphylla

1. Black spot disease

[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 the incidence. In the early stage of the disease, spray 1% chlorothalonil aqueous solution at 300-500 times dilution, or 50% thiophanate-methyl suspension concentrate at 1500-2000 times dilution.

2. Stem rot

[Harm] It mostly occurs during the seedbed stage, and is more serious in the field stage during 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 collapse.

[Control] Rotate with gramineous crops for more than 3 years. Before transplanting, spray the seedbed with 50% carbendazim wettable powder at 1000 times dilution. In the early stage of disease in the field, drench the ponds with 95% dexon wettable powder at 1000 times dilution.

3. Scarab beetles

[Harm] The adults (fried bean insects) damage leaves, and the larvae (white soil grubs) bite the rhizomes, affecting the growth of Paris polyphylla.

[Control] At night, use torches to trap and kill adults. Spray fresh vegetable leaves with trichlorfon and place them on the bed surface to trap and kill larvae. When preparing land and making beds, broadcast 135-2 kg of 5% phoxim granules per mu.
