1. Seedling management Seedlings are seedlings at the seedling stage to properly manipulate the fertilizer and promote the decomposition of the celery roots and leaves. Chunxi celery does not need slow seedlings. After planting, it must attack the fertilizer and water to promote growth and avoid premature twitching. 2. Capping shade net, insect net Celery likes cool, and it is necessary to cover the shade net after the planting in the summer and autumn to avoid the heavy rain. Sunshade nets should be covered in sunny mornings, uncovered at dusk, and uncovered on cloudy days. When it rains, they must be covered with plastic film to block the rain. Insect nets are stamped to prevent the damage of milkflies and locusts and to convey the virus. 3. The soil exposed heart and seedlings After planting and sprinkling, when the surface is slightly dry, look through the rows of wheat seedlings that have been buried in the soil or the wheat seedlings have been washed down by the water. Be careful to remove the soil from the heart and leaf, and then straighten the seedlings. 4. Temperature regulation After the celery is colonized, the daily temperature is maintained at 20-25°C, 10-18°C at night, and the ground temperature is maintained at 15-23°C. The night temperature should not be lower than 5°C. To cultivate the northeast region, it is necessary to shade and cool the early stage, and to adopt insulation measures later to avoid freezing damage. The natural light conditions of celery in autumn and winter can satisfy the growth and development requirements of celery. The early light is strong, the plant grows vigorously, and the lateral growth is the main; the late light is weak, which is beneficial to the longitudinal growth of the plant. The suitable temperature for protected seedlings of Celery is 18-22°C, and the suitable temperature for growth is 12-18°C. The growth temperature should be kept above 5°C. 5. Fertilizer management Since celery grows for a long period of time, it requires a large amount of fertilizer. In addition to the application of base fertilizer, it is necessary to apply fertilizer according to the needs of different growth and development stages. Top dressing should be applied thinly, generally 10 kg of urea and 10 kg of potassium sulfate. The growth period of leafy clumps requires the largest amount of fertilizer, 25 to 30 kg of ammonium sulfate, 5 kg of potassium sulfate, and 10 kg of superphosphate per mu. Together, during the whole growing period, appropriate amounts of calcium and boron fertilizers are also applied. The calcium deficiency of parsley is easy to attack heart rot, and the lack of boron is prone to produce burrs in the outer leaves of the early period, and the petioles in the later period are prone to chapped. Can be combined with sprinkler per acre topdressing 700 grams of borax, superphosphate 10 kg. In the later stage, foliar spray of 0.1% urea, 0.2% borax, and 0.1% potassium dihydrogen phosphate solution are also available. Topdressing is necessary to match with the sprinkler in order to fully utilize the fertilizer effect. The top-dressing sprinkling was suspended 15 days before harvest to reduce the nitrite content of the product and facilitate storage. Celery is better than water, planting water after planting, slow seedling watering in time. The principle of watering during the growth period is "see dry see wet". After the plants "set their hearts", they poured water once every 5 to 6 days. "Western celery quinoa, fish pond", celery growth can not be short of water, otherwise its growth rate slowed down, fiber increased, quality deteriorated, and production value decreased. Sprays should be controlled in late autumn and winter. 6. Timely tillage weeding After seeing dry earth, seedlings on the ground promote rooting. Combine loose soil for weeding. Celery grows slowly in the early stages and is extremely vulnerable to weed damage. In particular, with the continuous rainy weather, weeds grow quickly and damage is exacerbated. In the early stage of growth, the distance between rows of plants is large, which facilitates manual weeding. Can also be used to remove weeds in the weeds at the 3 to 5 leaf stage. The late plant lines can be manually removed at any time. It is common to combine weeding with cultivators before top dressing. Since the root system of celery is shallow, the cultivator should be shallow, and it is only necessary to reach the weeding ripping soil. It should not be too deep to avoid injury and affect growth. 7. Plant Management Remove the tiller leaves in time, and close the stems and leaves with a tear film. During the growth of celery, it is prone to seizures (expulsion), and the tiller leaves grow faster than this leaf. If it is allowed to grow, it will directly affect the quality and output value of celery. Therefore, it is necessary to remove the tiller leaves in time before the plants “set their heartsâ€. 8. Spray growth regulator It can be sprayed twice with 50 mg/kg gibberellic acid about 20 days before the harvest, which can promote the growth of celery, avoid plant aging and improve the quality of celery. In the face of drought, low temperature, weak light and other adverse climate, spraying growth regulators will show a better effect.
