A Detailed Guide to Celery Seedling Raising Time and Methods in Autumn
Celery is surely familiar to everyone; it is a vegetable that everyone very much likes to eat, and it is widely cultivated in our country, and July to August every year is a good season for raising celery seedlings. Below, let us learn with the editor how celery seedlings are raised. When is the best time to raise seedlings? Let us take a look.
Celery seedling raising time
For spring cultivation, seedlings are generally raised indoors in a greenhouse during January to February, transplanted in March to April, and can be harvested in May to July. For summer cultivation, sowing is generally carried out in March to May, and the seeds need to be soaked for 24 hours before sowing; after the seedlings emerge, thin them in time, keeping the spacing between seedlings at about 2 cm. When sowing in April, there is no need to cover with film; before sowing and emergence, cover with a shade net to help retain moisture. For autumn cultivation, sowing and seedling raising are generally carried out from early June to mid-July, and transplanting is done from late July to late August. Because the autumn sowing period falls in a high-temperature season, and the suitable germination temperature for celery seeds is between 15-25 degrees, emergence is difficult above 30 degrees, so low-temperature germination promotion treatment is needed for planting.
Seedling raising methods
1. Seedbed selection
For the seedbed, it is recommended to choose plots with a relatively high sand content, sufficient moisture, and good permeability as the seedling site. To make the seedbed sufficiently fertile, an appropriate amount of farmyard manure can be spread, and the soil should be plowed evenly.
2. Seedling raising
Based on the local climate, market demand, and so on, choose varieties suitable for planting. Treat the seeds to promote germination; before promoting germination, first soak them in clean water, and stir thoroughly during soaking, as this helps the plants absorb water fully. After soaking for one day, the seeds can be placed in a temperature environment to promote germination.
3. Key points of germination promotion
During the germination promotion process, the water must be changed in time, and at the same time the condition of the seeds must be carefully observed. Once the seeds show white sprouts, they can be sown.
4. Maintain density
The sowing density must be reasonable. Generally, 100 kg of seedlings are needed per mu. When sowing, the seeds can be mixed evenly with fine sand and then spread, and after sowing, cover with about 0.5 cm of fine soil.
5. Management during the seedling stage
When celery seedlings have grown out, water and fertilize appropriately. If weeds are found in the soil of the planting site, pull them out in time. If the temperature is too high, remove the film in time; when the temperature is low, some plastic film can also be appropriately covered to help the seedlings grow and develop.
