Now let us take a look at whether growing Paris polyphylla can make money!
Can you make money growing Paris polyphylla?
Paris polyphylla has a relatively long growth cycle, wild resources are basically on the verge of depletion, and current 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, with the withdrawal of inferior products from the market, the fundamental supply-demand contradiction of Paris polyphylla cannot be changed in the next few years and will only intensify. Therefore, in the coming 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 not blindly follow the trend.
Propagation methods of Paris polyphylla
1. Rhizome propagation: In autumn and winter, dig out robust rhizomes free of pests and diseases and store them in sand in a cool, dry place. Take them out in early to mid-April of the following year. According to the characteristics of residual buds and bud scars on stems that have sprouting 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 a seedbed like sowing seeds, and cover with plastic film. After 11-20 days, when roots and buds sprout and grow from the cut roots, transplant them to the field in early May according to the direct seeding specifications.
2. Seed propagation: Paris polyphylla seed propagation can use direct seeding, but to save seeds and achieve high yield through close planting, seed seedling 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 3-5 cm deep with a row spacing of 30-35 cm and a plant spacing of 20-25 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. Put 2-3 seeds in each hole. After sowing, 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 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 1-7 days. After 1 month of raising seedlings, transplant the small seedlings to the field according to the direct seeding 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 gently sloping shaded land or flat land with shorter sunlight exposure, and soil that is loose in texture and relatively strong in both water retention and water permeability, such as night-damp soil, gray bubble soil, and humus soil.
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 rake the ditches and cover with fertilizer, and shallow hoe once so that the fertile soil in the plow layer is uniform. Level and finely prepare the soil and wait for planting.
3. Thinning and replanting: In mid to late May, thin the seedlings in directly sown land, and at the same time check the holes and fill gaps. Water before thinning, take out seedlings with a wooden pry, and water with rooting water when replanting, making full use of small seedlings to ensure full stands 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 hardens, so drainage and waterlogging prevention should be done promptly. Cultivate frequently, 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 a growth pattern in which flowers form above while the tuber expands below. It generally 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 stable manure or farmyard manure plus 20-30 kg of ordinary calcium superphosphate per mu.
7. Timely harvesting: Paris polyphylla can be harvested in autumn before and after the stems fall, that is, from November to December, or before sprouting in the following spring. The tubers mostly grow in the topsoil and are easy to dig, but attention should still be paid to keeping the tubers intact. After digging out, wash them clean, slice them while fresh, and dry them in the sun.
