First, seedbed preparation. Choose a loose, fertile vegetable plot for the seedbed. Plants before sowing, 1000 kg per acre pig manure, 25 kg compound fertilizer, the seedbed made 1.2 meters wide rake. Second, processing celery. In mid-August, the robust, disease-free celery was cut into small pieces in sections, placed in a bamboo container, kept moist and clean, washed once a day, and rot leaves and old leaves were promptly removed. After 1 week, the celery sprouts were sown at a length of 1 cm. Third, nursery. The cultivating celery with good buds will be sown evenly on a bed that is irrigated with water, then the cover soil will be 0.5-1 cm thick, and generally about 250 kg of celery will be planted per acre. When the celery mu is as long as 2 centimeters in height, 1,000 kilograms of human fecal urine fertilizer or 10 kilograms of urea is applied per mu, and carbendazim or allergen solution is sprayed at the same time to prevent the celery rot. If it is found that locusts should be controlled in time. IV. Transplanting and post-planting management. In the middle and late September, when the celery grows to 5-6 leaves, it is transplanted with a spacing of 10 cm and a spacing of 3 cm. After the plants survived, 1,000 kg of diluted manure was applied per acre. After management, winter celery and spring celery are different: (1) winter celery. In early November, 5 kg of urea was applied per acre, and then the first bauxite was performed. It is advisable that the roots of the plants be exposed to the leaves of the plants. For the first time after 7 days of levitation, celery grows to 10-15 centimeters in height, and the second time is performed. After the second time the earth is finished, it will take 10-15 days to harvest the shoot celery. In case of poor market conditions, it may not be harvested for the third time, and then the third time, the soil will be harvested 10-15 days after the end of the soil. (2) Spring celery. In early January of the following year, 5 kg of urea was applied per acre. In early February, when the temperature stabilizes at 10°C, the soil will be soaked in the same way as winter celery. Fifth, pest and disease control. The main pests that injure bud celery are the aphids and cabbage caterpillars. Attention should be paid to the timely inspection of pests. Aquifers can be sprayed with 25% of fast-killing emulsifiable concentrate 30 ml per kilogram of 30-40 kilograms of water per acre. The main diseases of the harmful shoot celery are spot blotch and early blight, especially in the germination and nursery period. It can be sprayed with 50% carbendazim or 75% chlorothalonil per acre when the celery grows to 2 cm high. Prevention. China Agricultural Network Editor
