How to manage celery at the seedling stage? Latest technical method tutorial
Celery is a plant of the Apiaceae family, with a great many varieties in our country, and it has also been cultivated in our country for a very long time. Celery has very high nutritional value and is rich in nutrients. So there are still a great many people growing celery today, so when we grow celery, how should we manage it at the seedling stage? Below, the editor brings you the management techniques for the celery seedling stage. Let's take a look!
1. Management at the emergence stage
If the celery seeds absorb sufficient water after sprouting and a suitable temperature is ensured, then their emergence speed is still relatively fast. Under normal circumstances, celery takes about a week from sowing until full emergence. Although the time is not very long, management work still needs to be done well. Special attention should be paid to regulating two aspects: temperature and water. During the emergence stage, we should pay attention to checking the germination condition of the seeds, and also watch the soil moisture and light intensity. However, during the entire emergence stage, a shade net should be used for covering, and when the celery seedlings emerge and grow a pair of cotyledons, the shade net can be properly removed.
2. Management during the seedling growth period
When the celery seedlings grow from two leaves and one heart up to about six leaves, this is the seedling growth period. The management work during this period directly determines whether strong seedlings are successfully cultivated. First, we should pay attention to controlling the covering of the shade net. On sunny days, the time for covering with the shade net is generally from 8 o'clock to 16 o'clock, and it does not need to be covered the rest of the time. If it is an overcast day or a light rainy day, there is also no need to cover with the net. Then water and fertilizer work should be done well. If it is an overcast and rainy day, then one net and one film should be the main method, to avoid the soil being exposed to rain and excessive humidity. However, when the temperature is relatively high in summer, if the soil is dry, water should be sprayed in time.
When the seedlings grow to about 4 leaves, foliar fertilizer should be properly sprayed. For the foliar fertilizer, plant power can be used as the main type, sprayed about two times, to enhance the growth ability of the seedlings. Then special attention should be paid to temperature control, adjusting the temperature by controlling the uncovering and covering of the shade net. The temperature should generally be controlled at around 20 degrees, and must not be higher than 25 degrees at most. Finally, we should also pay attention to doing a good job in disease prevention and control, using agents such as chlorothalonil and validamycin for prevention. Spray fungicide about once every 7 days or so, and continuing for about one month is enough. Among these, the common diseases and pests of celery at the seedling stage include damping-off, seedling blight and aphids, etc.
3. Integrated management
During the growth process of celery seedlings, we should pay attention to observing the growth of the celery seedlings. Especially for celery that has just been transplanted, check in time. If there are missing seedlings or seedlings with weaker growth, then promptly replant healthy seedlings of the same growth. Then when the seedlings are transplanted, mix Jintailong topdressing treasure with water, remove the nozzle and spray the roots of the celery seedlings, to promote root growth of the seedlings and speed up the seedling recovery rate.
The above is a brief introduction to the management techniques for the celery seedling stage. That is all for today's introduction. This article is for reference only, and I hope it can help everyone!
