Detailed Explanation of Saposhnikovia divaricata Planting Methods and Technical Key Points
Saposhnikovia divaricata, also known by the aliases Tongyun, Huiyun, and Huicao, is a commonly used Chinese medicinal herb mainly used to treat colds, headaches, joint pain, and other conditions, and it has extremely high economic value. Many people have obtained considerable returns by growing it. So how do you plant Saposhnikovia divaricata? Do you know? Let's take a look below with the editor.
1. Land Selection and Preparation
Saposhnikovia divaricata has strong cold resistance and drought resistance, and it dislikes waterlogging or overly wet soil, so when planting, try to choose plots with higher terrain and facing the sun, rather than low-lying and damp places. It is not strict about soil requirements, but to achieve high yields, it is best to plant it in sandy loam with deep soil layers, loose and fertile soil, and good drainage. Soil with heavy clay content or strong acidity or alkalinity is not suitable for planting. Saposhnikovia divaricata is a perennial plant, so to allow it to grow smoothly, sufficient base fertilizer should be applied before planting. Apply 3000-4000 kg of farmyard manure and 20 kg of calcium phosphate per mu, plow them deeply into the soil, and then make raised beds.
2. Propagation Methods
Saposhnikovia divaricata has two propagation methods: seeds and root division, among which seed propagation is mainly used, so we will explain seed propagation in detail. The sowing time can be chosen in spring or autumn. Spring sowing is generally in March-April, while autumn sowing is in September-October. Before sowing, the seeds must first be treated by soaking them in warm water for 24 hours so they fully absorb water before sowing. When sowing, generally open furrows on the bed surface for drilling, with a furrow depth of 2-3 cm, sow the seeds into them, then cover with soil and press firmly, and water to keep the soil moist. Seedlings can emerge within one month. Generally, 2-2.2 kg of seeds are used per mu.
3. Field Management
When the seedlings grow to 4-5 cm, thin them promptly, controlling the plant spacing at 5-7 cm; when the seedlings grow to more than 10 cm, finalize the seedlings promptly, controlling the plant spacing at about 15 cm. After finalizing the seedlings, carry out 2-3 times of intertillage and weeding each year to keep the field clean and prevent weeds from affecting plant growth. During intertillage, earthing up can also be done at the same time. Earthing up in summer prevents lodging, and earthing up in winter helps the root system overwinter. June-August is the peak growth season for the plants, so topdressing should be done 2 times. Each topdressing can use human and animal manure and urine and superphosphate, applied in furrows between the rows. In addition, Saposhnikovia divaricata should be timely de-budded. Except for those kept for seed in the second year, all should be de-budded. Saposhnikovia divaricata has strong drought resistance, so no irrigation is needed; during rainy periods, drain water promptly to prevent waterlogging, so as to avoid root damage.
4. Pest and Disease Control
When planting Saposhnikovia divaricata, it will suffer from several common pests and diseases, namely powdery mildew, Loxostege palealis, and Papilio macilentus. Powdery mildew mainly develops during high-temperature periods in summer and autumn, and mainly harms the leaves. When planting, applying more phosphorus and potassium fertilizer can improve disease resistance, and strengthening ventilation and light transmission between plants can prevent this disease. When the disease occurs, spray thiophanate to control it. Loxostege palealis and Papilio macilentus mainly harm the leaves, buds, and fruits of the planted plants, and can be controlled by spraying trichlorfon or dichlorvos.
