Planting technology of celery in greenhouse

Soil preparation and fertilization: select flat land, renovate, fertilize and weed. Sowing: 7~8 days before sowing seed soaking germination, such as seed germination can be sown, more wet sowing method. Management: moderate watering, keep the field moist, timely control of pests and diseases.

Cultivation Technology of Celery in Greenhouse

1. Soil preparation and fertilization

Select land to be level and fine, renovate, fertilize, weed, etc. before planting. Because the temperature in the greenhouse has certain differences with the outside world, fertilization should be appropriate to avoid excessive fertilization caused by soil deterioration. Appropriately increase phosphorus and potassium fertilizer application, reduce nitrogen fertilizer use.

2. Building greenhouses

Under normal circumstances, choose a shed type span of 8~12m, a greenhouse length of 60~120m, three earth walls, three rows of columns, and it is best to use bamboo or steel stands on the columns. Use a drip-free film on the surface of the shed to increase the temperature inside the shed.

3. Sowing

Soak seeds 7~8 days before sowing. Soak the seeds in cold water at 12~14℃ for 12~24 hours, wash them, dry them in the cool air for a while, wrap them with wet towel, and put them in the cool place (15~20℃) to germinate in light. When seeds sprout, they can be sown. Wet sowing method is adopted, that is, watering bottom water first, sowing mixed with sand after water infiltration. After sowing, cover the soil thinly and evenly.

4. Management

To moderate watering, seedling bed to keep moist, seedlings 2 leaves a time seedlings, seedlings live, to carry out intertillage. When the seedlings grow to 5~7 pieces and the seedling height is 15~18cm, they can be transplanted. After planting, fertilizer and water management should be strengthened, diseases and insect pests should be prevented in time to ensure their normal growth and development.
