A Detailed Guide to the Latest Field Management Methods for Celery
Celery is a side vegetable that many people enjoy eating very much, and it is not essentially different from Chinese celery. Because of increasing market demand, the requirements for celery yield are naturally growing higher and higher. When growing celery, if you want to increase the yield, you must do a good job of field management. How exactly should it be done? Below, the editor brings you the field management methods for celery. Let's take a look together!
1. Seedling stage management
Seedling stage management for celery is very important; when about 80% of the seedlings have emerged, the straw curtain should be properly opened each evening to promote ventilation and air movement, or appropriate shade measures should be set up above, and then when the sun is about to set, the shade net should be opened again. As the seedlings grow, the shading time can be appropriately shortened to increase the amount of light the seedlings receive. Then, with careful management, the seeds generally emerge about ten days after sowing. When the seedlings have grown to 5 leaves, they are transplanted, with plant and row spacing kept at about 45 cm, and then after transplanting, water heavily once.
2. Fertilizer and water management
Celery has very strong growth capacity, a relatively long growth cycle, and relatively high yield. Therefore, its water and fertilizer needs during growth are relatively large, so in addition to applying sufficient base fertilizer before planting, topdressing must also be done well throughout the entire growth period of celery, with the frequency and amount of fertilization reasonably adjusted according to the growth stage of the celery and the soil fertility. Water about once every 4 days or so to ensure the soil does not show white. One week after transplanting, apply topdressing once every half month, mainly with urea, diammonium phosphate, and similar fertilizers. One week before harvest, watering should be stopped to avoid affecting celery storage.
3. Cultivation and weeding
About 2-3 weeks after transplanting, celery enters the seedling recovery stage, and at this time attention should be paid to reducing the amount of watering, keeping the soil moist only. About one month after the recovery stage ends, the growth rate of celery will noticeably decline. At this time, we must do a good job of cultivation and weeding to avoid soil compaction, ensure that a small amount of water can penetrate the soil, improve soil permeability, and promote the growth and development of celery roots. Then carry out weeding to prevent too many weeds from affecting the growth of celery. However, they should not all be removed, so as to provide some shade for the celery.
4. Pest and disease control
Pest and disease control for celery is also a management task that needs to be done with emphasis. Common pests and diseases of celery include leaf spot disease, aphids, and so on. When planting, we must disinfect regularly and check the growth condition of the celery. Control fertilizer and water well, and do not apply excessively, to prevent fertilizer damage and waterlogging damage from triggering pests and diseases. We should appropriately understand the symptoms and control methods of several common celery pests and diseases. For example, when leaf spot disease occurs, use agents such as chlorothalonil or carbendazim for spraying control, once a week, for one month, and so on. This allows the specific cause to be identified in time, and then corresponding measures to be taken.
The above is a brief introduction to celery field management methods. When celery grows to about 40 cm, it can be harvested. Pay attention to the harvest time; it must not be harvested too early or too late, otherwise it will have a relatively serious impact on the yield of celery. That is all for today's introduction.
