Common cultivars of celery are generally two kinds of celery and parsley. The petioles of this celery are relatively thin, while the petioles of the parsley are relatively wide and thick. The petioles are often divided into white and cyan. The white leaves are relatively small and hollow. The growth cycle is short and the quality is good; while the cyan is tall and strong, and the yield per plant is large, it is easy to produce high yield, so it is necessary to select the variety according to the actual situation.

2. Soaking seeds and germination
Before sowing, soak it in water for about 24 hours, then wash it with water, wrap it in gauze, and then put it into the refrigerator in the refrigerator to germination. Of course, the leaf can be suspended in the well 40 cm. It needs to be cleaned once a day. Then wait for about 50% of the seeds to be white, you can plant.

4. Colonization
6 to 7 days before planting, the sunshade net needs to be removed. Fertilizer can be applied once a week before transplanting the seedlings.

Generally, transplanting can be carried out after 4 pm on a sunny day, and it is necessary to pay attention to the depth of colonization to avoid not revealing the root system and not burying the heart leaf. And ensure that watering is done immediately after planting to ensure live plants.
5. Water and fertilizer management
After cultivation, it is necessary to fertilize the field. After 10 to 15 days of planting, it is watered several times with small water, and 5 to 10 kg of carbon-based fertilizer can be applied in time. Then it can be used for 20 days or so. The root is derived downward. When entering the period of vigorous growth, it is necessary to keep the soil moist, and topdress the second time, the same as the first top dressing, and maintain the habit of watering while frying, of course, the whole process needs to be based on nitrogen fertilizer, remember not to use human feces. When the urine is used for watering, the sunshade is prone to rotten roots or rotten hearts.
6. Pest control
In the process of growth, it is necessary to prevent the pests and diseases of celery. Generally, celery needs to prevent spot blight and spot disease. It can use 75 times of methyl thiophanate 100 times solution and 70% of carbendazim 600 times. Alternate use of liquid; to prevent aphid damage, you can use 40% of dimethoate 100 times solution, which ensures the growth process to prevent pests and diseases.
