Latest Compilation of Precautions for Growing Celery in Summer
Celery is a side vegetable that many people enjoy eating very much. When stir-frying, many people like to add a bit of celery for seasoning. Therefore, the current market demand for celery is relatively high, and the planting area is also continuously expanding. So as summer gradually arrives, there are many aspects of growing celery in summer that we need to pay attention to. Today, the editor has brought you the precautions for growing celery in summer. Let's take a look together!
1. Sowing and Raising Seedlings
The temperature in summer is very high, and celery seeds germinate very difficultly under high-temperature conditions, so we must pay attention to doing a good job of pre-germinating the seeds. When pre-germinating the seeds, the temperature should be controlled at about 18 degrees. It must not be too high, otherwise the pre-germination will not have much effect. After sowing, pay attention to shading, water appropriately, keep the soil moist, and promote seedling emergence. However, the amount of water should not be too much, and drainage work should be done well during the rainy season. Then, when the seedlings grow two leaves, thin the seedlings. When the seedling age reaches about two months and the seedlings are about 18 cm, they can be called strong seedlings.
2. Planting Density
The planting density of summer celery must be strictly controlled. Only by ensuring the robust growth of each seedling and coordinating the growth relationship between the overall celery and individual seedlings can the yield be effectively increased. The planting spacing between plants and rows should be controlled at about 7*10 cm. During the first seedling-stunting of celery, control the amount of watering well, generally watering once about every week, keeping the soil dry-wet alternating. Then during the second seedling-stunting, pay attention to also controlling the temperature well. Improve the ventilation inside the shed, controlling the daytime temperature at about 19 degrees and the nighttime temperature at about 14 degrees.
3. Temperature Control
As just mentioned, the high-temperature environment of summer is actually very unfavorable for the growth of celery. Celery has strong cold tolerance, but its heat tolerance is very poor. When planting in summer, we should keep the daytime temperature at about 20, and control the day-night temperature difference at about 7-8 degrees. If the temperature is too high, it will have a fatal impact on celery. Therefore, when planting, we must improve the ventilation inside the shed, ventilate appropriately, and maintain air convection. Ventilation can effectively reduce the temperature inside the shed.
4. Adjusting Light
Light is also very important for the growth of celery. Under low-temperature and long-day conditions, celery is very prone to bolting due to the photoperiod. Therefore, we must do a good job of adjusting light. When planting in summer, if it is greenhouse cultivation, then cover the greenhouse film to avoid direct sunlight. If it is open-field cultivation, then after planting, be sure to set up a shade net to avoid direct sunlight while providing celery with an appropriate amount of scattered light. Then pay attention to cleaning the greenhouse film well, and also ensure a certain degree of light transmittance.
The above is a brief introduction to the precautions for growing celery in summer. There are many aspects of growing celery in summer that we need to pay attention to. In addition to the above, there are also pests and diseases, humidity, fertilizer, and so on, none of which can be ignored. That is all for today's introduction.
