How to pick up celery seedlings in summer and autumn
In the celery seedlings, there are often problems such as slow seedling emergence, low germination rate, and irregular emergence. Therefore, the following points should be made on the seedlings: soak the seeds, soak the seed in 48°C hot water for 30 minutes before sowing, and then soak in the cold water for 12 to 14 hours, then rinse the seeds and drain them, then put them in a wet cloth bag. Place it 30cm away from the well surface or in the refrigerator. The temperature is preferably 15 to 20°C. It should be washed once a day. When 50% of the seeds are broken and germinated, they can be sowed. Sowing and sowing seedbed should be selected for convenient irrigation, soil loose, fertile land, 70 square meters seedbed per acre field, sowing 150 grams. Seedbed tops must be fine, broken and flat. The seedbed should be soaked with water before sowing, then sown uniformly, covered with 3 to 5 cm of nutrient soil after sowing, and finally covered with a sparse layer of straw. After sun-shading and rain sowing, cover the shade net. Always sprinkle water before emergence to keep the seedbed moist and prevent dry shoots.
