Planting Methods and Technical Key Points for Peucedanum praeruptorum
Peucedanum praeruptorum is a perennial herbaceous plant distributed in many parts 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 eliminating phlegm, and treating colds, coughs and bronchitis. Nowadays it is cultivated all over the country, with great planting potential. Let's take a look at its planting methods below.
1. Site selection and land preparation
Peucedanum praeruptorum is a perennial root plant that prefers a cool and humid climate. It is best suited to sandy loam with deep, loose and fertile soil. Planting in low-lying areas with poor drainage easily leads to root rot, while planting in heavy clay soil or dry, barren sandy soil results in poor growth. In the winter before planting, clear the weeds and leftover plant debris from the plot, burn or bury them deeply to overwinter, then after spring begins apply decomposed farmyard manure, rake the soil 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 planting. 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, spread the seeds evenly 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 management of Peucedanum praeruptorum planting is relatively simple and does not require much effort. The most important thing is weeding, and the methods of weeding include manual weeding and chemical weeding. Weeding must be done before sowing to avoid affecting seed emergence or causing slow emergence, which would affect later growth and development; at this time, chemical weeding 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 so that the solution is mixed in. For weeding after sowing, 150 ml of gramoxone aqueous solution can be mixed with 50 jin of water and sprayed; however, after emergence, chemical agents can no longer be used for weeding, lest the seedlings die, and manual weeding must be carried out at this time.
4. Fertilizer and water management
Peucedanum praeruptorum has little demand for fertility. After applying fertilizer per mu before planting, there is basically no need for further fertilization. After emergence, an appropriate amount of manure or urea can be applied to promote robust seedling growth. In the later stage, some compound fertilizer can be applied according to the growth state of the plants. When fertilizing, pay attention to the concentration to avoid damaging roots and leaves. In addition, Peucedanum praeruptorum is somewhat drought-tolerant. 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.
