When was the celery sown? What are the main points of planting methods?

Small celery, also known as water celery and river celery, is a kind of pollution-free green vegetable with both medicine and food, which mainly grows in swamps or wetlands. Small celery growth period is relatively long, generally autumn, winter and spring three seasons can be harvested, there is no time limit, the practice is also more, can stir-fry can also be cold, and so on. Let's see when the celery was sown. What are the main points of planting methods?

When was the celery sown?

Small celery can choose spring, summer, autumn three seasons for sowing, seedling and so on.

1. Sowing in spring: March is the suitable sowing time in the Yangtze River basin. In the north, seedlings are raised in protected areas from March to March, planted in open fields from March to April, and harvested from May to July.

2. Summer sowing: raise seedlings in the open field after breaking frost in spring, plant in June to early July, and harvest in August to September. However, the summer temperature is relatively high, the growth of celery is not good, easy to be attacked by diseases and insect pests, not suitable for large-scale planting.

3. Sowing in autumn: it can be cultivated in the Yangtze River valley and the south, sown from September to November, and harvested from December to April of the following year. In the north, it is sown and raised seedlings from June to early July, planted from August to early September, and harvested from October to November. In the Yangtze River basin, the seeds were sown from early July to early September and harvested from October to December, while the late sowing ended with winter celery harvested before bolting in March to April the following year.

Second, what are the key points of small celery planting methods?

1. Temperature requirement

Celery is a cold-tolerant vegetable, the growth temperature varies in different periods, and the suitable temperature for growth during seed germination is about 15 to 20 degrees Celsius. The growth temperature during the nutritional period is between fifteen and twenty degrees Celsius. Small celery is not resistant to high temperature, more than 26 degrees Celsius will appear aging, poor quality, many diseases and insect pests, so we generally do not plant in summer.

2. Lighting conditions

The growth of celery is not very demanding for light, and it can grow even in the shade, but it grows better in places with plenty of light.

3. Fertilizer

The growth of small celery is mainly to absorb nitrogen fertilizer, increasing the amount of phosphorus and potassium fertilizer can help the growth of seedlings and improve the length and quality of petiole.

4. Moisture

Small celery needs a lot of water during the vigorous growth period, so it should not be too dry to keep the soil moist.

5. Soaking seeds to accelerate germination

Small celery seeds should be soaked and germinated before sowing. Soak the seeds in cold water for two to four hours. After washing, dry water is controlled and placed in an environment of 15 to 20 degrees Celsius to accelerate germination. During the budding period, the seeds should be washed with clean water regularly to increase the air permeability and maintain humidity. Usually within a week, the radicle can be exposed for sowing.
