How to Plant Paris polyphylla? A Detailed Explanation of the Key Cultivation Techniques
Paris polyphylla is presumably no stranger to many people; it is a relatively common traditional Chinese medicinal herb in daily life. The appearance of Paris polyphylla is also generally similar to that of ordinary wild grass, and it likes to grow in warm places. Paris polyphylla has high value, so nowadays there are also many people cultivating it. But before planting it, what everyone is surely most concerned about is still its cultivation techniques!
How to Plant Paris polyphylla
1. Sowing the seeds. The planting time for Paris polyphylla seeds is generally in January each year. 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 1 row on a wide bed of 150 cm. Before sowing, soak the seeds in cold water for 24 hours, then mix with plant ash and sow; put 2-3 seeds in each hole, then cover with 2-3 cm of fertile soil made of half fine manure and half fine soil; if the soil is found to be dry after emergence, water it in time.
2. Seedling raising and transplanting: The time for raising seedlings and transplanting Paris polyphylla is generally in April each year, and a dry place with a water source should be chosen. Before digging the soil, it is best to disinfect the soil by mixing 40% quintozene at 5-10 grams per square meter with fine soil and broadcasting it. After leveling and finely raking the seedbed surface, open sowing furrows about 5 cm deep on the seedbed 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, cover with 2 cm of fine manure, water thoroughly and cover with plastic film; seedlings can emerge in 5-7 days. After one month of seedling raising, transplant according to the specified size.
Paris polyphylla Cultivation Techniques
1. Variety selection: It is best to choose the seeds of Paris polyphylla var. yunnanensis as the source for sowing.
2. Choose a suitable place. Paris polyphylla likes to grow in warm and rather shady places, so site selection is very important. But it also needs a certain amount of light, so when choosing a planting site, choose sloping land with short sunshine duration, and the soil is best loose humus soil. The root system of Paris polyphylla does not grow deep, so when preparing the land, only shallow plowing is needed; when preparing the land, apply sufficient base fertilizer and then make beds, generally with a bed width of 1.5 m and a height of about 30 cm, then mix the base fertilizer and soil together evenly, and finally level it and sow.
3. Sowing techniques. When sowing Paris polyphylla, a suitable time needs to be chosen. The sowing time is in May. Before sowing, first soak the seeds in clean water for one day, then take them out and mix with plant ash for disinfection before sowing. When sowing, make holes in the ground, generally 3-5 cm deep, with a hole spacing of 30-35 cm. Sow two or three seeds in each hole, cover with soil in time after sowing, and water according to the dry and wet condition of the soil; seedlings can emerge in about one week.
4. Thinning and replanting: In mid-to-late May each year, the planting site can be replanted. At the same time, check the holes and fill the gaps; before thinning, water first, pry out the seedlings with a wooden stick, and water with settled-root water when replanting. When replanting, be sure to make full use of small seedlings to ensure the density of small seedlings.
Pest and Disease Control of Paris polyphylla
1. Damping-off. This disease is relatively common. When controlling it, be sure to strengthen seedbed management and provide appropriate ventilation and light. When the disease is first seen, spray 65% chlorothalonil wettable powder at 600 times dilution, 60% mancozeb wettable powder at 500 times dilution, or 62.2% propamocarb aqueous solution at 600 times dilution, once every 6-10 days, for 2-3 treatments. Finally, it is also necessary to promptly remove some of the diseased soil nearby.
2. Scarab beetles. It is best to do this at night; torches can be used to trap and kill the adults. Spray fresh vegetable leaves with trichlorfon and place them on the seedbed surface to trap and kill the larvae. When preparing the land and making beds, broadcast 5% phoxim granules at 1.5-2 kg per mu, or 3X carbofuran granules at 2.3 kg. When controlling, the dosage must be well controlled.
The planting method of Paris polyphylla is actually not difficult. When planting, first choose a good variety, then plant at the appropriate time. Field management after planting also needs to be strengthened. Paris polyphylla is also very susceptible to pests and diseases, so this work must also be done well, so that it can grow better.
