Celery food value and high yield and high efficiency cultivation techniques
Celery, also known as blue duck celery, parsley, red celery, Shuiying, wild celery, etc., is native to the Mediterranean region and is called watercress in the swampy area. It is called dry celery in the dry land. Its roots, stems, and leaves are Edible. In China, it has been cultivated for more than 2,000 years and is cultivated all over the country. Its nutrient-rich, and medicinal effects, deeply loved eating. My annual planting area is about 267hm2. Now we introduce its food value and high-yield and high-efficiency cultivation techniques as follows:
1 food value
Celery is a health vegetable that people like very much. Each 100g contains protein 0.6g, carbohydrate 2.7g, dietary fiber 0.9g, folic acid 29mg, calcium up to 152mg, calcium content is the highest in vegetables. Another phosphorus content of 18mg, potassium 163mg, sodium 517mg, vitamin C 6mg, selenium 0.6 滋 g, carotene 0.1mg and other more than 20 kinds of nutrients. At the same time, celery has the effects of diuretic, sedating the central nervous system, lowering blood pressure and cholesterol concentration in the blood, reducing gastric ulcers, aiding digestion, inhibiting protein saccharification, relieving arthritis, eliminating fatigue, promoting gastric secretion, increasing appetite and cramping, etc. Helps to treat diabetes, retinopathy, and has a certain weight loss fitness effects. Can be cold, cooked, fried, etc., can also be steamed stuffed buns, dumplings, dumplings and other snacks. The ascorbic acid content of celery leaves is higher than that of other parts, and celery leaves should be eaten together when consumed. The iron content of celery is high, and patients with iron deficiency anemia can often eat. People with high blood pressure and high blood lipids should eat regularly. Since celery can inhibit protein saccharification and eliminate free radicals in diabetic patients, it is very suitable for diabetics to eat regularly.
2 Cultivation Techniques
2.1 Variety selection
"Shangnong Yuqin" is suitable for all seasons in Zhejiang Province. The variety has fast growth, few tillers, coarse stems and low fiber content. Good quality, crisp, delicious, no bitter taste. The petiole is hollow, the heart of the leaf is golden green, the commodity is good, and the yield is high. The average yield is more than 30% higher than Huang Xinqin and the economic benefit is good. About 60 days after transplanting, they can be listed one after another.
2.2 Sowing seedlings
Seedlings are planted in early July. Due to more rain and more temperatures in summer and autumn, they are prone to guilt. Therefore, it is necessary to select the fields with good drainage and fertility. Apply base fertilizer before planting so as to keep the seedbed well. Early autumn when the celery is sown at high temperature season, the seeds must be treated at low temperature by soaking the seeds at room temperature for 12-24 hours, then washing with fresh water, removing the seed coat, washing and drying, and wrapping with a damp cloth. Refrigerate room below °C for 15~16 hours, then germinate in a cool and ventilated place to keep moist. Wait until 70% of the seeds germinate and sow. The sowing rate of 667m2 is 100~150g. After sowing, shade nets and rainproof sheds are used to cover nursery.
2.3 Seedling cultivation
After sowing, the seedbed should keep the soil moist and be conducive to the emergence of celery. After the emergence, the fertilizer should be poured every 15 days or so. The 667m2 of urea 250g, superphosphate 250g, potassium chloride 100g, and water 100kg should be mixed and poured; When there are 2 to 3 true leaves of the seedlings, the seedlings are planted once and the seedling distance is about 7 cm. After the planting, it is still covered with shade nets and weatherproof sheds. The coverings cover the night and the rain exposes the seedlings to make the seedlings strong.
2.4 timely planting reasonable dense planting
When the young plants were transplanted in open field in about 55 days and from late August to early September, how to control pests and diseases after apple harvesting had 3 to 5 true leaves and a plant height of 9 cm was the best time for planting. Transplanting spacing 8cm, plant spacing 7cm, transplanting density 85000 / 667m2.
2.5 Fertilizer Management
Except for basic fertilizer applied before sowing and planting. Before transplanting, generally 667m2 organic compound fertilizer 200kg plus 45% imported Norwegian compound fertilizer 50kg for deep application of base fertilizer. Daejeon planting logistics and fertilizer facilities. In mid-September, 667m2 applied 46% urea 20kg; in early October, 45% of Yangfeng compound fertilizer was applied 30kg; after transplanting, it was necessary to irrigate half ditch water to protect the seedlings 1 or 2 times, which is conducive to the survival of seedlings.
2.6 Pest and Weed Control
Insect pests in the whole growth period mainly control aphids, and diseases mainly prevent stalk rot. Weeding: 667m2 can be sprayed with Shida 50ml watered 35kg spray before weeding; control aphids: 667m2 sprayed with 10% imidacloprid 60g watered spray 40kg; prevention of stem rot: 667m2 water with a dagger 50g 50kg spray.
2.7 timely harvest
Celery is a product of fresh stems and leaves, timely harvesting and marketing is the main method to achieve early spring cultivation, but also an important part of high yield and high efficiency. Generally, in early November, when 11 leaves and a plant height of 50cm or more were harvested and marketed, the harvest period was about half a month.
2.8 Production and Economic Benefits
Through years of practice, "Shangnong Yuqin" generally produces 667m2 of around 3,500kg, with an output value of more than 6,500 yuan. After deducting seeds, fertilizers, pesticides, agricultural films, agricultural machinery, contracting fees, and labor costs, the total cost is nearly 2,000 yuan. The net profit is about 4,500 yuan.
