How to grow celery? How to realize the wonderful Miao Zhuang of celery?

Generally, in spring, seedlings are raised in greenhouse from May 438 to February in June, sown in March to April, and harvested in May to July. In summer, the seedlings are usually planted in March-May, and the seeds are required to be soaked for 24 hours before sowing, and the interval is timely after emergence, and the plant spacing is controlled at about 2 cm. There is no need to cover the film when sowing in April, and the sunshade net should be covered before sowing and seedling emergence to help keep moisture. Seeding and seedling raising in autumn are generally carried out from early June to mid-July, sowing in late July and sowing in late August. Because the sowing time in autumn is in the high temperature season, the suitable temperature for celery seed germination is between 15-25 degrees, and it is difficult to germinate when the temperature exceeds 30 degrees, so it is necessary to sow at low temperature and accelerate germination. It is suggested that the plot with high sediment concentration, sufficient water and good water permeability should be selected as the low seedbed. In order to make the seedbed fertile enough, some farmyard manure can be properly applied to level the soil.

According to local climate, market demand, etc. Choose varieties suitable for planting and make the seeds germinate. Soaking with clear water before germination and fully stirring during soaking are beneficial for plants to fully absorb water. Seeds can germinate in a temperature environment after soaking for one day. The planting density must be reasonable. Generally, seedlings are required per mu 100 kg. When sowing, you can mix the seeds and fine sand evenly, and then spread 0.5 cm of fine soil. When celery seedlings grow, they should be properly watered and fertilized. If weeds are found in the soil in the planting area, they should be pulled out in time. If the temperature is too high, the film should be uncovered in time. If the temperature is low, some plastic films can be properly covered to facilitate the growth and development of seedlings.

High temperature in summer makes it difficult to raise celery seedlings. In order to improve microclimate, create suitable environmental conditions for celery growth, and lay a foundation for high-yield and high-quality production, some relevant measures must be taken when raising seedlings. Celery seeds are small, the stored nutrients are limited, the newly grown roots are few, and it is sensitive to soil moisture and temperature. The seedbed should be thick, with loose and fertile soil, rich organic matter content, good air permeability and water retention, convenient drainage and irrigation, and cool ventilation. Avoid continuous cropping plots to raise seedlings and avoid soil-borne diseases and insect pests. Celery is a cold-tolerant vegetable, which needs a cool and humid climate. The suitable temperature for seed germination is 15 ~ 20℃. The germination rate decreased above 25℃ and hardly germinated above 30℃. In summer, due to the high outside temperature, germination is difficult, so we can adjust measures to local conditions. The germination temperature should be controlled at 15 ~ 20℃ and 10 days.
