How many seedlings are needed to plant one mu of Paris polyphylla

SummaryPlanting one mu of Paris polyphylla requires about 15,000-17,000 seedlings. Choose a suitable seedbed, deeply plow the soil and disinfect it, then open sowing furrows about 5cm deep, place the seeds at a spacing of about 5cm, then cover with about 3cm of soil, and then cover with about 2cm of fine manure. After watering thoroughly, cover with film, and seedlings will emerge in about 7 days. Transplant after about 1 month of seedling cultivation.

I. Sowing Methods

1. Direct seeding

Paris polyphylla is generally sown after thorough rain in early to mid-January. With a row spacing of about 30-35cm and a plant spacing of about 20-25cm, dig small shallow pits about 3-5cm deep. Dig 4 rows in a 130cm furrow, and one row in a 150cm furrow.

Choose treated seeds, mix with plant ash and sow. Sow about 2-3 seeds per pit, then cover with soil and fertilize. Water immediately after the soil dries, and they will germinate and emerge in about 7-10 days.

2. Seedling raising and transplanting

First choose a suitable seedbed. Before turning the soil, disinfect it, then level and finely break up the soil and open sowing furrows about 5cm deep.

Place the seeds at a spacing of about 5cm, then cover with about 3cm of soil, cover with about 2cm of fine manure, water thoroughly and then cover with film. Seedlings will emerge in about 7 days. Transplant after about 1 month of seedling cultivation. About 15,000-17,000 plants can be planted per mu.

II. Planting Management Methods and Precautions

1. Choosing soil

Paris polyphylla has low requirements for soil and climate. Gray bubble soil and humus soil are preferred. You can choose shady flat land with shorter sunshine, or night-damp areas with strong water retention and relatively loose texture.

2. Land preparation and fertilizing

Because the root system of Paris polyphylla is relatively shallow, it needs to be prepared into furrows 120-150cm wide. Apply about 3,000-5,000 kg of forest humus fertilizer or farmyard manure per mu, then carry out shallow plowing to mix soil and fertilizer evenly. After breaking up the soil finely and raking it level, you can sow.

3. Thinning and filling in seedlings

Thinning is generally carried out in mid-to-late May. Before thinning, be sure to water first. Use a wooden pry to lift the seedlings. When filling in seedlings, water to settle the roots. To ensure a full stand, be sure to make good use of small seedlings.

4. Cultivation and weeding

From the end of May to early June, there is more rain and the soil easily becomes compacted. Be sure to drain water and prevent waterlogging in time. According to the growth of Paris polyphylla, carry out cultivation and weeding regularly, and loosen the soil shallowly.

5. Proper shading

Because Paris polyphylla prefers shade and avoids strong light, light exposure during growth is preferably 40-50%. Therefore, after emergence and transplanting, proper shading is needed. You can use shade netting, or insert branches beside them for shade.

6. Reasonable topdressing

Paris polyphylla generally grows relatively fast from mid-to-late June to August. Apply sufficient fertilizer in early June, about 2,000-3,000 kg of farmyard manure per mu, mixed with about 20-30 kg of calcium superphosphate and applied together.

7. Timely harvesting

Paris polyphylla is harvested from November-December to before sprouting the following spring. The tubers generally grow in the surface soil layer, making harvesting convenient. Try to keep the tubers intact. After digging, wash them clean, slice them and dry them in the sun.
