Celery is a vegetable with high nutritional value, rich in protein, carbohydrates, dietary fiber, vitamins, calcium, phosphorus, iron, sodium and other more than 20 kinds of nutrients. The content of protein and phosphorus is 1 times higher than that of melons, and the content of iron is 20 times higher than that of tomatoes
How to Plant Celery Seeds1. GerminationThe sowing time of celery should be chosen in the middle and end of June. Before sowing, soak the seeds in clean water for 12 to 24 hours, scrub them, then place the polished seeds in an ventilated place for a few minutes and wait until the seeds run out. If the surface is dry, it can be used. Wrap the seeds in a damp towel and place them in a warm environment. Take a damp towel and sow until the seeds show buds.2. SowingSow seeds into the soil. The soil should be watered in advance. After sowing, the seeds should be covered with a thin layer of soil, paying attention to keeping the soil moist. In general, water every 1 to 2 days. When the seedlings are 12 to 15 cm long, you can apply manure. Generally harvested around October.
Requirements for environmental conditions1. Temperature: Celery is a cold-tolerant vegetable, requiring relatively cool and humid environmental conditions, and does not grow well under high temperature and drought conditions. Celery has different requirements for temperature conditions in different growth and development stages.The optimum temperature during the germination period is 15-20°C, lower than 15°C or higher than 25°C will delay germination or reduce the germination rate. Under suitable temperature conditions, it can germinate within 7 to 10 days. The seedling stage has strong adaptability to temperature, and can withstand low temperatures of -4~-5℃.Seedlings can be vernalized in 10 to 20 days under low temperature conditions of 2 to 5°C. The optimum temperature for seedling growth is 15~23℃. Celery grows slowly during the seedling stage, and it takes about 60 days from seeding to growing a leaf ring. Therefore, celery is mostly cultivated by seedling transplanting.The period from planting to harvest is the period of vigorous vegetative growth of celery, and the optimum temperature for growth in this period is 15-20°C. If the temperature exceeds 20°C, the growth will be poor, the quality will decrease, and the disease will be prone to disease. The adult celery plant can tolerate low temperature of -7~-10℃. The reason why autumn celery can produce high yield and high quality is because the autumn temperature is most suitable for the nutritional growth of celery.
2. Soil: Celery has strict requirements on the soil. It needs loam or clay loam that is fertile, loose, well-ventilated, and strong in water retention and fertility. Sandy soil and sandy loam soil are prone to lack of water and fertilizer, causing celery petioles to become hollow.
3. Nutrients: Celery requires more complete fertilizer. In the nutrient composition of fertilizer, since celery is mainly edible nutrient organs, it has a greater demand for nitrogen. Lack of nitrogen, phosphorus, and potassium at any stage will affect the growth and development of celery, and the impact is greater in the early and late stages, and nitrogen deficiency has the greatest impact. More fertilizer is needed in the seedling and later stages.
4. Moisture: Celery is a shallow-rooted vegetable, with weak water absorption capacity, weak drought tolerance, large evaporation, and stricter water requirements. After sowing, the bed soil should be kept moist to facilitate the emergence of seedlings. During the vegetative growth period, the soil and air should be kept moist, otherwise the thick-walled tissue in the petiole will be thicker, the fiber will increase, and the plant will be easy to hollow and age, which will reduce the yield and quality. In cultivation, water should be supplied according to soil and weather conditions.
5. Light: Celery is shade-tolerant and needs to be covered with shading nets before emergence. Medium-intensity light is preferred during the vegetative growth period, and sufficient light is needed in the later period. Long-day light can promote the differentiation of flower buds in the seedling stage of celery and promote bolting and flowering; short-day light can delay the flower formation process and promote vegetative growth. Therefore, celery seeding in a suitable time, maintaining a suitable temperature and short-day treatment are important measures to prevent bolting.
