What are the main cultivation techniques of carnation?

① prepares the land to build beds. In order to avoid continuous cropping land in field cultivation, fields with high topography, thick soil layer, loose texture, rich humus and good drainage should be selected, which should be deeply turned and exposed to the hot sun in order to achieve the purpose of soil disinfection. The mature organic fertilizer and a small amount of compound fertilizer were applied 3 weeks before planting, and the border surface was formed according to the row spacing of 20 cm × 40 cm and two rows of each species.

② colonization. The border was watered once before planting, and when the water seeped and the soil was not sticky, it was planted according to the plant spacing of 20 cm × 40 cm, so that the seedlings were watered once along with the planting.

③ core plucking, sprouting and setting up net frame. When the plant grows 5-6 pairs of leaves, it is necessary to pick the heart and promote the lateral buds. The number of lateral buds is determined according to the planned cut flower yield. Generally, there are 5-6 lateral buds per plant, and the rest are erased. After picking the heart, it is necessary to set up a grid in time so that the branches can be fixed on the Internet.

④ rain shelter cultivation facilities. Due to the strict water requirements of carnation, it is necessary to use rain-shielding cultivation facilities or greenhouse cultivation to prevent it from being directly drenched by rain, let alone by heavy rain. The facilities should be ventilated and well lit.

⑤ fertilizer and water management.

a. Fertilizer: the times of topdressing and the amount of fertilizer used are determined according to the growth trend, and the thin compound liquid fertilizer of nitrogen, phosphorus and potassium is generally applied every 15 days or so.

b. water. In the seedling stage, the soil moisture should be high, and more watering should be needed at this stage; in the middle growth stage, the soil moisture should be reduced and watering should be properly controlled; after budding, the soil moisture should be kept in the semi-moisture state; otherwise, the flower stem would be weak or not.

⑥ harvested in good time. When half of the main flower branches are open, the main flower branches are cut first, and the lower side flower branches can be harvested in stages and batches. The florescence can also be adjusted by sowing and planting by stages or by coring treatment.
