What is Peucedanum praeruptorum? Understanding the benefits and cultivation methods of this perennial herb
Peucedanum praeruptorum is a perennial herb distributed across many regions of China, often growing wild along roadsides or in semi-shaded hillside grass. Its root system is a commonly used traditional Chinese medicine, with effects of reducing fever and dispelling phlegm, and is used to treat colds, coughs and bronchitis. Nowadays it is cultivated throughout the country and has great planting potential. Let's take a look at its cultivation methods below.
1. Site selection and land preparation
Peucedanum praeruptorum is a perennial-root plant that prefers a cool and humid climate. Deep, loose and fertile sandy loam is most suitable. Planting in low-lying areas with poor drainage easily causes root rot, while planting in heavy clay soil or dry, barren sandy soil leads to poor growth. In the winter before planting, clear the weeds and leftover plant debris from the plot, burn or deeply bury them to overwinter, then apply decomposed farmyard manure after the beginning of spring, rake it fine and level it, and planting can begin.
2. Sowing
There are several propagation methods for Peucedanum praeruptorum, but since its seeds have a high germination rate, sowing propagation is mostly chosen for cultivation. Its fruits mature from September to October each year. At this time, cut them down together with the flower stalks, place them indoors for a period, then rub off the fruits, remove impurities, and dry the seeds in a dry place for storage. The best sowing time is from November to January, because the seeds of Peucedanum praeruptorum germinate slowly and generally need to be sown in advance. When sowing, evenly broadcast the seeds over the plot, then gently turn and level the soil so that the seeds are in close contact with the soil. Generally, 3 kg of seed is used per mu.
3. Field management
The cultivation and management of Peucedanum praeruptorum is relatively simple and does not require much effort. The most important thing is weed control, which can be done manually or with herbicides. Weeds must be controlled before sowing to avoid affecting seed germination or causing slow emergence, which would affect later growth and development; at this time, chemical weed control is preferable. Ten days before sowing, 100 ml of 48% trifluralin emulsifiable concentrate can be mixed with 100 jin of water and sprayed on the ground, then sprayed or shallowly turned in so the solution is mixed into the soil. For weed control after sowing, 150 ml of gramoxone aqueous solution can be mixed with 50 jin of water and sprayed; however, after emergence, chemical herbicides can no longer be used, as they may cause the seedlings to die, so manual weeding must be carried out at this stage.
4. Fertilizer and water management
Peucedanum praeruptorum has little demand for nutrients. After applying fertilizer per mu before planting, basically no further fertilization is needed. After emergence, a suitable amount of manure or urea can be applied to promote strong seedling growth. In the later stage, some compound fertilizer can be applied according to the growth status of the plants. When fertilizing, pay attention to the concentration to avoid damaging roots and leaves. In addition, Peucedanum praeruptorum can tolerate drought slightly. Water timely during drought, and drain promptly during the rainy season to avoid root rot. Generally, no watering or drainage is needed in normal times for it to grow normally.
