How much do Paris polyphylla seeds cost? Detailed planting guide

Paris polyphylla, also known as Huachonglou, Qiyelian, Tiedengtai and so on, is a herbaceous plant of the genus Paris in the Liliaceae family. It grows under forest on mountain slopes and in damp shaded areas of 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. Let's take a look below 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 500-600 yuan per jin, but prices vary considerably depending on seed quality, purchase time, market and so on. Paris polyphylla likes warmth, moisture and shade, but is also cold-resistant and drought-tolerant, and fears frost and direct sunlight. It prefers sandy soil and loam with high organic matter and humus content, and is especially suited to planting by riversides, ravine edges and shaded hillsides. In production, seed planting is the main method, and direct sowing is usually best, but to save seeds and achieve high yields through close planting, seedling raising 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, after thorough rain in mid to late May, on the prepared ridge surface, make small shallow holes 3-5 cm deep with a row spacing of 30-35 cm and a plant spacing of 20-25 cm. A narrow ridge of 130 cm takes 4 rows, and a wide ridge of 150 cm takes 5 rows. Before sowing, soak the seeds in cold water for 24 hours, mix with plant ash and sow, placing 2-3 seeds per hole. After sowing, cover with 2-3 cm of fertile soil made of half fine manure and half fine soil. Water promptly if the soil is dry, and seedlings emerge in 7-10 days.

2. Seedling raising and transplanting: For raising seedlings and transplanting Paris polyphylla, in early April select 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 ridge surface, open sowing furrows about 5 cm deep on the ridge 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 and 2 cm of fine manure, water thoroughly and cover with plastic film. Seedlings emerge in 5-7 days. One month after raising seedlings, transplant the young seedlings into the field according to the direct sowing specifications.

Planting methods for Paris polyphylla

1. Thinning and replanting: In mid to late May, thin the directly sown field of Paris polyphylla, and at the same time check the holes and fill gaps. Before thinning, water first, and use a wooden stick to pry out the seedlings. When replanting, water with rooting water, make full use of the small seedlings, and ensure full stands and sufficient density.

2. Cultivation and weeding: The above-ground part of Paris polyphylla grows weakly, so special attention must be paid to loosening the soil and weeding. Weed and loosen the soil promptly once the seedlings are uniform or after transplanting. Hoe frequently and shallowly to avoid damaging the roots and affecting growth. Normally cover the ridge surface with grass to retain moisture.

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

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

5. Pruning flower stems: When planting Paris polyphylla, to reduce nutrient consumption and concentrate nutrients on the growth of the underground tubers, when flower stems appear in May-June, promptly prune all flower stems except those kept for seed, so as to increase yield.

6. Shade management: Throughout the entire growth period of Paris polyphylla, a light transmittance of 40-50% is best. 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] It is a disease of the seedling stage, and occurs severely in April-May when temperatures are low and rain is frequent. In the early stage of the disease, yellow-brown water-soaked lesions appear at the base of the seedling stem and spread around the base, causing the seedlings to wither, and in severe cases patches of seedlings die and fall over.

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

2. Sclerotinia rot

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

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

3. Black spot

[Harm] The disease starts from the leaf tip or leaf base and produces 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% junduqing 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 conditions. First, yellow-brown lesions appear at the stem base. After the lesions expand, the leaf tip loses water and droops, and in severe cases the stem base becomes wet and rots and the plant falls over.

[Control] Before transplanting, spray the seedbed with 50% carbendazim wettable powder. In the early stage of the disease, drench the holes with 95% fenaminosulf wettable powder, once every 10 days, for 2-3 consecutive drenches.

5. Scarab beetles

[Harm] Adults harm leaves, and larvae bite and eat rhizomes, affecting plant growth.

[Control] At night, use torches to trap and kill adults, and use fresh vegetable leaves sprayed with trichlorfon placed on the ridge surface to trap and kill larvae.
