When celery was planted, it was impossible to plant and harvest on time in case of seedlings that were not neat. Second, fear of uneven growth, plant sizes, high and low, low yield, poor quality, not easy to sell. Third, fear of pests and diseases, causing losses. How can we overcome these difficulties in production? First, we must choose a good seed and cultivate a good seedling. In winter cultivation, cold-resistant, solid-tolerant, dark green varieties should be used. Such as Weifang Qingmiao solid celery, Jinnan real celery and so on. Whether it is winter or summer, the seeds must be soaked, washed, germinated, and then sown after the seeds are dewy. Select loose texture, fertile soil, deep soil layer to raise seedlings, strengthen fertilizer and water management at the seedling stage, dilute the ground with small water, apply thin fertilizer, and cultivate strong seedlings. Second, we must do a good job in land treatment before planting. Planted in winter, before planting, with full maturity farmyard fertilizer 80-100 per acre, evenly spread. At the same time, 100-150 kilograms of quick lime are applied per acre, shallow ploughs are used, fertilizer, soil and lime are mixed evenly, and then soil preparation is performed. Third, we must plant closely and plant large seedlings. The size of the seedlings is basically the same, and there are 3-4 leaf large seedlings planted. Row spacing is: 5 cm 8 cm, or 6 cm 7 cm, only one seedling per hole. In this way, the size of each celery can be basically the same. Moreover, the late leaves overlap each other and block the sunlight shining on the petiole. The petiole is not only long, but also bright and lustrous. Fourth, we must do a good job in field management. In winter, the shed film is pressed to avoid air leakage. In case of cold weather, double or multi-layer film is used to prevent freezing damage. At noon on a sunny day, the shed film was uncovered and the air was ventilated to reduce the humidity. Before planting ridges, pour watered manure for 2-3 times. After ridge sealing, apply urea solution once. One month after colonization, and one week before harvest, gibberellin (90%) was sprayed to promote growth. Per bag of gibberellin, summer spray against three sprayers, winter water spray against two sprayers. Fifth, we must scientifically prevent and treat diseases and insect pests. The diseases of celery during the seedling stage can be selected from chlorothalonil, phospho-aluminum, and Plycor and other pesticides. In winter, after the insulation of the buckle shed, smoked smoke agents such as chlorothalonil, sulferyl, and dichlorvos are used to fumigate pests and diseases. The effect is very significant.
