Annual cultivation of celery
First, change the rules of spring cultivation in the middle of March nursery, planting in late May, August harvest; autumn cultivation in late June nursery, planting in mid-September, harvest in late November; winter cultivation in mid-September, 12 Planted at the end of the month and harvested in late March. After the harvest, winter celery sheds can be used for 2 months. During this period, rapeseed, Chinese cabbage and other fast-growing vegetables can be planted for short-term crop rotations to prevent diseases and insect pests from increasing due to long-term continuous cropping. Second, sowing nursery 1. Site preparation: Spring and winter planting materials to Jianye, Qiujian to Jianbei from north to south. Seedlings should choose high-lying land that can be easily planted. Mushi rotten organic fertilizer more than 3,000 kilograms, made of 1.2 to 1.5 meters wide flat rake, sorghum to be flat, no major slag. 2. Sowing: The day before sowing, the seedbed is filled with bottom water. After the water penetrates, fine soil is sprinkled on the surface of the seedbed. Mix fine soil and seeds, spread evenly on the seedbed, cover soil 0.5 cm thick, spray 25% herbicide ether, 500-800 grams per mu. 3. Seedling management: After the emergence of timely cultivator weeding, spring pod nursery 15 to 20 days before sowing roast, after sowing at night to cover straw insulation. The temperature is maintained at 15°C to 20°C, and the temperature is lowered appropriately after emergence. The temperature is not higher than 20°C during the day and not lower than 8°C during the night. Spring nursery should prevent vernalization through the seedlings, the night temperature must be controlled above 8 °C. Qiuyu seedlings are in full bloom in summer, and attention is paid to shading after sowing. The late winter nursery should pay attention to insulation, prevent early frost, produce frost damage. Third, colonization in the seedlings grow 4 to 6 true leaves, age 60 to 70 days when planting. The seedlings were planted 2 to 3 days before planting, and the seedlings with thick leaves and developed roots were selected and transplanted on a sunny morning. Plant spacing 8 to 10 centimeters, spacing 18 to 20 centimeters, planting depth to not bury the heart of the leaf, should be shallow should not be deep. Spring eel is planted in late May, and water is poured after planting; autumn eel is planted in mid-September, covered with shade after planting; winter eel is planted in late December, covering the film to warm up. Fourth, field management Seedling management: seedlings should be properly controlled to control the fertilizer and seedlings, and promote root and leaf differentiation. Spring do not need to slow seedlings, planted after the attack on fertilizer, promote growth. 2. Fertilizer and water management: After 7-8 leaves of celery grow into a vigorous growth stage, fertilizer and water should be increased at this time. Apply urea or compound fertilizer 10-15 kg every 15 to 20 days. 3. Temperature and light control: Before the middle of June, spring celery celery should be covered with straw to keep warm and reduce ventilation during the day. The grasshoppers were removed in late June, shade nets were placed on the film, and ventilation was increased during the day. During this period, more rain, it is necessary to timely clear the drainage channels in the field to prevent rain from entering the shed and causing rotten seedlings. Qiuyu will be covered with grasshopper insulation from late October to prevent freezing damage. In the event of a dark day in winter, it should be unveiled at noon.
