I. Variety selection Selection of high-quality, disease-resistant, wide-adapted, solid varieties, such as the celery class Jinnan real celery, Shimura celery, hardcore celery, etc., celery class high Utah, Ventura, Florida 638 and so on. Second, nursery According to cultivation season and methods, nursery can be done in Yangshuo, plastic arch, solar greenhouse, and open field. Seedlings in open fields must have rain, insect and shade facilities. 1, with the amount of seed: 80-meter per acre. 2. Seed treatment: Soak seeds in 20-water for 16-24 hours. After rinsing, use 1 bottle of Chunyu No. 1 to dip 50 kg and dip for 2 hours to help break the dormancy. . 3. Pregermination: Wash the soaked seeds, spread them a little to dry them, wrap them with a damp cloth and place them on the 15-places, and rinse them once every day with cold water. After 4-5 days, when 60% of the seeds germinate, You can sow. Third, nursery bed preparation 1, beds of soil preparation: the use of fertile garden soil and fully rotted sieve manure mixed in a ratio of 2:1, plus three yuan compound fertilizer per cubic meter. Spread the soil into the bed with a thickness of 10 cm. 2, bed soil disinfection: 50% of carbendazim WP and bacteria aseptic mix 10:1, or 25% metalaxyl WP and 70% mancozeb WP according to 9: 1 Mix, use 8-square meter per square meter, mix with 6-screened fine soil, soak 2/3 on the bed, and cover 1/3 of the seeds. 3, seedbed construction: open field nursery should choose high landform, drainage and irrigation convenience, good water retention and fertility of the plots, fine soil preparation, flat flat do flat, ready for sieving fine soil or medicinal soil, for sowing time. In order to control the growth of weeds during seedling stage, 48% trifluralin can be used before sowing. Each acre is sprayed with water on the surface of the loquat, and 4-5 cm deep is cultivated immediately after application to mix the drug with the bed soil. , Do you know when you are flat? Can also be used before sowing with 25% of herbicide ether emulsion per acre, watered 30-50 kg, evenly sprayed on the surface. Fourth, sowing 1, sowing date: summer celery late March to late April, autumn celery from late May to late June, greenhouse celery from early July to late July. 2, methods: pouring foot bottom water, water infiltration after coating a layer of fine soil (or medicine soil), the seeds spread evenly on the bed surface, cover fine soil (or medicine soil) 0.5 cm. V. Seedling management 1. Temperature: Nursery seedlings, suitable temperature within the seedbed is 15-. 2, shade: open field nursery, after the sowing in the hot season to use shade nets, curtains and other shade sheds to set up, not only to cool the sun, but also to prevent rainstorm washed seedlings. After the seedlings are released, the awnings are gradually removed. 3. Thinning: When the first true leaves of the seedlings are unfolded, the first time the seedlings are planted, the dense seedlings, the diseased seedlings and the weak seedlings are removed, the seedlings are separated by 3 cm squares, and the field seedlings are removed from the field weeds. 4, water and fertilizer: seedlings to keep bed soil moist, water pouring. When the seedlings 2-3 true leaves, combined with watering, topdressing urea 5-10 kilograms per acre, or 25 kg of foliar spray with colored zinc on the water, or 0.2% urea solution foliar fertilizer. 5, strong seedlings standard: seedling age 60-70 days, plant height 15-20 cm, 5-6 leaves, dark green leaves, developed roots, no pests and diseases. Sixth, soil fertigation Combine site preparation, high-quality rotten manure per acre, urea, superphosphate 30, potassium sulfate, and cola 4. After that, I will do it flatly. Seventh, planting 1, the planting period: the former to non-Umbelliferae vegetables is appropriate, summer celery from mid-May to mid-June, autumn celery from late July to mid-August, greenhouse celery from early September to late September. 2, the method of colonization: in the pod according to the spacing required to open the ditch planting, a hole per plant, soil to cover the short stem to reveal the heart and leaves is appropriate, edge planting side seal ditch flat rake, then watering. If the seedling is too tall when planting, the upper petiole can be cut off at 15 cm. 3. Density: This celery category: 30000-55000 strains of spring and summer celery per acre, 13-1510-lines of plant spacing, 22000-37000 strains of autumn celery, 15-2013-row spacing, and 9000-13000 strains of celery. Plant spacing 25-3020-25 cm. VIII. Management after planting Intertillage: After planting till ridge closure, cultivating 3-4 times, cultivating soil with cultivating soil and clearing field weeds. After 7-10 days of easing, seedlings are regarded as growing conditions. 2, water and fertilizer (1) Watering. The principle of watering is to keep the soil moist, and to ensure the moisture supply during the period of strong growth. After planting l-2 days, pour water once, and then if the temperature is too high, you can pour water to cool and stop watering during the seedling stage. (2) Dressing. Plant height 25-, combined with water, topdressing urea, potassium sulfate per acre. 3, temperature and humidity. The suitable temperature for the slow seedling growth period of celery in the solar greenhouse is 18-, and the suitable temperature for the growth phase is 12-. The temperature at the later growth phase can be maintained above. Celery has high requirements for soil moisture and relative humidity, but it must be released immediately after watering. (3) spray fertilizer. Celery is a boron-rich crop, and the lack of boron affects the yield and quality. Spraying 1500 times of color boron will increase production significantly. 9. Pest Control The use of each pesticide species must strictly comply with safety intervals. 1, physical control: First, hang silver gray plastic film to avoid maggots, greenhouse vents with nylon net yarn pest control. The second is the trapping of whiteflies and locusts with yellow plates, using 60 rectangular cardboard, painted with yellow paint, and then applying a layer of engine oil, hung on the top of the plant, 30-40 pieces per mu, when the yellow board is covered with white powder. For cockroaches and aphids, apply oil once more. 2. Pharmaceutics control diseases: The dust protection method and the smoke method are preferred for the protection place. Spraying can also be used for prevention and control in dry and sunny weather. Pay attention to rotation and rational mixing. (1) spot blight Smoke agent shed: Use 45% of chlorothalonil smoke agent or iprodione smoke agent, per acre, scattered 5-6 to ignite, fumigation overnight, once every 9 days. Chemical control: Spray with 58% Saifu or 50% carbendazim or 50% sulco wettable powder 500 times, spray once every 7 days. (2) Blight Smoke agent shed and dust control: See spot blotch. Chemical control: Spray 50% carbendazim WP 800 times, or 47% Garinon Wp 500x, or 58% Serif, 50% thiophanate-methyl WP 500x Spray, spray once every 7-10 days, spray twice. (3) Soft rot. The diseased plants were found to be excavated in time and disinfected with lime to reduce or suspend the watering; at the beginning of the disease, the spraying bacteria were aseptically 1500 times liquid, or they could be killed or neopentomycin 2500-3000 times liquid, separated every 7-10 days. Times, 2-3 times in a row. 3, pesticide control pests (1) Locusts. With 15% poisonous ear 1200-1500 times, or 10% imidacloprid wettable powder 1500 times, 6-7 days spray once, continuous 2-3 times. (2) Hey. Sprinkle bait control: first bait (grain, wheat bran, bean cake, cotton cake or corn crumb) saute, and then mix with 90% trichlorfon crystals 30 times, increase the amount, mix tide for Degree, 1.5-per-mu application, withdrawal in the evening without wind and heat.
