Seedlings are raised in mid-December, and the seedling period is 7 days. In the seedling stage, there is generally no watering, and there is no need to topdress. Only when the drought is found, can the water be poured in the watering can, so that the seedlings grow slowly and avoid the lengthening.
Planting is first done on the ground for the application of base fertilizer. After the Spring Festival, before the vegetables fell to the ground, level the ground, make a 1 meter wide raft, evenly spread a layer of farmyard manure on the glutinous surface, 10 kilograms per square meter, re-turn it again, and prepare for planting. The second is to plant seedlings, each planting 6-7 rows, the hole spacing 8-10 cm, planted irrigation.
Management generally does not need to simmer the seedling water, and the heart leaves are loosened when they start to grow. The daytime temperature is maintained at 15 °C - 20 °C, 10 °C at night, when the plant has 5-6 pieces of large leaves, 20-30 grams of urea per square meter, while chasing and filling the water. After top dressing, the kneading surface is kept moist, and the temperature can be raised to 20 ° C - 25 ° C. The water is continuously poured several times, and the celery petiole is rapidly elongated to be harvested.
