How to Grow Paris polyphylla? A Detailed Guide to the Latest Cultivation Techniques

When it comes to Chonglou (Paris polyphylla), many people think of the Demon Lord Chonglou in Chinese Paladin, which is arguably a classic in TV dramas. However, the Chonglou I am talking about is not that Chonglou. Today I am going to talk about the medicinal herb Chonglou (Paris polyphylla), which is mainly used to treat boils and carbuncles, sore throat, snake and insect bites, bruises and injuries, and convulsions. So how is Chonglou grown? Let's learn about it together.

1. Site Selection and Land Preparation

The planting site for Chonglou is generally chosen on a shady plot with shade cover, convenient drainage and irrigation, rich organic matter, and loose soil, such as woodland or vegetable plots. Chonglou is a shallow-rooted plant that grows rather slowly, takes a long time to raise seedlings, and has high soil requirements. When preparing the land, clear stones and weeds from the field, break up the soil clods, and level the ground. Of course, another important point is that fertilization should be combined with land preparation, and the base fertilizer is mainly decomposed organic fertilizer.

2. Sowing and Raising Seedlings

Chonglou is generally sown and raised in January each year, and the seeds should be plump, free of pests and diseases, and not moldy. Then expose the seeds to the sun for two to three days, mix them with river sand to promote germination, and keep the river sand moist to ensure the seeds can breathe fully. Before sowing, disinfect the soil with carbendazim, and then sow. When sowing, generally open furrows and sow at a row spacing of 30 to 35 cm. Normally seedlings emerge in about a week, and during this period, keep the soil moist to promote emergence and the growth of the seedlings.

3. Scientific Transplanting

Generally, the seedling-raising period is about one month, which means transplanting can be done after one month. In some cases, however, you must wait three years before digging out the seedlings for transplanting. When transplanting, plants are usually set in the field at a row spacing of 30 cm and a plant spacing of 20 cm. After transplanting, if the planting site cannot provide shade, we also need to build a shade shed in advance. When transplanting seedlings, note that they should be planted with the soil attached, as this can increase the survival rate.

4. Field Management

We all know that Chonglou is generally planted in March or April, when there is a lot of rain, so after transplanting there is no need to water, but at this time we should pay attention to proper drainage. Dredge the field ditches in time to drain excess water out of the field, and if the weather is relatively dry, then water reasonably. Chonglou is generally cultivated and weeded from September to October, and doing it twice is usually enough. When cultivating, be careful not to plow deeply, so as not to damage the root system of Chonglou. Topdressing is needed two to three times each year, generally about 15 days after spring planting, then once in autumn, and finally in November or December in winter. Topdressing is mainly based on compound fertilizer, with each application around 30 grams.

5. Pest and Disease Control

The main diseases of Chonglou are root rot and leaf blight. Root rot mainly harms the root system of Chonglou, and the main cause of the disease is excessive water in the field, which causes the roots to rot and eventually kills the plant. Leaf blight mainly harms the leaves of Chonglou and is a fungal infectious disease. They can be controlled with carbendazim and Bordeaux mixture respectively. The main pests are cutworms and white grubs, which we can directly poison with deltamethrin emulsifiable concentrate.

The above is our summary of the cultivation techniques for Chonglou and its key management points. When planting Chonglou, growers should pay attention to choosing a good planting site as well as scientific planting and management. That is all for today's sharing.
