Reasons for increased coarse fiber in celery petioles and preventive measures

During celery cultivation, one of the problems farmers fear most is the increase of coarse fiber in the petioles, which can seriously affect the variety and sales of celery and reduce profits. So what causes the increase of coarse fiber in celery? What measures should be taken to avoid it? Follow the editor to learn more about it in detail.

I. Reasons for increased coarse fiber

Normal celery has less fiber, crisp and tender petioles, and good quality. During cultivation, environmental factors such as high temperature and drought, insufficient fertilizer and water, or improper cultivation techniques often increase sclerenchyma tissue, thicken collenchyma tissue, and increase cellulose, greatly reducing edible quality.

II. Preventive measures

1. Choose suitable varieties

The fiber content varies greatly among different celery varieties. Generally, celery with green petioles has a high fiber content, while celery with white or yellow-green petioles has less fiber. Solid-stemmed celery contains less fiber than hollow-stemmed celery, so when planting, try to choose varieties with lower cellulose content.

2. Strengthen cultivation management

After the seedling hardening period ends, apply 1-2 topdressings of chemical fertilizer as seedling-promoting fertilizer, applying 15 kg of ammonium sulfate or 20 kg of ammonium bicarbonate per mu. When the plants grow to about 30 cm, apply heavy fertilizer twice, and concentrated manure water can also be applied, with another topdressing 10 days later. Apply chemical fertilizer or manure water once before covering the greenhouse. When applying ammonium bicarbonate, pay attention to ventilation to avoid ammonia poisoning. In addition, try to use as little urea as possible when topdressing; using too much urea will also increase the coarse fiber in celery.

3. Plant growth regulators

During the vigorous growth period, spraying gibberellic acid solution can not only increase yield but also reduce fiber content and improve quality.

4. Timely harvest

Timely harvesting is also one of the measures to prevent celery from aging and fiber increase. Celery should be harvested promptly after it has grown to maturity. If harvested too late, the celery petioles will age, making them prone to hollowing and causing increased fiber and decreased quality.
