Celery is a cool and humid climate and it is a semi-cold vegetable; it is not heat-resistant. Drying can withstand short-term sub-zero temperatures.
First, the requirements of environmental conditions
1, the temperature: celery sex like cool climate, growth suitable temperature 16 to 22 °C.
2, light: celery vegetative growth stage is not strict on the light, the lower the light intensity requirements, under weak light conditions, still able to grow normally.
3. Soil: Celery is suitable for growing in sandy loam rich in organic matter.
4, moisture and nutrients: celery hi moist, so in the cultivation of soil to maintain adequate moisture; need a large amount of fertilizer, but because of weak root absorption capacity, it should be enough to apply base fertilizer in cultivation, and timely fertilizer To meet celery's need for nutrients.
Second, cultivation points
1. Variety selection: It is generally based on the early spring celery or yellow celery varieties with strong anti-reaction strength.
2. Seeding and Seedling Cultivation: In recent years, the seedlings have been mainly broadcasted. When the seedlings reach a height of 12 cm, they will be transplanted at a ratio of 1:2. The seedlings will be planted in an amount of about 1,000 grams per acre. The sowing date is generally set at 6 months. From late late to early July, due to the high temperature during this period, it is necessary to dip in the house to sow seeds after soaking. Soak in fresh water for 4 to 6 hours before draining, put in the freezer freezer, and then germinate in a cool place indoors until the seeds are white. After sowing in the finished bed soil. After sowing of celery in early autumn, it must be shaded and covered with shade nets and other coverings to reduce ground temperature, prevent water evaporation, and ensure seedlings.
3. Site preparation and planting: One week ahead of schedule, the soil will be ploughed and matured, combined with site preparation, 500 kg of organic fertilizer for Mushi and 50 kg of vegetable-specific compound fertilizer to fully mix with the soil to create a good aggregate structure and nutrient soil layer. , And do deep trench sorghum, can irrigation and drainage (in this case refers to the site preparation, also includes live seedbeds). When the seedlings grow to 12 cm in height, they can be transplanted on a cloudy or sunny day in the evening. The seedlings should be planted in the transplanting field, sun-shrouded after transplanting, or transplanted in a protective greenhouse, with a shade net. cover.
4, fertilizer and water management: celery needs a large amount of fertilizer, but weak root absorption capacity, it should be combined with watering, timely dressing, usually top dressing 2 to 3 times, each applying fertilizer urea 5 to 8 kg per 667 square meters, grasp the light Fertilizer application principle ensures a balanced supply of nutrients.
5, pest management: early autumn celery disease-based disease, can be used Amisite, pungent and other fungicides 1000 times dilution spray control. Insect pests are mainly aphids and can be controlled by highly efficient and low-toxic insecticides such as imele and imidacloprid.
6. Harvest: When the celery plant grows to 35 to 40 cm, it can be harvested and marketed. Early autumn celery live generally listed in mid- and late September. The celery transplanted in mid-to-late August is generally listed before and after the National Day. The output per mu is 1800 to 2100 kg, and the economic benefits are extremely valuable.
Celery with Pinggan heat, expelling wind and dampness, Chufan swelling, cooling blood to stop bleeding, detoxification Xuanfei, Jianweilixue, clearing the intestine, lungs and cough, lower blood pressure, brain sedative effect. Eating celery, especially celery leaves, is very beneficial for the prevention of hypertension, arteriosclerosis, etc., and has the role of adjuvant therapy.
