In Shouguang City, the Wenjia Sub-district Office and some villages in Daotian Town have the habit of cultivating celery, and they have rich experience in planting celery. The following is a summary of the technical points concerning the cultivation of celery by the writer. .
Precision seedbed
Choose a loose, fertile garden plot to make a seedbed with a bed width of 1 to 1.2 meters, a ditch depth of 10 to 15 centimeters, and a flat bed surface. Sowing in August. The seeding rate is 400 grams seed per acre seedbed, and the ratio between seedbed and field is 1:8. Low-temperature germination before sowing, soak the seed with water for 12 to 24 hours, rinse with water, remove the epidermis, and dry the moisture on the surface of the seed, and wrap it in a refrigerator and cool it in a cool cloth at room temperature for 15 to 16 hours at 5°C. After germination in the room, keep it moist, and sow 50% of the seeds after germination and whitening. The foot water should be poured first, then evenly sowing, sowing depth of 1 ~ 1.5 cm.
Post-broadcast management
When the temperature is high at noon during the day, straw mats are used to prevent sun exposure. In heavy rain days, straw mats are also needed to prevent rainwater from flushing. Seedlings are sprinkled and sprinkled with water to prevent drought. Can be combined with watering, mixed with water and manure to increase nutrient supply at seedling stage. After implantation, imidacloprid 1 bag was used per acre seedling bed, 10 kilograms of water was sprayed with fine mist, and locust infestation was prevented.
Transplanting at the right time
When the seedlings grow to 5 to 6 true leaves, the seedlings can be planted at a height of 10 cm. Planting should be selected ventilation, sunny, loose and fertile soil plots, before planting deep-drying whitening, full base fertilizer, the general maturity of each seedling decomposed organic farmyard fertilizer 2 to 3 cubic meters, superphosphate 50 kg, potassium sulfate compound fertilizer 10 Kilograms of urea and 8 kg of urea. Apply enough base fertilizer to plow till the fertilizer and soil are fully mixed. If it is a large-scale field cultivation, we can also wet the field and wet the fertilizer. Spread the fertilizer evenly. After 5 days, plant the grass directly on the field. Can save a lot of manpower.
Fertilizer management
Early application of fertilizer, to promote the rapid growth of stems and leaves, 15 to 20 days after transplanting urea applied 10 to 15 kg per acre. In the later period, it is always pouring fertilizer. During the growth period, spray 2 to 3 times of soluble boron or superphosphate leaching solution to prevent petiole cracking and rotten heart, to prevent yellowing of the petiole in the later period, and to spray 1 time before 10-15 days before harvest, which can effectively improve the quality.
Pest control
Locusts, such as spraying with anti-inferiority. Leaf spot and spot blight, controlled with chlorothalonil or anti-virus warts. Virus disease, with phytosanitary spirit, antiviral No. 1, virus A and other prevention and treatment. Soft rot, controlled with agricultural streptomycin sulfate or neomycin.
