Gentiana likes wet and cool environment, so it is necessary to choose an environment with sufficient water for its growth. In addition, the terrain of the planting land should be relatively flat, and it is best to have sufficient light. At the same time, attention should be paid to the fertility of the soil. Some soil rich in organic matter should be selected, and sticky soil should be avoided when selecting soil. In addition, deep ploughing of the soil should be carried out before planting, and base fertilizer should be applied in combination with ploughing.

2, loose soil weeding

When gentian grows, the existence of weeds will affect the growth of gentian to a certain extent, so regular weeding should be carried out to avoid weeds. When weeding, a proper body, soil in the lack of organic matter and water will appear hardening phenomenon, this situation will cause root breathing difficulties, adverse to its growth, serious will lead to root suffocation death. Therefore, it is necessary to loosen the soil properly, but pay attention not to damage the roots of Gentiana when loosening the soil. It should not be too deep when loosening the soil.

When planting gentian, it must be properly supplemented with water to avoid the impact of dryness on its growth. When the soil is severely dry, gentian will wither due to lack of water, and when it is serious, it will lead to plant death. It is also necessary to carry out topdressing. Fertilization is essential for crop growth. Foliar fertilizer should be sprayed twice when topdressing, and phosphate fertilizer and farm manure should be applied in combination. When gentian buds, except for the seed plants, the rest of the buds should be removed, which not only can improve the yield and quality, thus reducing the consumption of nutrients, but also can concentrate nutrients to supply rhizome growth.

4. Pest control

It is necessary to prevent and control diseases and insect pests. Gentiana is easy to suffer from spot blight under normal circumstances. This disease mainly harms Gentiana leaves and brings some damage to them, even death. Therefore, in order to prevent this disease, the soil should be disinfected before planting, the seedlings should also be disinfected, the planting density should be controlled, the diseased planting can be destroyed, the bacteria can be eliminated, and the diseased holes should be disinfected to prevent the bacteria from infecting other planting through the soil.
