1、 Soil

According to the characteristics of drought resistance and waterlogging resistance of bupleurum, loam, sandy loam or gentle slope with deep soil layer, loose air permeability and good drainage should be selected in soil selection. Before planting, plough and rake for many times, and apply 30000 kg / ha of rotten stable manure as base fertilizer

2、 Moisture

Bupleurum likes to grow in humid soil environment, but it is most afraid of ponding and immersion in the ground. Before the rainy season comes, the border ditch shall be cleaned in time to ensure smooth drainage and reduce the occurrence of field diseases, so as to make the plants grow healthily

3、 Fertilization

The first fertilization of Bupleurum was carried out in combination with intertillage at the first thinning, the second fertilization was carried out in combination with intertillage at the time of seedling fixing, and the third fertilization was carried out at the time of seedling height of 30-40 cm. For separate supplementary application of potassium fertilizer, organic potassium fertilizer can be sprayed on the leaves, and 30000 kg / ha of rotten manure can be applied as base fertilizer

4、 Illumination

When it is in the seedling state, it cannot be irradiated by direct light, and it should be shaded. After growing and maturing, there should be enough sunshine, and the sunny environment will be more conducive to its growth. In general, it can grow well as long as it is maintained in the environment without shading
