It is easy to plant rotten roots in low-lying areas with poor drainage, while planting on clayey soil and dry and barren sandy soil will lead to poor growth. In the winter before planting, clean up the weeds and residues of the land, burn them and bury them deeply through the winter, and then apply rotten farm manure after the beginning of spring, rake them fine and level them out for planting.

2. Sowing seeds

There are several propagation methods of Peucedanum praeruptorum, but its seed germination rate is high, so sowing and reproduction are more selected when planting. Its fruit ripens from September to October every year, when the pedicels are told together, put indoors for a period of time, rub the fruit, remove impurities, and put the seeds in a dry place to dry and store. The best sowing time is from November to January, because the seeds of Bupleurum sprouted slowly and should be sowed in advance. When sowing, sow the seeds evenly on the land, gently turn and flatten it, so that it is in close contact with the soil, generally using 3 kilograms per mu.

3. Field management

Bupleurum planting management is relatively simple, do not need to spend too much energy, the most important is weeding, weeding methods are artificial weeding and chemical weeding. Weeding should be done before sowing, so as not to affect the emergence of seeds or slow emergence, and affect the growth and development in the later stage. 10 days before sowing, 48% trifluralin EC 100ml can be sprayed on the ground, sprayed or turned shallowly to make the solution mix. Weeding after sowing can be sprayed with gram-free water agent 150ml with 50 jin of water, but after emergence, you can not use herbicides to avoid the death of seedlings, so artificial weeding should be carried out.

4. Fertilizer and water management

Peucedanum praeruptorum has little demand for fertility. after applying fertilizer per mu before planting, it is basically unnecessary to apply fertilizer, and some manure and urine fertilizer or urea can be properly applied after emergence, which can promote the growth of seedlings, and some compound fertilizers can be applied according to the growth state of the plant in the later stage. pay attention to the concentration when fertilizing, so as not to hurt the roots and leaves. In addition, Bupleurum can be slightly resistant to drought, it should be watered in time during drought, and it should be drained in time in rainy season to avoid rotting roots. Generally, it can grow normally without watering or drainage at ordinary times.
