Can you make money growing Paris polyphylla? Profit analysis of Paris polyphylla cultivation
Paris polyphylla, also known as Dian Paris polyphylla, Dujiaolian, Hua Paris polyphylla, etc., is a perennial herbaceous plant of the genus Paris in the family Liliaceae. Its rhizome is used as medicine and has the effects of clearing heat and detoxifying, reducing swelling and relieving pain, and cooling the liver and calming fright. It is mainly produced in Yunnan, Guizhou, Sichuan and other provinces, and is now cultivated throughout the country. It has very high medicinal value and cultivation prospects. Let us take a look below at whether growing Paris polyphylla can make money!
Can you make money growing Paris polyphylla?
Paris polyphylla has a relatively long growth cycle, and wild resources are basically on the verge of running out. At present, market inventory is very weak. At the same time, the cost of cultivated Paris polyphylla remains high, it takes a long time, and distant water cannot quench present thirst. In addition, inferior products are being withdrawn from the market. Therefore, the fundamental supply-demand contradiction for Paris polyphylla cannot be changed in the next few years and will only intensify. Thus, in the next few years, the price of Paris polyphylla will still run at a high level. From these aspects, developing Paris polyphylla cultivation has very good prospects, but it must be adapted to local conditions, and one must never blindly follow the trend.
Propagation methods of Paris polyphylla
1. Rhizome propagation: In autumn and winter, dig up robust rhizomes free of pests and diseases and store them in sand in a cool, dry place. In early to mid-April of the following year, take them out. According to the characteristics of residual bud-bearing stems and bud scars with germination ability, cut them into small sections, ensuring each section has 1 bud scar. After cutting, dry them properly and mix with plant ash. Sow them in rows on the seedbed like sowing seeds, and cover with plastic film. After 11 to 20 days, after the cut roots sprout and grow roots and buds, transplant them to the field in early May according to the direct sowing specifications.
2. Seed propagation: Paris polyphylla seed propagation can use direct sowing, but to save seeds and achieve dense planting and high yield, seed seedling raising and transplanting can also be used.
① Direct seed sowing: In early to mid-January after thorough rain, on the prepared seedbed surface, make small shallow holes 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 make 1 row on a wide bed of 150 cm. Before sowing, soak the seeds in cold water for 24 hours, mix with plant ash, and sow. Place 2 to 3 seeds per hole. 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 it promptly. Seedlings emerge in 7 to 10 days.
② Seedling raising and transplanting: In early April, select a seedbed in dry land with water pools or in vegetable garden land. Before digging the soil, disinfect the soil 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 to 7 days. After 1 month of seedling raising, transplant the small seedlings to the field according to the direct sowing specifications.
Cultivation methods of Paris polyphylla
1. Soil selection: Paris polyphylla does not have strict requirements for climate and soil type, but it is best to choose shaded gentle slope land or flat land with relatively short sunlight exposure, and to plant it 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 to 150 cm wide. Apply 3000 to 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 cultivation, thin the directly sown field in mid to late May, and at the same time check the holes and fill gaps. Before thinning, water first, use a wooden pry to lift the seedlings, and when replanting, water to settle the roots. Make full use of small seedlings to ensure a full stand and sufficient density.
4. Intertillage 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 entire growth period, a light transmittance of 40 to 50% is best. Therefore, after emergence and transplanting, shading measures should be taken. Where conditions permit, it is best to use shade nets. Where conditions do not permit, the method of inserting branches for shade can be used.
6. Topdressing and earthing up: Paris polyphylla has the growth pattern that when it blooms aboveground, the tuber belowground expands. Generally, growth is fastest from mid to late June to August. Heavy topdressing must be applied in early June, using 2000 to 3000 kg of cattle and sheep barn manure or farmyard manure per mu plus 20 to 30 kg of calcium superphosphate.
7. Timely harvesting: Paris polyphylla can be harvested either around the time of aboveground withering in autumn, that is, from November to December, or before sprouting in the following spring. The tubers mostly grow in the surface soil layer and are easy to dig, but attention should still be paid to keeping the tubers intact. After digging them out, wash them clean, slice them while fresh, and dry them in the sun.
