How to grow Teasel (Dipsacus asper)? Latest planting techniques and method tutorial
Teasel, also known as "monk's head," is a traditional Chinese medicinal herb named for its ability to knit broken bones. It tonifies the liver, strengthens bones and muscles, and regulates the meridians; it can treat abnormal vaginal discharge, relieve aching bones and muscles, and treat coughing with blood. So how do you grow teasel? Follow along with us for a detailed introduction.
1. Site selection and land preparation
Teasel is suitable for cultivation in areas above 1600 m in elevation. It is not demanding about soil, but sandy loam with deep soil layers, good drainage, and loose texture is ideal. If planted in compacted or nutrient-poor soil, its root system will grow poorly and branch excessively, which affects quality, and in summer's high temperature and high humidity it is prone to root rot. Before planting, apply 2000 kg of decomposed farmyard manure and 50 kg of compound fertilizer per mu as a base fertilizer while preparing the land. After shaping and leveling, make high beds with furrow width of 30-40 cm to facilitate watering and drainage.
2. Sowing and raising seedlings
Seed propagation is generally used, and sowing is generally done in two ways: direct seeding and seedling transplanting. In high-cold regions, the seedling transplanting method is generally used, which can fully improve the utilization rate of the land. Sowing time is generally in summer from June to July. Before sowing, soak the seeds in warm water for 10 hours so they absorb enough water, then place them in a warm place to germinate. During germination, water 1-2 times a day, and sow once the sprouts begin to stir. When sowing, water the bed surface thoroughly, then mix the seeds with fine soil at a ratio of 1:3 and broadcast evenly over the bed surface, generally using 10 kg of seed per mu. After sowing, cover with a thin layer of soil, or cover with grass to keep warm and moist; remove it promptly once the seedlings emerge, and strengthen weeding at the same time.
3. Transplanting and planting out
After the following spring, once the soil has thawed, transplanting can begin. When lifting the seedlings, first water thoroughly, then gently pull up the seedlings; if the soil is compacted, loosen it with a small hoe or trowel before lifting the seedlings. After lifting, place the seedlings in a cool, ventilated place; ideally transplant them immediately after lifting, and no later than 48 hours, to avoid affecting the survival rate. When planting, keep a plant spacing of 20-25 cm and a row spacing of 30-40 cm, generally planting about 1500 plants per mu. When planting out, be sure to spread the seedling roots out, and after transplanting water thoroughly to settle the roots.
4. Field management
After transplanting, cultivate and weed promptly to promote seedling growth, but be careful when cultivating not to damage the roots and leaves. Later, carry out 2-3 more rounds of cultivation and weeding to ensure there are no weeds in the field. Twenty days after transplanting, when the seedlings turn green again, apply once per mu a thin slurry of human and livestock manure water of 1500-2000 kg plus 20 kg of urea, which can promote rapid seedling growth. In addition, later on, do a good job of pest and disease control so that pests and diseases do not affect quality and yield.
