Detailed Explanation of Key Management Techniques for Celery at the Seedling Stage
Celery is a plant in the Apiaceae family, with a great many varieties in our country, and it has 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 now, so how should we manage celery during the seedling stage when growing it? Below, the editor brings you the management techniques for the celery seedling stage. Let's take a look!
1. Management during the Emergence Stage
If celery seeds, after germination treatment, absorb sufficient water and are kept at a suitable temperature, then their emergence speed is relatively fast. Under normal circumstances, celery takes about one week from sowing until full emergence. Although the time is not very long, management work still needs to be done well. Particular attention must be paid to regulating two aspects, temperature and moisture. During the emergence stage, we should pay attention to checking the seed germination condition, and pay attention to soil moisture and light intensity, etc. However, throughout the entire emergence stage, shade netting should be used for covering. When the celery seedlings emerge and grow a pair of cotyledons, the shade netting can be appropriately removed.
2. Management during the Seedling Growth Stage
When celery seedlings grow from two true leaves and one heart until about six leaves, this is the seedling growth stage. Management work during this period directly determines whether strong seedlings are successfully cultivated. First, we should pay attention to controlling the covering with shade netting. On sunny days, the period for covering with shade netting is generally from 8 o'clock to 16 o'clock, and it need not be covered during the rest of the time. If it is an overcast day or a day with light rain, there is also no need to cover with netting. Then water and fertilizer work should be done well. If it is rainy weather, then one net and one film should be the main method, to prevent the soil from 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 appropriately 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 whether the shade netting is removed or covered. The temperature should generally be controlled at around 20 degrees, and at the highest must not be higher than 25 degrees. Finally, we should also pay attention to doing a good job of disease prevention and control, using agents such as chlorothalonil and validamycin for prevention. Spray fungicide about once every 7 days or so, and continue for about one month. Among these, the common diseases and pests of celery at the seedling stage include damping-off, seedling blight and aphids, etc.
3. Comprehensive Management
During the growth process of celery seedlings, we should pay attention to observing the growth of the celery seedlings. In particular, celery that has recently been transplanted should be checked in time. If there are missing seedlings or seedlings with weak growth, then healthy and strong seedlings of the same growth should be replanted in time. 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 recovery rate of the seedlings.
The above is a brief introduction to celery seedling stage management techniques. That is all for today's introduction. This article is for reference only, and I hope it can help everyone!
