1. Seeding and seedling raising

The place suitable for celery growth must be a relatively cold place, and the soil suitable for celery cultivation must be fertile and loose, and there must be a good drainage system. When digging, we should lay a good foundation fertilizer and level the land as much as possible. Seedlings should be packed in bags, then tied and soaked in water for two days, then taken out of the water, which should have germinated after three or four days, and then taken to the ground for sowing.

2. Planting and planting

After the seedlings are all grown, you can start to pull out the seedlings and plant them. Plant the seedlings one plant at a certain interval, apply fertilizer for the first time, and use farm manure as much as possible.

3. Field management

After planting, don't think it's over. Before celery grows new roots, it needs to be watered every morning and evening, and the dead seedlings should be replanted in time. Fertilize again when all celery has grown new roots and leaves. Weeds in the field should be weeded in time to prevent absorption of nutrients in the soil.

Extended information:

Celery likes cold, cool and humid climate and belongs to semi-cold-tolerant vegetables; Not resistant to high temperature. Drying can withstand short-term low temperature below zero. The lowest temperature of seed germination is 4℃, and the optimum temperature is 15 ~ 2℃. The germination is delayed below 15℃, and hardly germinates above 3℃. The seedlings can withstand the low temperature of-5 ~-7℃, belonging to green vernalization plants. The seedlings with 3 ~ 4 leaves go through vernalization stage at 2 ~ 1℃ for 1 ~ 3 days. The cold resistance of celery is poor, and the seedlings are not resistant to frost. The suitable temperature for vernalization is 12 ~ 13℃.

It is native to the marshes along the Mediterranean coast and has been widely cultivated all over the world. Celery cultivation in China began in the Han Dynasty and has a history of more than 2, years. At first, it was only planted as an ornamental plant, and then it was eaten. After constant domestication and cultivation, it formed a slender petiole celery cultivation species, namely Benqin (China celery). This celery is widely distributed all over China, and Zunhua and yutian county in Hebei, Weixian and Huantai in Shandong, Shangqiu in Henan, Jining in Inner Mongolia and other places are famous producing areas of celery.
