The latest planting methods and precautions for Bupleurum
Bupleurum is a commonly used antipyretic drug for reducing fever, relieving pain, and promoting bile secretion. It can also be used to treat diseases such as colds with fever and respiratory infections. It is mainly divided into Northern Bupleurum, Yinzhou Bupleurum, Black Bupleurum, Red-purple Bupleurum and Cone-leaf Bupleurum. In China, it is mainly produced in the northwest and southwest plateau regions. So how is Bupleurum cultivated? And what should be noted during the cultivation process? Let's take a look together at what today's editor wants to share.
1. Land cultivation
Based on the growth habits of Bupleurum, we can choose a suitable planting site for it. Generally, we choose sandy soil that is fertile, loose in texture, good in permeability, well-drained, and convenient for irrigation. Saline-alkali land and heavy clay land cannot be used to plant Bupleurum. Deeply plow the soil, and spread sufficient farmyard manure, combined with phosphate fertilizer as base fertilizer. Open furrows and make beds, level the ground, and then planting can begin.
2. Scientific planting
Bupleurum can generally be planted in spring or winter, but the best time for planting is winter. The survival rate and later yield of planting this way will be about 20 percent higher. Before sowing, we need to put the seeds into warm water at about 50 degrees to scald them, remove the seeds after about ten minutes, and soak them in a carbendazim solution for about half an hour. After removing them, rinse them clean with water, dry off the moisture, and then sow.
3. Field operations
The emergence of Bupleurum seedlings is related to some extent to soil temperature and soil moisture. In a suitable environment, seedlings generally emerge in about half a month, but if the humidity is not up to standard, it generally takes two to three months for seedlings to emerge. After the Bupleurum seedlings emerge, we should strengthen field management operations, water in a timely manner, fertilize scientifically, and at the same time carry out reasonable intertillage and weeding. When the seedlings grow to about 15 cm, we should maintain the field density at this time, generally keeping the spacing between plants at about 25 cm.
4. Pest and disease control
The main disease of Bupleurum is root rot, which mainly occurs in hot and rainy seasons. First, we need to strengthen field management and do a good job of drainage in a timely manner. Then we can also enhance the plant's resistance by applying more phosphate fertilizer and potassium fertilizer. The most common pest of Bupleurum is aphids, and we can directly use dimethoate or trichlorfon for control.
5. Precautions
Bupleurum is a commonly used Chinese medicinal material, so there are many things to pay attention to when planting it. For example, in terms of pest and disease control, we generally still need to strengthen field management to achieve the effect of preventing pests and diseases. It is best not to spray pesticides, as this will have a certain impact on the medicinal quality. Second, we should do a good job of moisture retention. After sowing, cover with a layer of rice straw, which can effectively retain moisture. Finally, use chemical fertilizers as little as possible or not at all, and mainly rely on farmyard manure.
