Key Points of Baihao Planting Technology and Field Management Methods
Baihao is the whole plant of Artemisia sieversiana, a plant in the Asteraceae family. It is also known as Luhao, Songmaoai, and Yinchencao. 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 Baihao be planted? Let's learn about it together.
1. Site selection and land preparation
Baihao generally grows wild by riversides, on grasslands, and in wasteland. It has low requirements for soil and can grow in many types of soil, but when planting, it is best to choose sandy loam with sufficient fertility, loose soil, 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 Baihao are seed propagation and division propagation. In production, seed propagation is generally used. The sowing time is generally from 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, do a good job of seedling-stage management, timely carry out intertillage and weeding as well as thinning and replanting. When the seedlings grow to 10-15 cm, they can be transplanted. For transplanting, control the plant and row spacing at about 20-25 cm.
3. Field management
One week after planting, Baihao has basically survived. At this time, check in time. If there is no continued growth or dead plants are found, replant them in time. After replanting, apply fertilizer 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. This can not only avoid concentrated fertilizer damaging the growth of the seedlings, but also improve the utilization rate of the fertilizer. Intertillage can loosen the soil and avoid soil compaction, so as not to hinder root respiration, 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 Baihao are root rot and sclerotinia. Root rot, as the name suggests, is a disease that harms the root system. Once it is not controlled in time, it will cause the roots to rot, causing the plant to gradually wither and die. For it, water management should be done well, and drainage should be carried out in time during the rainy season. When the disease occurs, chlorothalonil can be used for root irrigation. Sclerotinia 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. The main pests 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. They can be killed by spraying trichlorfon, dimethoate emulsion, dichlorvos, and other pesticides.
