The latest tutorial on cultivation techniques and methods for white wormwood
White wormwood is the whole plant of Artemisia sieversiana, an Asteraceae plant, also known as reed wormwood, pine-needle mugwort, and yinchen grass. It is both a wild vegetable and a traditional Chinese medicine. The whole plant can be used as medicine and can treat wind-cold-dampness arthralgia, jaundice, heat dysentery, and scabies and malignant sores. So how should white wormwood be cultivated? Let's learn about it together.
1. Site selection and land preparation
White wormwood generally grows wild by riversides, in grasslands, and on wasteland. It is not strict about soil and can grow in many types of soil, but when planting, it is best to choose sandy loam with sufficient fertility, loose soil texture, and good drainage. The planting site is best facing the sun with sufficient light. Before planting, plow the soil deeply 25-30 cm, apply 1500-2000 kg of decomposed farmyard manure per mu as base fertilizer, rake it fine and level it, then make beds or ridges, and at the same time dig drainage ditches well for drainage and irrigation.
2. Sowing
The propagation methods of white wormwood are seed propagation and division propagation. In production, seed propagation is generally used. The sowing time is generally in February to March. Dig furrows or holes on the bed surface, mix the seeds evenly with fine sand at 1:2, evenly scatter them into the furrows or holes, cover with soil, and water. After emergence, manage the seedling stage well, timely carry out intertillage and weeding as well as thinning and filling in gaps. When the seedlings grow to 10-15 cm, they can be transplanted. Transplanting should control the plant and row spacing at about 20-25 cm.
3. Field management
One week after planting, white wormwood has basically survived. At this time, check promptly. If there is no continued growth or dead plants are found, replant them promptly. After replanting, fertilize in combination with intertillage and weeding to promote faster and better growth of the seedlings. Fertilization should be carried out in combination with intertillage and watering, which can not only avoid concentrated fertilizer damaging seedling growth, but also improve fertilizer use efficiency. Intertillage can loosen the soil and avoid soil compaction, so as to prevent root respiration from being blocked, promote root growth, allow the plant to absorb more nutrients, and promote stem and leaf growth.
4. Pest and disease control
The main diseases of white wormwood are root rot and sclerotinia disease. Root rot, as the name implies, is a disease that harms the root system. Once it is not controlled in time, it will cause the roots to rot, gradually causing the plant to wither and die. For it, water management should be done well, and drainage should be timely in the rainy season. When the disease occurs, chlorothalonil can be used for root irrigation. Sclerotinia disease is a fungal disease with strong infectivity. For it, Bordeaux mixture can be sprayed in the early stage of the disease for control. The effect is relatively good. Pests mainly include cutworms, aphids, and others, which harm the leaves, roots, and young tender parts of the plant. In severe cases, they can eat the plant clean in a short time. Trichlorfon, dimethoate emulsion, dichlorvos, and other pesticides can be used for spraying and killing.
