Latest Causes of Increased Coarse Fiber in Celery Petioles and Preventive Measures

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

I. Causes of 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 cause an increase in sclerenchyma, thickening of collenchyma, and an increase in cellulose, greatly reducing eating quality.

II. Preventive Measures

1. Choose a suitable variety

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 a low fiber content. Solid-stemmed celery contains less fiber than hollow-stemmed celery, so when planting, try to choose varieties with a low cellulose content.

2. Strengthen cultivation management

After the seedling-stopping period ends, apply 1-2 rounds of chemical fertilizer as a 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, followed by another application after an interval of 10 days. Before covering the greenhouse, apply chemical fertilizer or manure water once. When applying ammonium bicarbonate, pay attention to ventilation to avoid ammonia poisoning. In addition, when topdressing, use as little urea as possible; using too much urea will also increase the coarse fiber in celery.

3. Plant growth regulators

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

4. Harvest at the right time

Timely harvesting is also one of the measures to prevent celery from aging and increasing fiber. Celery should be harvested promptly after it has grown to maturity. If harvested too late, the celery petioles will age, not only becoming prone to hollowing but also causing increased fiber and reduced quality.
