What is the reason for the hollowness of celery in the latest autumn and winter greenhouse

Celery cultivated in warm water in autumn and winter is very prone to the increase of hollow and fiber, which greatly reduces the commodity value of celery and brings huge economic losses to farmers. So what is the cause of celery hollow? How to prevent and cure it? Let's get to know it.

1. High temperature and low temperature environment

The cultivation of celery is mostly carried out through the greenhouse in autumn and winter. if the temperature and humidity in the greenhouse are not properly grasped in the cultivation process, the high temperature and low humidity environment for a long time will easily lead to celery hollow. High temperature will accelerate the tissue differentiation of celery, while low temperature can not meet the water demand of the plant, which leads to the decomposition of plant pith tissue and the increase of celery hollow and fiber. Therefore, in order to avoid these situations, greenhouse cultivation must do a good job in controlling the temperature and humidity. The temperature should be sowed between 15 and 23 degrees, and not less than 10 degrees at night.

2. Lack of fertilizer and water

Celery root distribution is strong and underdeveloped, so the absorption capacity is limited, once the lack of fertility, it is easy to appear hollow and fiber increase phenomenon. Therefore, once the fertilization should be reasonable, more phosphate fertilizer should be applied at the seedling stage. the lack of phosphate fertilizer will lead to thin seedling growth and leaf differentiation, and hollow will appear in the later stage. There is the cultivation of celery in autumn and winter, we are afraid that watering will cause a drop in ground temperature, affecting the normal growth of celery, in fact, as long as proper watering, not only will not affect the growth of celery, but also promote its growth. Generally every half a month watering, the amount of water should not be too much, to small water, to the first half of the harvest, to water twice.

3. The harvest is too late

Celery hollow is also related to the harvest time, if the harvest time is too late, its fiber tissue continues to grow, resulting in root absorptivity in summer, stem and leaf aging phenomenon, so hollow phenomenon appears. Therefore, in the harvest, we must pay attention to the harvest must be timely harvest, must not delay time, but the counter-effect of the session.

The above is the introduction of celery hollowness in autumn and winter greenhouse. I hope it can help you. If you want to know more about it, please follow us.
