How to plant Bupleurum chinense DC.

1. Planting time: Bupleurum chinense can be planted in winter or spring, but it is recommended to sow in winter for yield. In this way, the survival rate of seedlings will be much higher in the coming year. Secondly, after winter dormancy, some unqualified seeds will be eliminated, and spring can be replanted according to the situation, which ensures the yield problem to some extent. Spring is also the most suitable season for the growth of Bupleurum chinense seeds, and sowing in winter can also give Bupleurum chinense more quality development time.

2, breeding: Bupleurum likes a humid and warm environment, and generally needs hydration before sowing. Like many other seeds, it is best to soak them in warm water first. Generally, the seeds need to be completely soaked in water for the first two hours, and some areas of the seeds need to be exposed to water after three hours, turning once an hour, about 3-4 times. The soaking time should not exceed 6 hours, and the temperature should be about 40℃. Finally, they should be buried in the soil to accelerate germination. Wait until the seedlings grow to about 8 cm before transplanting them into the soil.

3. Whole soil: weeds should be removed half a month before sowing, and then a certain amount of farmyard manure compost should be released, and the soil should be deeply turned. Secondly, the soil should not be too sticky or too wet, and it is best to present a certain slope. Arrange the land into strips, with the spacing of each hole about 12- 15 cm, and the depth is generally 2-4 cm. The soil layer is too thin for planting.

4. Fertilization: No topdressing is needed in the early stage of Bupleurum seedlings, only a small amount of fertilizer can be put when transplanting, the dosage is controlled at about 20 grams, and it can be evenly placed around the hole. Follow-up topdressing is more frequent, generally about 3 times, depending on the specific situation. It usually occurs one month before germination, flowering and harvesting. If the middle is suddenly too dry, you need to replenish water in time.

5. Management: Daily field management needs to pay attention to the following matters, and plants with diseases should be pulled out in time. To prevent plants from growing together alternately, they should be separated in time when they see each other. The accumulated water in the soil should be removed immediately to prevent rot and take root. Weeds and loose soil need to be removed before and after flowering.
