However, some growers grow celery, it is easy to appear dead during the winter, so what is the reason? Xiaobian this will explain in detail the reasons for the death of celery during the winter and preventive measures.
First, the main reason for the death of celery during the wintering period
1. The celery seedlings are too small and have insufficient resistance.
2. The soil in which celery is grown is dry early, and the soil moisture is poor, which is easy to cause dead seedlings.
3. The weather temperature is low, and the cold-proof measures of celery during wintering are not in place, causing the celery seedlings to freeze to death.
4. If celery encounters catastrophic weather such as blizzard during the winter, it is very vulnerable to damage and death.
Second, the prevention measures of celery during the wintering period
1. Cultivate age-appropriate seedlings: When celery is planted, timely sowing and planting should be carried out to strengthen the management of celery seedlings. Choose celery with soil with strong water and fertilizer retention capacity, apply enough base fertilizer, and prepare well. Ditch can cultivate a strong seedling of appropriate age and have sufficient resistance to the bad environment outside.
2. Watering the antifreeze water in time: Generally, the celery is watered during the wintering period, and it can be frozen at the local nighttime, and the frozen water should be poured during the daytime thawing.
3. Take measures to prevent cold: Before the cold wave comes, it is necessary to set up a wind barrier in the north of the ditch to prevent the north wind from blowing down the celery seedlings. It is also possible to cover the surface of the grass with a straw or grass curtain of 10 to 140 cm thickness to prevent cold air intrusion.
4. Timely prevention of severe weather: In the event of heavy wind and snow, it is necessary to pay attention to the reinforcement of wind barriers and other facilities, and to compress the coverings such as straw curtains. When the weather is fine, clear the snow in the celery field.
