What are the key technical points for growing Saururus chinensis?
Saururus chinensis, also known as tangbianou, has medicinal uses for the whole plant. Taken internally, it treats urinary tract infections, urinary tract stones, and edema from athlete's foot; applied externally, it can treat carbuncles, boils, and skin eczema. Its medicinal effects are powerful. Because of its strong medicinal efficacy, it is cultivated in many regions. Let's take a look at its growing methods below.
1. Site selection and land preparation
Saururus chinensis prefers a warm and humid climate and has strong shade tolerance. It is not demanding about soil and can be grown in shallow water areas such as beside ponds, ditches, and streams, or in low-lying land. Before planting, clear the weeds from the plot thoroughly. If conditions allow, the soil can also be disinfected and sterilized. If soil fertility is good, no base fertilizer may be applied. If the soil is relatively poor, some base fertilizer can be applied appropriately to ensure the nutrients needed for plant growth. Base fertilizer should mainly be organic fertilizer, which can provide a variety of nutrients for the plants.
2. Propagation methods
Saururus chinensis can be propagated by seeds and by division. For seed propagation, in autumn when the fruits are ripe and split open, pick fully mature fruits, rub off the fruit skin, remove the plant parts, and remove impurities. When sowing, open shallow furrows in the plot for drilling, then evenly scatter the seeds into the furrows and cover with 1-1.5 cm of soil. For division propagation, in April, dig up the underground rhizomes of the mother plant, cut them into small sections, each section requiring 2-3 buds, and use the hole planting method. Dig holes in the plot at a spacing of 30×30 cm, and plant one plant per hole.
3. Field management
After sowing, water frequently to keep the soil moist, which helps emergence, but do not water too much and cause waterlogging, lest the seeds fail to germinate or rot. After emergence, carry out field management well and remove weeds promptly so they do not seize nutrients and growing space and affect seedling growth. When seedlings grow to 3-5 cm, thin them promptly to increase air permeability and promote seedling growth. In addition, topdressing can be combined with cultivating and weeding, applying 8-10 kg of urea per mu, but attention should be paid to the fertilizer concentration. It can be dissolved in water and applied by watering, which can both speed up seedling absorption and improve fertilizer use efficiency.
