Bupleurum genus Umbelliferae is a perennial herb that enjoys a warm and humid climate, is cold-tolerant, drought-tolerant, and suitable for planting in deep, fertile sandy loam. Seed production or seedling transplanting can be used in production.

(1) Seed reproduction. Two years after the planting of Bupleurum, the mature seeds were collected, dried, threshed and stored in September. Seed treatment was carried out half a month before sowing, and Bupleurum seeds were soaked in 50 μg/g 6-BA for 24 hours, then 1 part of seeds and 3 parts of wet sand were placed in the container, and the seeds were taken out for 12 days. Spring sowing or autumn sowing can be carried out in spring. In spring, in late March, the strips will be opened at a shallow ditch or a hole at a distance of 30 cm to open a shallow hole at 23-27 cm. The treated seeds will be mixed well with the grass ash at 0.5-0.75 kg per acre. Sprinkle in the shallow hole in the ditch, cover the soil, cover the straw and then water. The autumn sowing was planted before freezing, and the row spacing was the same as that of spring sowing.

(2) Seedling transplanting. In late March, the treated seeds are spread or broadcast. Spread the seeds, make a mess on the finished surface, spread the seeds evenly on the noodles and cover the soil. The seeding was carried out by ditching at a row spacing of 10 cm. After sowing, the soil was covered with grass and watered. Appeared in about 10 days. When the root diameter is 2-3 mm and the root length is 5-6 cm, the transplanting is carried out, and the cloudy day is selected. The thick and disease-free seedlings are selected to have a row spacing of 25 cm and a plant spacing of 10 cm. The plants are planted with the excavation and watered immediately after planting to ensure survive.

(3) Field management.

1 Miao Dingmiao. When the seedling height is 10cm, the seedlings will be replenished in time.

2 cultivating weeding and fertilizing. Combined with cultivating and weeding for fertilization. When the height of the seedling is 10cm, apply the light fertilizer water once every 10-15 days, and apply it continuously for 2-3 times. When the seedling height is 33cm, the soil will be fertilized and the human waste water will be applied. In the second year, cultivating weeding and fertilizing 2-3 times.

3 picking buds. The flower buds and flower buds were removed in time from August to October.

4 row irrigation. Before the emergence of the seedlings, the soil should be kept moist. After the emergence of the seedlings, the small water should be poured frequently. When the drought occurs, the water should be watered in time, and the rainy season should pay attention to the drainage.

(4) Pest control. The main pests and diseases of Bupleurum have root rot, spot blotch, nodule nematode, rust, aphids, small tigers, cockroaches, and red stalks.

The prevention and treatment of nodule disease should pay attention to the drainage and planting of gramineous crops. The drug control was controlled by carbendazim (50%) 600 times liquid.

Root nodule nematode disease occurs mostly on newly reclaimed land. When the soil is prepared, the soil is disinfected with 100% dibromochloropropane emulsifiable concentrate 100-150 times, and 1-1.5 kg per mu. Note that the seeding will be carried out half a month after the treatment.

Spot blotch, damage to the leaves, avoid continuous cropping, use 1:1:120 Bordeaux liquid spray control.

Other pests and diseases can be controlled with the corresponding pesticides.

(5) Harvesting. Bupleurum was harvested 2-3 years after sowing. Cut the excavated roots to the stems, dry them, and bundle them into small bundles. The average yield is 150kg per dry.
