The Latest Planting Methods and Key Cultivation Techniques for Peucedanum praeruptorum
Peucedanum praeruptorum is a perennial herbaceous plant, distributed in many parts of China, often growing wild by roadsides or in semi-shaded hillside grass. Its root system is a commonly used traditional Chinese medicine, with effects of reducing fever and resolving phlegm, and treating colds, coughs and bronchitis. Nowadays it is cultivated in all regions, 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, and is best suited to sandy loam with deep, loose and fertile soil. Planting in low-lying areas with poor drainage tends to cause 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 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 used 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 place the seeds in a dry place to air-dry and store for later use. The best sowing time is from November to January, because the seeds of Peucedanum praeruptorum germinate slowly and generally need to be sown early. When sowing, scatter the seeds evenly over the plot, then gently turn and level the soil so that the seeds make close contact with the soil. Generally 3 kg of seed is used per mu.
3. Field management
The management of Peucedanum praeruptorum cultivation is relatively simple and does not require too much effort. The most important thing is weeding, and weeding methods include manual weeding and chemical weeding. Weeding must be done before sowing to avoid affecting seed emergence or slowing it down, which would affect later growth and development; at this time chemical weeding is suitable. Ten days before sowing, mix 100 ml of 48% trifluralin emulsifiable concentrate with 100 jin of water and spray it on the ground, then spray or shallowly turn the soil so that the solution is mixed in. For weeding after sowing, spray 150 ml of paraquat aqueous solution mixed with 50 jin of water; however, after emergence, chemical agents can no longer be used for weeding, to avoid killing the seedlings, so 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, basically no further fertilizing is needed. After emergence, an appropriate amount of manure or urea can be applied to promote strong seedling growth, and later, depending on the growth state of the plants, some compound fertilizer can be applied. When fertilizing, pay attention to the concentration applied to avoid damaging roots and leaves. In addition, Peucedanum praeruptorum can tolerate drought somewhat; water promptly during drought, and drain promptly during rainy seasons to avoid root rot. Generally, no watering or drainage is needed in normal times for it to grow normally.
