How to Plant Paris polyphylla? Detailed Explanation of Cultivation Methods and Key Technical Points
When talking about Chonglou (Paris polyphylla), many people think of the Demon Lord Chonglou in Chinese Paladin, which is a classic in TV dramas. However, the Chonglou mentioned here is not that Chonglou. Today, what I want to talk about is the Chinese medicinal herb Chonglou (Paris polyphylla), which is mainly used to treat diseases such as boils and carbuncles, sore throat, snake and insect bites, traumatic injuries, and convulsions. So how is Paris polyphylla planted? Let's learn about it together.
1. Site Selection and Land Preparation
The planting site for Paris polyphylla is generally chosen in shaded areas with shade-providing objects, convenient drainage and irrigation, rich organic matter, and loose soil, such as woodlands and vegetable plots. Paris polyphylla is a shallow-rooted plant that grows relatively slowly, takes a long time for seedling cultivation, and has high soil requirements. Land preparation should involve clearing stones, weeds, and other debris from the field, breaking up soil clods, and leveling the ground. Of course, one important point is that fertilization should be combined with land preparation, with the base fertilizer mainly being decomposed organic fertilizer.
2. Sowing and Seedling Cultivation
Paris polyphylla is generally sown and cultivated into seedlings in January each year. Seeds should be plump, free from pests and diseases, and not moldy. Then the seeds are sun-dried for two to three days and mixed with river sand for germination, while keeping the river sand moist to ensure the seeds can breathe fully. Before sowing, carbendazim should be used to disinfect the soil, and then sowing can be carried out. When sowing, furrows are generally opened at a row spacing of 30 to 35 cm. Normally, seedlings emerge in about one week. During this period, soil moisture should be maintained to promote seedling emergence and seedling growth.
3. Scientific Transplanting
Generally, the seedling cultivation period is about one month, which means transplanting can be carried out after one month. In some cases, however, it is necessary to wait three years before digging out the seedlings for transplanting. When transplanting, the plants are generally set at a row spacing of 30 cm and a plant spacing of 20 cm. After transplanting, if the planting site cannot provide shade, then we also need to build a shade shed in advance. When transplanting seedlings, care should be taken to plant them with the soil attached, as this can improve the survival rate.
4. Field Management
We all know that Paris polyphylla is generally planted in March or April, and there is relatively a lot of rain at this time, so after transplanting there is no need to water, but at this time we should pay attention to proper drainage. Promptly dredge the field ditches and drain excess water from the field. If the weather is relatively dry, then reasonable irrigation is needed. Paris polyphylla is generally intertilled and weeded from September to October, and doing it twice is generally enough. When intertilling, be careful not to plow deeply, so as not to damage the root system of Paris polyphylla. 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 amounting to about 30 grams.
5. Pest and Disease Control
The main diseases of Paris polyphylla are root rot and leaf blight. Root rot mainly harms the root system of Paris polyphylla. The main cause of the disease is excessive moisture in the field, which leads to root rot and ultimately causes the plant to die. Leaf blight mainly harms the leaves of Paris polyphylla and is a fungal infectious disease. Carbendazim and Bordeaux mixture can be used to control them, respectively. The main pests are cutworms and white grubs, which can be directly killed with deltamethrin EC.
The above is the cultivation technology and management key points for Paris polyphylla compiled by the editor. When planting Paris polyphylla, growers should pay attention to choosing a good planting site as well as scientific planting and management. That's all for today's sharing.
