Planting Techniques and Cultivation Management Methods for Thesium chinense
Thesium chinense, also known as Bainucao, Xixucao and Qinglongcao, has whole plants that can be used as medicine. It has the effects of clearing heat and detoxifying, tonifying the kidney and astringing essence, and can treat heatstroke, acute mastitis, pneumonia, tonsillitis and other conditions. Thesium chinense is widely distributed across north and south China, and often grows in sandy grasslands or beside stone ridges. So how should it be planted? Let's take a look together.
1. Site Selection and Land Preparation
Thesium chinense prefers light and a warm, moist environment, and can also tolerate a certain degree of drought. When planting, it is enough to choose ordinary plots with high, dry terrain and good drainage. To obtain high yields, it is advisable to choose fertile, loose soil; soil that is too barren will affect the number and quality of its flowers. Because Thesium chinense is a perennial herbaceous plant, base fertilizer must be applied before planting. The base fertilizer should be mainly organic fertilizer, applying 2500 kg of decomposed farmyard manure and 50 kg of superphosphate per mu. After shaping and raking level, form ridges or beds for later use.
2. Sowing and Seedling Raising
Direct sowing or seedling transplanting can be used. When the fruit matures from July to August each year, collect the seeds. For direct sowing, carry out spring sowing in mid-to-late April, or autumn sowing from October to November. On the prepared ground, open furrows at a row spacing of 20 cm and sow in drills, covering with 1-2 cm of soil. Use 0.75-1 kg of seed per mu. After sowing, press lightly and water. Generally, seedlings emerge after half a month. For seedling transplanting, generally sow in drills on a seedbed in March of spring, cover with 1 cm of soil after sowing, keep the seedbed moist at all times, and control the temperature at 15-20 degrees. Seedlings emerge after about 10 days. Strengthen management between seedlings, and when the seedlings grow to 6-10 cm, they can be transplanted. Try to transplant in the afternoon after rainy days, when the survival rate is high. At the time of transplanting, control the plant and row spacing at 20×25 cm.
3. Field Management
Thesium chinense plants are short and small, so during the growth period, weeds must be removed frequently to prevent weeds from affecting plant growth and competing with the plants for water and fertilizer. In addition, if weeds grow taller than the plants, they can easily breed pests and diseases and affect the normal photosynthesis of the plants. For annual seedlings after loosening soil and weeding, or for seedlings that have grown for 2-3 years, after fertilizing and watering, cover with wheat straw, wheat bran, sawdust or the like. This can strengthen the decomposition of microorganisms in the soil, maintain moisture, reduce weeds, and create a good growth environment for Thesium chinense.
4. Fertilizer and Water Management
Thesium chinense likes a dry environment. Apart from appropriate watering during the early seed germination stage and seedling growth stage, it does not need frequent watering in the later growth stage, so as not to affect its growth. After the rainy season, drain water in time to avoid root rot. Apply fertilizer once each in spring and winter every year. This can promote root growth and increase yield. Fertilization should be mainly phosphate fertilizer, applying 20-25 kg per mu. During the peak growth season, a potassium fertilizer solution can be sprayed to improve the plant's disease resistance, which has an obvious effect on increasing yield.
