Winter celery technology
The cold resistance of celery is strong, especially the seedling stage can tolerate the short-term low temperature of -10°C. Using this feature, the seedling stage will pass through the winter in the shed, and after the spring, it will turn into normal growth with the increase of temperature.
Fertilizer and water management Celery enters the growth period and grows faster. It requires more fertilizer and water. In this period, we must keep the soil moist and supply celery with sufficient water and nutrients. In this stage, watering is performed by means of irrigation, and nitrogen fertilizer is applied in combination with watering. When topdressing urea, urea can be added to a bucket of water to dissolve it, and it can be applied to the field with water irrigation. The combination of watering and fertilization can make the fertilization uniform and facilitate the rapid development of fertilizer efficiency.
Cold insulation due to the suitable growth temperature of celery is 15 °C - 20 °C, the temperature is below 15 °C long-term poor growth of celery, the use of greenhouse cultivation celery the main insulation measures is to cover straw. If there is no cold weather on sunny days, we can retract the straw curtains at eight or nine o'clock in the morning. This will not only help increase the room temperature, but also increase the light and promote the growth of celery. And spray a new high-fat film, water evaporation points, anti-bacterial infections, freeze-thaw insulation.
