Planting techniques of celery

Today, I would like to share with you some techniques for growing celery on the balcony. Celery is a vegetable variety that our people like to eat. Celery is a high-fiber food, which produces a kind of lignin or intestinal fat through intestinal digestion. this kind of substance is a kind of antioxidant, often eat celery, especially celery leaves, it is very beneficial to prevent hypertension, arteriosclerosis and so on, and has adjuvant treatment effect. Celery like cold, humid climate, is a semi-cold-resistant vegetables; not resistant to high temperature. The lowest temperature of seed germination is 4 ℃, and the optimum temperature is 15 ℃ 20 ℃. The seedlings can withstand the low temperature of-5 ℃. The seedlings with 3-4 leaves go through the vernalization stage at the temperature of 2-10 ℃. The optimum temperature for vernalization is 12-13 ℃. Hangzhou area can be cultivated in spring and autumn, mainly in autumn, and the cultivated varieties are Hangzhou Qingqin and Huang Xinqin.

Cultivation method: celery is suitable for sowing and raising seedlings directly with seeds. Generally, celery is cultivated in the greenhouse from February to March, planted in late April, harvested from late May to early July, cultivated in autumn, sown and raised seedlings from mid-June to early July, spring planting from mid-August to early September, and harvest from October to November. Soaking seeds and accelerating germination can be carried out 7-8 days before sowing, and the seeds can be sowed after the seeds are budded. Wet sowing method is mostly used, that is, the bottom water is poured first, and then mixed with sand. After sowing, the soil cover should be thin and even. generally, a small amount of water can be poured every 2 days in the morning and evening until the seedlings come out. Sowing in spring and autumn can not be covered with a shade. Boil small water frequently to facilitate seedling emergence. There should be no shortage of water during the growth period, and water should be watered for 5-7 days. When the temperature is low in spring, the amount of water should be small, the watering interval should be long, and more water should be needed in the peak growth period, so it is necessary to keep the soil moist. Celery needs more nitrogen fertilizer, so it is necessary to apply fertilizer in time after a week of seed germination, and then no longer apply fertilizer in the process of growth.

Harvest: harvesting before bolting or harvesting with split leaves can reduce the harm of early bolting and do not harvest when the bolting plant is old.
