The Latest Cultivation Techniques and Methods Tutorial for Stephania tetrandra
Stephania tetrandra, also known as fenfangji or mufangji, is a traditional Chinese medicinal herb in China. It has the effects of promoting diuresis and reducing swelling, and dispelling wind and relieving pain. It has good therapeutic effects on many diseases, and can also protect the liver and detoxify, with extremely high medicinal value. Due to huge market demand and the depletion of wild resources, many regions have begun to cultivate it domestically. So how should Stephania tetrandra be cultivated? Let's take a look together.
1. Site Selection and Land Preparation
It prefers a warm and humid environment and avoids drought and waterlogging, so when planting, it is best to choose well-drained, deep, fertile and loose sandy loam soil, preferably on hillsides or wasteland. Before planting, plow deeply and sun the soil, using sunlight to kill soil-borne pests and disease sources. Then apply base fertilizer, shape and rake level, and make raised beds. The beds should be 25-30 cm high and 1.2-1.3 m wide, with drainage ditches made properly. If conditions permit, formaldehyde solution can be sprayed for disinfection and sterilization.
2. Propagation Methods
⟦NL>Stephania tetrandra can be propagated by two methods: seeds and cuttings. Seed propagation can be carried out by sowing in early spring or late autumn, using the drill sowing method. Open furrows on the bed surface at a row spacing of 20 cm, evenly scatter the seeds into the furrows, and cover with a thin layer of soil. After sowing, straw can be spread over the bed surface to keep warm and moist, which helps with seedling emergence. For cutting propagation, first select vigorous, pest-free 1-2 year old thick vines from healthy mother plants as cuttings, cut them into 10-15 cm lengths, and insert them in March-April, that is, around Qingming. Insert them at a plant and row spacing of 10×15 cm, with one third of the cutting inserted into the soil. After insertion, water them and cover with grass to keep warm and moist.3. Field Management
Stephania tetrandra seedlings prefer shade, so after the seedlings emerge and after cuttings are inserted, appropriate shading should be provided. They can also be intercropped with other tall-stalk crops to promote rapid seedling growth. In spring, timely cultivating and weeding should be carried out to prevent weeds from spreading and affecting seedling growth. After rain, the soil tends to become compacted, so frequent cultivating and loosening of the soil should be done to facilitate plant growth. After transplanting, water frequently to keep the soil moist, which helps the plants survive. After the plants survive, water less, especially during the rainy season, and drain promptly to avoid root rot. During the flowering period, the plants consume a large amount of nutrients, so at this time, 2500 kg of human and animal manure fertilizer should be applied per mu as a top dressing. After the beginning of spring, another 150 kg of farmyard manure should be applied per mu as a top dressing to promote bud differentiation.
4. Pest and Disease Control
Diseases of Stephania tetrandra generally occur during the high-temperature and high-humidity period in summer. At this time, the main diseases include leaf spot and root rot. When leaf spot occurs, Bordeaux mixture can be sprayed for control; root rot can be controlled by spraying copper sulfate. Pests include swallowtail butterflies, aphids, and scarab beetles. Swallowtail butterflies can be controlled by spraying trichlorfon; aphids can be controlled by spraying dimethoate; scarab beetles can be controlled by spraying trichlorfon.
