Mainly used for the treatment of cold and fever, malaria, irregular menstruation and so on. There is a wide range of planting areas in China, but there are often some diseases and insect pests in the planting process, which seriously affect the yield of Bupleurum. So how to prevent and cure it? The following editor brings you the pest control skills of Bupleurum. Let's have a look!

1. Avoid continuous cropping

Rotation is one of the effective preventive measures to control diseases and insect pests of Bupleurum. Rotation can make full use of planting soil, ensure the healthy growth of Bupleurum and improve the ability of disease resistance. After crop rotation, due to the bacteria of Bupleurum diseases and insect pests can not find the host, resulting in its gradual death, the incidence rate gradually decreased. And due to the difference of medicinal materials, the soil microorganisms will gradually change to enhance the antibacterial activity of breeding. Therefore, reasonable crop rotation can prevent diseases transmitted by soil and plant residues, and reduce the incidence of soil-borne diseases.

2. Deep digging of ground preparation

Soil preparation is also a very important work when planting. Doing a good job of land preparation can destroy the overwintering sites of diseases and insect pests and eliminate the germs that remain in the soil and the insects that carry them. Reasonably adjust the soil structure, enhance soil fertility and reduce the incidence of diseases and insect pests. For example, if there are insects such as crickets or too much water in the soil, it can easily lead to root rot of Bupleurum. Therefore, we should take corresponding measures to improve the soil structure according to the specific diseases and insect pests, and then disinfect the soil before planting, or choose unplanted soil for planting.

3. Variety selection

Variety selection is also one of the main measures to prevent Bupleurum diseases and insect pests. We must choose varieties with strong disease resistance when planting and selecting seeds. The quality of varieties is directly related to the incidence of diseases and insect pests in the process of planting. If the disease resistance is not strong, then before planting, we should also do a good job of disinfection, eliminate hidden germs in seeds, and reduce the threat of diseases and insect pests. Therefore, when we select seeds, we should first give priority to disease resistance, and do not plant susceptible varieties in disease areas, and we must do a good job of seed soaking and disinfection before planting.

4. Planting management

The sowing time of Bupleurum is also very important, reasonable sowing time and sowing methods will have a certain impact on the occurrence of diseases and insect pests, so we should adjust the sowing time and sowing methods according to different planting areas and varieties. Then in the planting process to do a good job in weeding, pruning and other basic work, improve field permeability, reduce humidity, can effectively prevent diseases and insect pests. And properly increasing the proportion of phosphorus and potassium fertilizer can improve plant disease resistance and reduce the incidence of diseases and insect pests.

The above is a brief introduction of Bupleurum pest control skills. Bupleurum pest control is mainly based on prevention, we should try our best to avoid the occurrence of diseases and insect pests. Because no matter how timely you deal with it, it will have a certain impact on the growth of Bupleurum, and it is necessary to prevent some unwanted losses. That's all for today's introduction.
