Celery has been planted for a long time. For the warmer south, celery can be planted all year round, and it can be planted in the north in spring, summer and autumn.
Celery should be planted in spring, and seedlings should be raised in June 5438+ 10, sown in March and harvested in May and June.
Celery should be planted in April-May, June-July and harvested in August-September in summer.
Autumn celery is cultivated in June-July, planted in August-September, and harvested in10-165438+10.
In the warm south, you can sow directly in September-65438+1October and harvest from June-February to March-April of the following year.
Celery 1 Planting Precautions and Variety Selection
Celery can be divided into celery, celery and celery. Different kinds of celery have different requirements on planting time, soil and growing environment, so we should choose suitable varieties according to our local climate and soil environment.
If local irrigation is inconvenient, you can choose celery planting;
If the local cold is early, you can choose celery varieties with high cold resistance.
2. Celery seedlings
Before raising celery seedlings, the seedbed should be prepared, and then the seeds should be soaked and germinated.
Celery likes fertile soil, which is convenient for irrigation and cool. After selecting the seedbed, base fertilizer should be applied first. The base fertilizer can be fully decomposed farm manure or compound fertilizer, and an appropriate amount of pesticides can be added to kill insects in the soil. Then soak the seeds in clear water for 48 hours, then take out the seeds and put them in a cool and humid place to accelerate germination. Generally, most celery seeds have germinated after 3-4 days, and celery can be planted after germination.
After celery is sown, spray the surface of the border with a watering can to promote celery germination. If it is planted in winter, it can be covered with plastic arch shed after sowing. If it is planted in summer, it should be covered with a sunscreen net to prevent exposure to the sun.
Celery has a great demand for water at seedling stage. Generally, watering can is used once every evening. After all celery seedlings come out, topdressing should be done every other week. Be careful not to use too much fertilizer, which will easily burn celery seedlings.
3, celery colonization
Celery can be planted 50-60 days after it grows to 12- 15 cm. Pesticides should be sprayed and watered in advance before planting to avoid damaging the roots of celery seedlings.
Celery should be planted in clusters, with 4-5 plants per cluster, cluster spacing 1 cm and row spacing 15-25 cm. Before celery survives after planting, water it every morning and evening to observe the survival rate of celery. Once dead seedlings appear, they should be replenished in time.
After celery survives, management will be simpler. When the soil is dry, it can be irrigated in the morning and evening when the temperature is low. Be careful not to be flooded, which will easily lead to celery root rot. Drainage and irrigation should be carried out in time in rainy season.
4. Prevention and control of pests and diseases
Celery has fewer pests and diseases, so it is necessary to be careful not to be bitten by pests in the soil during celery seedling stage, so the soil should be insecticidal before seedling raising and planting. When celery enters the prosperous period, leaf blight, leaf blight and aphids will occur, and fungicides and pesticides can be used to prevent and control it in time.
Celery is widely used in our life. Ms Amy, who is losing weight, likes to use celery to juice and scrape oil. Northerners like to wrap jiaozi and steamed buns with celery. Celery can also be stir-fried cold, and celery leaves can also be made into celery cakes cold.
