Planting method of Bupleurum praeruptorum

Peucedanum is a perennial herb, distributed in many places in China, often wild in roadside or semi-shade hillside grass, its roots are commonly used in traditional Chinese medicine, antipyretic expectorant, cure cold cough, bronchitis role. Now it is cultivated all over the country, and its planting potential is great. Let's take a look at its planting methods.

1. Land selection and preparation

Peucedanum is a perennial plant. It likes cold and humid climate. It is suitable for deep soil layer and loose and fertile sandy soil. It is easy to rot roots in low-lying areas with poor drainage, while it will grow poorly in sticky soil and dry barren sandy soil. In winter before planting, weed residues on the plot are cleaned up, burned and buried deeply for winter, and then decomposed farm manure is applied after spring, and then it can be planted by raking and leveling.

2. Sowing

There are several methods of propagation of Peucedanum, but its seed germination rate is high, so it is more suitable for sowing and propagation when planting. Its fruit matures in September and October of each year. At this time, its pedicels are talked together. After being placed indoors for a period of time, the fruit is rubbed off, impurities are removed, and the seeds are placed in a dry place to dry and store for later use. Sowing time is best chosen in November-January, this is because the seeds of Peucedanum germinate slowly, generally to be sown in advance. When sowing, the seeds are evenly spread on the plot, gently turned and swept, so that they are in close contact with the soil, generally 3 kg per mu.

3. Field management

Peucedanum planting management is relatively simple, do not need to spend too much energy, the most important is weeding, weeding methods have artificial weeding and chemical weeding. Weeding should be done before sowing, so as not to affect the seed emergence or slow emergence, affecting the later growth and development, then weeding should be herbicide. 10 days before sowing, 48% trifluralin emulsifiable solution 100ml mixed with 100 jin of water can be sprayed on the ground, sprayed or shallowly turned to mix the solutions. Weeding after sowing can be sprayed with Gramoxone 150ml mixed with 50 jin of water; however, after seedling emergence, it is not allowed to use the pesticide to weed, so as to avoid the death of seedlings. At this time, manual weeding is required.

4. Fertilizer and water management

Peucedanum has little demand for fertility. After applying fertilizer per mu before planting, it basically does not need to apply fertilizer. After emergence, it can apply some manure or urea appropriately to promote the growth of seedlings. In the later stage, according to the growth state of plants, apply some compound fertilizer. Pay attention to the application concentration when fertilizing, so as not to damage roots and leaves. In addition, Peucedanum can be slightly resistant to drought. It should be watered in time during drought, and drained in time during rainy season to avoid rotten roots. Generally, it can grow normally without watering or draining at ordinary times.

The above is the planting method of Peucedanum, I hope to help you, if you want to know more about the cultivation of medicinal materials, please pay attention to us.
