A Detailed Guide to Paris polyphylla Planting Techniques and Management Methods

Paris polyphylla, also known as Chonglou, is a medicinal herb. It is commonly used for boils and carbuncles, sore throat, snake and insect bites, bruises and injuries, and convulsions. So, what are the planting techniques for Paris polyphylla?

1. Planting time

Paris polyphylla is generally planted in late April. In a well-prepared field, make beds 1.3 m wide, then open horizontal furrows on the beds, with a furrow spacing of 22-26 cm and a furrow depth of 7-10 cm, and plant 1 tuber every 7-10 cm, with the bud pointing upward.

2. Apply sufficient base fertilizer

When planting Paris polyphylla, apply 2000-3000 kg of barnyard manure or compost per mu. After applying the manure, cover with soil level with the bed surface, with a soil cover depth of 4-5 cm, press lightly, and use 20-25 kg of small tubers per mu.

3. Field management

Shading requirements: Chonglou likes shade. If the shade coverage of the plot is insufficient, build a trellis with wire and cement posts, and cover the top of the trellis with plastic sheeting or other methods to create a shaded and moist environment for the growth of Chonglou.

The growth period of Paris polyphylla is very short, and it emerges relatively late, generally emerging around June. In mid-June, carry out intertillage, weeding, and fertilization, and in early August carry out intertillage, weeding, and topdressing once again.

4. Harvesting and seed reservation

Paris polyphylla is dug up in late September. Separate the large and small ones. Clean the large ones of soil and fibrous roots, dry them in the sun, and use them for medicine. Keep the small tubers as seed tubers. Store the small tubers in a kiln, stacking them in layers with dry fine sand and mud, and store them through the winter. The kiln temperature should be kept at 2-5°C.

Paris polyphylla grows on wasteland, hillsides, and beside ditches. It can tolerate cold, shade, and drought, and likes a cool and fairly shady and moist environment. It is not strict about the previous crop, and grows well in grain fields and vegetable plots. Cultivation under forest or intercropping in vineyards and fruit tree plots can both achieve high yields.
