Bupleurum cultivation technique

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 propagation. 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 of 30 cm or a shallow hole at 23-27 cm. The treated seeds will be mixed well with grass ash at 0.5-0.75 kg per acre. Sprinkle in a 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 line 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 be 25 cm apart from each other by 10 cm. The plants are planted with the excavation and watered immediately after planting to ensure survive.
(3) Field management.
1 Miao Ding Miao. When the seedling height is 10 cm, the seedlings should be replenished in time.
2 cultivating weeding and fertilizing. Combined with cultivating and weeding for fertilization. When the seedling height is 10 cm, the light fertilizer water is applied once every 10-15 days, and it is applied continuously for 2-3 times. When the seedling height is 33 cm, the soil is applied and the human waste water is concentrated. 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 rows of 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 are root rot, spot blight, nodule nematode, rust, aphids, small tigers, cockroaches, and red stalks.
The prevention and treatment of nodule disease should pay attention to drainage and planting with gramineous crops. The drug control was controlled by carbendazim (50%) 600 times liquid.
Root nodule nematode disease occurs mostly on newly reclaimed land. When soil preparation, soil disinfection is carried out with 80% dibromochloropropane emulsifiable concentrate 100-150 times, and 1-1.5 kg per mu. Note that the seeding is 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 to 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.
